Delta Showerhead with H2Okinetic Technology
Everyone knows about low-flow showerheads. They’re better for the environment because they use less water. They’re better for your energy bill because your water heater works less. At a glance, it seems like a win-win situation. The problem is that not all low-flow showerheads are built equal.

Delta is back in the spotlight with a new proprietary technology called H2Okinetic. This is a new feature for low-flow showerheads that really gives you a better shower experience.
What is H2Okinetic Technology?
Delta’s claim is that showerheads equiped with H2Okinetic technology result in a warmer shower with drenching coverage, all while complying with low-flow standards. This is achieved by utilizing larger water droplets that retain heat longer and completely envelope the user.
H2Okinetic technology is built into the showerhead- there’s no additional installation. It doesn’t feature any moving parts, resulting in a very quiet showerhead. All these attributes combine to create a water-saving showerhead that doesn’t feel like one.
Delta recently shipped us the Addison Monitor 17 series to review and I installed it last week. Read on for a comprehensive review and my overall conclussions.
Delta Addison Monitor 17 Showerhead Review (Model T17292-RB)
- The Good: H2Okinetic technology, excellent water-pressure, good “drenching coverage”.
- The Bad: The Addison retails for $282.75 but is available at greatly discounted prices from other online retailers.
- Overall: This is an exceptional showerhead. Beautiful styling and the 2 gpm flow rate feels more like 3.
Features and Performance

The design was the first thing I noticed about this showerhead. It’s amazing style is inspired by “scallops of a sea shell” and features graceful curves. It’s available in chrome, Aged Pewter, Brilliance® Stainless or Venetian Bronze®.
Water pressure is an important aspect of a good showerhead and the Addison had excellent pressure. Water was delivered in a strong, steady stream.
The controls incorporate a dual function, pressure balance cartridge. One dial controls the temperature while the other adjusts water volume. This is important because it allows you to set the temperature and leave it- no more water temperature guess work.
This showerhead mounts to a standard size shower arm. It’s a water-efficient, H2Okinetic Technology raincan showerhead that outputs 2.0 gpm @ 60 psi- using 36% less water than standard showerheads. It also has ScaldGuard®, which protects against sudden temperature or pressure changes
Price and Where to Buy
This product (Venetian Bronze finish) has a MSRP of $240.00- a fair amount. Fortunately, this same showerhead and controls is available from Amazon at about a 90% discount! Here’s the link:
Also, keep in mind that different finishes carry different price tags.
Note: Delta Faucet provided us the Addison Monitor 17 Series as part of a test kit. Our reviews are objective and we are not compensated for a positive review.

Geico vs. AllState for Auto, Home, Landlord, and Umbrella Insurance
We just saved a bunch of money by switching our car insurance to Geico!
I’ve always wanted to say that
But seriously, we did just switch all of our policies over to Geico from Allstate.
We’ve been in the “good hands” for about 6 years. Turns out that those hands are also expensive.
And they’re not as good as they used to be…
I wrote last year about Allstate’s new tropical cyclone deductible, which would make a homeowner pay a 3% deductible before covering any damages caused by a named storm. And by 3%, I mean 3% of the value of the house, not 3% of the damages. That would make our deductible more than $10,000 before Allstate chipped in a dime for a disaster like that.
So I’ve been meaning to switch our coverage since that notice came out, but like so many things it slipped by. Since all of our policies renew on April 15, I decided it was a good time to look around and see if we could do better.
I’ll bet every one of our American readers has heard at least a dozen Geico insurance commercials. They’re everywhere; they’re catchy, and they make bold claims… 15 minutes could save us 15% or more on our car insurance by switching. I’ll be honest, I didn’t really buy it.
But, when I Googled for “home insurance quotes”, I discovered Geico offers homeowners and landlord insurance. I figured I’d give the 15 minute claim a test. (I learned later that Geico Homeowner’s insurance and Landlord’s insurance is underwritten by Travelers).
The phone call took a lot more than 15 minutes… It actually took about an hour to get everything squared away.
I won’t bore you with all the details, but here’s how the numbers panned out…
Auto Insurance Comparison
We have a 2003 Toyota Corolla and a 2006 Dodge Grand Caravan. We live in a busy suburb of Maryland.
- Allstate: $978 / 6 months
- Geico: $567 / 6 months
–> Geico is $822 cheaper for 12 months.
Homeowner’s Insurance Comparison
For $400,000 of coverage on the structure with good coverages for other aspects.
- Allstate: $1216 / 12 months
- Geico: $1176 / 12 months
–> Geico is $40 cheaper for 12 months.
