How hot is too hot? We recently observed this hot water heater on a Leavenworth home inspection in the upper Wenatchee Valley. Aluminum branch circuit wiring was used to supply the hot water heater’s energy. Improper installation caused a potential dangerous situation. The unions between the aluminum and copper wire created galvanic corrosion which can weaken the terminal at the switch, receptacle or union. As the branch circuit is energized the aluminum and copper wires expand and contract at different rates causing the terminal termination at the switch, receptacle or union to loosen. The loose connections can allow arcing and pitting, creating a hazard for shock or fire, and eventually causing the circuit to fail. To learn more information about aluminum wiring read my earlier blog entry.
And the hot water heater was still being used, but not anymore! Based on our inspection they hired a professional electrician to fix the improper installation. Do you want to know how your home is performing? An AMS Home Inspection can indentify potentially dangerous conditions.

This picture was taken last week at a Lake Wenatchee Home Inspection. The metal carport was no match for the heavy snow we received over the last winter. Notice how much snow we still have there…in April!

This week one of our staff went to a WSU Extension Energy Program training in Wenatchee with a focus on duct sealing and testing requirements for the 2009 Washington State Energy Code for HVAC: 503.10.3 Sealing. We have two Energy Star Performance Technicians on staff so this class was more of a refresher course on duct testing but we did benefit from understanding more about the changes to the new HVAC requirements. Basically, the code is in a trial period. Contractors must test the HVAC now but do not have to meet the target rate of allowable leakage during this 120-day testing period. In April 2011 a judicial committee will listen to arguments from all sides and make a decision about the 503.10.3 Sealing WA State Energy Code.
We performed a HVAC leakage test on a home in South Wenatchee. The new construction home performed well. It would have passed the new requirements. It was interesting to note the small leakages that could be easily fixed by mastic. The equipment used for testing the HVAC includes a duct blaster, manometer and blower door which could add up to $5,000. This is a new expense to contractors. There is also discussion about requiring third party testing due to conflict of interest. Should HVAC contractors be able to test their own work?
Here are a few interesting facts we learned in class this week. Did you know that 40% of a home’s fresh air comes from the crawl space or garage? Thinking about cleaning those spaces right now…aren’t you!? This is also a good time to remind you to open your garage door any time the car is on. A family of four can emit up to 3 gallons of water into a home daily from sweating, showering, cooking, etc. Where do the 12 gallons of water go? Be sure to use your oven and bathroom exhaust fans regularly!

Thermal expansion of water