Landlord Insurance Comparison
For $175,000 coverage on the structure with good coverages for other aspects.
- Allstate: $482 / 12 months
- Geico: $605 / 12 months
–> Geico is $123 more expensive for 12 months.
Umbrella Insurance Comparison
For $1,000,000 in additional liability protection.
- Allstate: $355 / 12 months
- Geico: $182 / 12 months
–> Geico is $173 cheaper for 12 months.
Total Savings Switching to Geico
All told, Geico came out $912 less than Allstate for identical coverage, or about 25% less. We actually reduced some of our structure coverages because Geico advised us that we simply didn’t need as much as we were carrying, for an additional savings of about $200.
Of course, Geico doesn’t have the tropical cyclone deductible–at least not in Maryland–which is a huge plus.
Now, we’re not wed to Geico. If another reputable company can best their offer, we’re game. But we will stick with them for the next 6 months at least, since we spent their time getting signed up. And I will ride the ’savings high’ for a little while…
Goodbye good hands. Hello, gecko!
Tools for Laying Ceramic Tile
If you’ve been reading along, you know that I’m renovating my guest bathroom. My daughter is 13 months old and getting too big for the kitchen sink so it’s time to get this bathroom in order.
Here’s my progress so far:
Before you begin laying tile, you need to make sure you have the right tools for the job. Some tools make a job easier while other tools are an absolute necessity. This post will walk you through the different tools and what I’m using to lay my floor.
Tools for Installing Tile
Here’s the list of tools, grouped by task with brief explanations. This list does not include materials for laying tile (like spacers or grout).
Measuring – chalk line, tape measure, square
Before you lay that first tile, create at least two guides. You’ll need a chalk line, tape measure and square. The chalk line creates a highly visible, straight line. Use the square to ensure the lines are accurate. The distance from your guide, to the wall will reveal if your walls are square.
Mixing Thinset – bucket, mixing blade, drill/driver
Thinset is the adhesive that will fasten your ceramic tile in place. You can purchase pre-mixed tubs of thinset or mix your own. To mix thinset, grab a bucket- a 5 gallon bucket is best for most jobs. Make sure you have a heavy-duty mixing blade. Paint mixers are not up to the task and may leave pockets of unmixed compound. Use the mixing blade with an appropriately powerful drill/driver.
Laying Tile – trowels, grout float, sponge
Many people use a margin trowel to begin spreading thinset. I don’t have a margin trowel and use a broad putty knife instead. Notched trowels are available with varying notch sizes and styles. I have a ¼”, square-notched trowel to comb the thinset. Make sure you have the right size and style for your job. It’s also a good idea to have a straight, spare piece of wood to make sure all the tiles are nice and even. A grout float is used to apply grout after the tile is set. It features a rubber face with rounded corners and edges for smoothing the grout in place. Thinset can be messy. Keeping a wet sponge nearby makes it easy to clean as you work. Hardened thinset can be very difficult to remove.
Cutting Tile – nippers, wet saw
There are several tools available to cut ceramic tile but most jobs can be accomplished with a set of nippers and a wet saw. Nippers are great for making curved or irregular cuts in tile. Most feature a carbide tip and basically bite off a portion of the tile. The majority of cuts will take place on your wet saw. Use it to make accurate, straight cuts.
What do you think? Any tool suggestions that I left out?
Hardwood Flooring
Hardwood flooring is the single most dramatic upgrade you can make to a home given the time and cost of installation. Hardwoods work in almost any design and in just about any budget. Hardwoods are versatile. While some species, cuts, and finishes turn an informal room into an elegant showpiece, others can transform a bar area into a rustic, western-style saloon.
The web is chock full of resources on hardwood floors. With some diligence, you can learn which hardwood floors are the hardest, what types of hardwoods are best for kitchens and baths, and what’s the best hardwood to go with cherry cabinets.
You can also find out that while hardwoods don’t add appraised value to most homes, they do add sales appeal, which can translate into real dollars at closing.
Even with all the available information, we think another resource can’t hurt — one that brings much of the information into a single place, with added information from our personal experience.
We’ve installed numerous hardwood floors in the past, and we’re about to tackle the job again in an upcoming project. So this series will be a lot of fun for us to write. In fact, with each article, we’re going to come back and update this index. Since we’ve already written a number of articles on the topic in the past, those are linked up below.
Pretty ambitious? We think so. But where would we be without ambition?
So stay tuned this Thursday for our first installment. Here’s a preview of all the articles to come (and some with links already written).

Decorative Shelving to Add Style
Decorative shelves are a great way to add interest and function to any room. As I have slowly decorated my house, I have used mirrors, pictures, fabric wall hangings. But I found that I had other small items I wanted to incorporate into the space without adding clutter. I found shelving to be a creative solution.

Choosing Decorative Shelves
Material:
The material of the shelving, whether glass, wood, or metal should be a reflection of the already existing color and decor present in the space. I chose white, painted wood shelves to incorporate more light into the space. Also, the two rooms, Izzie’s and the powder, have a soft, fresh look, so glass and metal shelves would look too cold and darker, stained wood shelves would appear too formal. Also, consider what items you will be putting on the shelf – wood shelves are sturdier and can hold more weight.
Brackets:
There are many styles of brackets to choose from once you choose the material of the shelf. Brackets can be decorative, basic and functional, or hidden entirely. I have found that decorative brackets can make shelving look more unique and can help to integrate the shelf into existing decor. Do not feel trapped into sets of shelving and brackets sold together; if you don’t like the look paint them or make your own!
Style:
The combination of material and brackets can create very different looks and again, should reflect the style of the room, whether it is modern, rustic, or whimsical. Step back and assess what feel your room has before purchasing. Even take a picture and bring it with to the store to ensure the shelving will compliment your existing look. If your room is more modern, with bold colors, consider glass shelving with geometric brackets. If your room is rustic, consider bulkier, unfinished wood shelving with iron brackets.
Design:
Once you have chosen the shelving and brackets that will fit with the style of the room, consider the number and size of the shelves, spacing, and arrangement. For smaller spaces, use fewer, smaller shelves. For larger spaces, increase the number of shelves and the width between them. Play with the arrangement – assess how the spacing and location of the shelves will draw your eye and open (or close) up the room. Also, think about what items will be placed on the shelf – the item should not be proportionally too large for the chosen shelf. If taller items are to be placed on the shelf, remember to increase the space between the shelves if another shelf is placed above.
Price:
Shelving can be a great way to use and organize already existing nick-nacks and collections. It is also a cheap alternative to expensive art. Home Depot, Amazon.com, and Ikea all have great shelving options and varying prices to meet your price bracket!
What do you think? How have you used shelving to add a creative flare to your space?
Ceramic Tile over Plywood or OSB
Ceramic tile is a very popular upgrade for kitchens, bathrooms, patios, and foyers. It is resistant to water and scratches, making it more durable than hardwoods or vinyl tile for these areas.
We’ve installed a number of ceramic and stone floors. The job isn’t difficult when it’s done right… But done wrong, it can leave a homeowner with a feeling of defeat. A poor ceramic installation will delaminate from the subfloor, split at the grout lines, or worse–crack directly across the tile.
One question that folks new to ceramic tile frequently ask is whether they can lay the ceramic directly on top of a plywood or OSB subfloor, using a thinset cement or liquid nails to glue down the tile to the wood.
Problems with Ceramic Directly on Plywood or OSB
The basic answer to whether you should lay ceramic directly over plywood or OSB is simple: you shouldn’t do it. Here’s why:
Plywood and OSB expand and contract with humidity and temperature much more than ceramic tile. Regular seasonal humidity shifts are significant enough to make the average 10′ x 10′ wood subfloor floor expand or contract as much as 1/2″. Ceramic tile doesn’t expand/contract nearly as much. As the plywood or OSB expands, the ceramic won’t. You’ll begin to see hairline cracks in the grout, then the grout will crumble a bit. Eventually, after several seasonal cycles, tiles will begin to come loose or crack.
Plywood and OSB have surface imperfections. This concern is significantly less important than the first; but it is nonetheless still a concern. Plywood and OSB frequently have imperfect joints and surface textures. While these could be smoothed over with thinset, they are much harder to manage than the correct solution.
Proper Way to Lay Ceramic on Plywood or OSB
There are two materials commonly used for laying ceramic on plywood or OSB that are applied before the tile:
Concrete Board – Concrete board, also called Backer Board comes in 1/4″ and 1/2″ thicknesses and is usually sold in 4′ x 6′ sheets. It should be fastened to the subfloor using thinset, and then screwed down every 10″ square. Screws should be kept at least 2.5″ from the edge of the board, since it is prone to split. You should use a 1/4″ slotted trowel to apply the thinset. Leave 1/4″ gaps between each board.
Concrete board has similar expansion properties to ceramic tile (it doesn’t expand/contract much at all). The combination of thinset and screws prevents the plywood or OSB from expanding beneath the concrete board, thus creating a strong bonding surface for the tile that doesn’t shift with thermal or humidity changes.
Once the concrete board is down, you fill in the 1/4″ gap with thinset and a special mesh tape available anywhere ceramic products are sold.
There are a number of concrete board manufacturers including the popular hardiebacker. Check your local home improvement store or ceramic tile shop.
Ditra – This is a special plastic material made by Schulter (official site). The unique geometric design decouples the subfloor from the surface of the Ditra, effectively serving the same function as concrete board. Ditra should be set with thinset using a 1/8″ trowel.
Once laid, the surface of the Ditra is suitable for ceramic installation. You can either use a 1/4″ trowel and apply enough thinset to fill in the gaps, or you can skim coat the Ditra first using the flat side of the trowel and then use a 1/4″ trowel to lay ceramic in a two step process.
Good Results From Proper Tiling
Using backerboard or Ditra to mediate the expansion and contraction of the subfloor will lead to a much longer lasting and professional-looking tile job that is much less likely to cause trouble in the future.

How Motion Sensors Work
Motion sensors are a great security feature to incorporate into your home. Most criminals and mischievous kids will take off when a light turns on. This post will focus on some of the technology behind motion sensors and explain how they work.
Passive System Motion Detectors
Most homes utilize a passive infrared (PIR) motion sensor that will trigger a light.
- Passive systems don’t actively add anything (sound, laser, etc.) to the environment around them. Passive systems simply monitor the surrounding area.
- Infrared (IR) is light with a wavelength between 700 nm and 300 µm. The human eye can’t see it, but sensors can detect it.
What PIR Sensors Detect
PIR sensors act like a photosenser for electrons. Infrared light conducts electrons off an object and those electrons become a signal to the sensor. Most sensors look for a rapid change in IR energy otherwise more subtle changes, like asphalt cooling, would trigger the sensor. That’s why it seems like movement will trip the sensor.
What the Lens Can See
Most motion lights feature a plastic lens with one or two IR sensors. These lenses are typically curved to bend light and provide a much wider field of view. However they cannot “see” through everything. Glass is one substance that blocks IR energy.
What do you think? Have you ever investigated your motion detector?

Preventing an Ice-Frozen Heat Pump / Air Conditioner / Compressor – Setting the Defrost Timer

Last year, I wrote about fixing the ice-frozen outside compressor unit for our heat pump. This winter has been record-breaking for precipitation here in Maryland, however, so I found I needed to readdress the issue with our HVAC guy. What I learned? I can adjust the frequency of the compressor’s defrost cycle on my own to keep up with whatever Nature sends us.
With all the freezing rain and snow we’ve experienced this fall and winter, our compressor’s defroster just wasn’t keeping up. Turns out, it was set to run only every 90 minutes of running time. An energy-efficient setting, but not frequent enough for this year’s weather.
Mike showed me where to adjust the settings inside the removeable side-panel on the outside unit. Yours should look much the same.
We moved the white clip from the 90 minute setting to 50. If that turns out not to be frequent enough, we will move it to 30 minutes, but so far we seem to be doing fine with 50.
So depending on where you’re living, how cold it is, how much precipitation you’re getting in the cold weather, and where your outside unit sits (ours is under our deck – never directly in the sunlight!) you can adjust your defroster settings accordingly. For those living in the southern U.S., you should be fine with the 90 minute setting. Our friends in Canada and the northern U.S. states may need it to run every 30 minutes in the winter.
Note that the settings are how often the defroster kicks on during system run-time. So if your compressor runs for 10 minutes, turns off for a half an hour, then runs again for 15 minutes, that’s 25 minutes of run-time, even though 55 minutes have elapsed. Ours was going a few hours before it had run for the requisite 90 minutes to engage the defroster and that was too infrequent for our unit this winter.
Running the defroster does, of course, use extra energy, so you don’t want it to run more frequently than you need it. That’s why we dropped to every 50 minutes rather than jumping straight to a defrost cycle of every 30 minutes of run-time. Should we have a really mild winter again in the future (as we have most years in the past), I may move the setting back to 90 minutes. But for this year, it’s not worth the risk of damaging the unit (ice-chunks building up and causing damage to the spinning fan blades and subsequently to the motor) just to save a few cents in energy cost each week.
Hope this is helpful to someone else out there! It’s a quick and free first-resort solution for dealing with an iced-over unit that otherwise is in good working condition (and can help trouble-shoot before you call an HVAC repair person and pay for a visit).
Print Wirelessly with Airport Express
Izzie is getting more and more mobile and that means she is getting into more and more stuff. Originally, we had our printer on the floor below a small computer desk. She was constantly trying to crawl (and drool) all over it. Now, I’ve got the printer safely stashed on an out-of-the-way shelf. Thanks to my Airport Express, any computer in the house can print from any location.
Researching a Print Server
I have a Canon MP600 inkjet printer (Canon site). It’s a nice little printer / scanner / copier. After looking several print servers and reading a lot of reviews, it became apparent that no print server is really designed to support a multifunction printer. They support printing but not scanning (or faxing if you have that feature).
I have several Apple brand products. They all work well, especially with each other, so I decided to continue with the Apple Airport Express (Apple site). All the reviews had positive things to say and Fred used an Airport to setup a wireless speaker system. Click here for his full Airport Express review. Here’s my experience.
Airport Express as a Print Server
Setup
Setup was an easy matter. I bumped into some software confusion but simply reset the Airport and updated my software. To reset your Airport, press and hold the small button by the audio port. The Airport came with a CD with the latest software version.
The other potential problem depends on what type of security your wireless router employs. The Airport Express is designed to work with WPA encryption- something that I already had setup.
When I installed the MP600 on the computer, it went flawlessly. The printer showed up in the list (as it should) as a bonjour connected device.
Printing
Printing is the same as through a USB connection. The only difference I can find- it takes just a few more seconds before the print job starts.
Where to Buy an Airport Express?
You can learn more about the Airport Express at Apple’s Airport Express Official Site. If the device is right for you, you can save 5% off the retail price ($99) by picking up the airport express at Amazon. Amazon ships the unit for free and you can avoid sales tax in some locations.
What do you think? Do you have an Airport Express for printing?
You Can’t Trust Real Estate Agents to Get You the Best Price for Your Home
I recently finished reading Freakonomics, an excellent book by economist Steven Levitt and journalist Stephen Dubner that explores how incentives affect people in ways that we wouldn’t always intuit. They apply the disciplines of economics and statistics to other-than-financial scenarios, like exploring the unusually high incidence of cheating in Sumo Wrestling (a sport that boasts honor as a central theme).
One of my favorite parts of the book deals with whether real estate agents garner higher sale prices for their clients than if the client were to simply sell the house on their own. In order to tease out the answer, Levitt and Dubner look at a variety of sales data in a particular locale and examine the average sales price differences between agents’ selling their own homes vs. other people’s homes. They also looked at how long a property was on the market in each situation.
What did they find?
As you might expect, they found that, on average, a real estate agent’s home sold for more money, and stayed on the market longer than a typical property. They also found that, on average, homes sold with the assistance of an agent didn’t sell for any higher than those homeowners who sold on their own.
What Levitt and Dubner found didn’t really surprise me… it all comes down to incentives.
Realtors Are Motivated to Sell Properties Fast, Not at a High Price
Most real estate agents in today’s market charge 5-6% of the sales price of the house for their services. Of that amount, half is usually provided as an incentive for the buyer’s agent, making the selling agent’s take only about 3%. But, that 3% is usually split 50/50 with the agent’s company, which means that the agent is likely to get about 1.5% of the sales price.
Let’s say you have a house that’s worth $250,000. With some effort and marketing, a real estate agent can get you full price. But, with less effort and marketing, they can get $240,000. To you, the difference between $250,000 and $240,000 is a whopping $10,000 – more than 2 months pay for most Americans.
But what’s the difference in the agent’s take? 1.5% of $250,000 is $3,750, while 1.5% of $240,000 is $3600, a difference of only $150!
If selling the property for $250,000 takes 20 more hours of work (e.g., additional showings, open houses, etc.), you can see that it just doesn’t make sense. The Realtor would only be working for about $7.00 / hour for those hours.
A Better Way to Pay A Real Estate Agent
So if straight commission isn’t a good way to pay, what’s the better alternative?
Levitt and Dubner don’t get into this… but I think the best way is to set a basic fee for listing the house, and then pay a large incentive above a certain sales price.
For instance, you might pay $1000 for standard listing services, and then 50% of the price above some base price. In our example, perhaps we would pay $1000 for basic listing and settlement services, and 50% of the sales price above $250,000. In this model, our agent is highly motivated to exceed the target sales price of $240,000 by as much as possible, since his take is highly dependent on sales price.
Of course, this relies on homeowners knowing approximately what their home is worth and being willing to negotiate with the agent. Unfortunately, since real estate agents are the ‘experts’, they normally dictate the compensation model. Most people buy and sell houses only a few times in their whole lives, and aren’t really ready to negotiate these terms. In most cases, they also wouldn’t know what is ‘fair’ for the base price, and being off by even $10,000 in this attribute could lead to paying an inordinate fee to the agent.
What do you think about Real Estate Agents?
I’m really curious what you think about real estate agents.
Are they worth the price? Is there a better way to motivate them to get the highest price available? How do you make sure your not getting ‘taken’?
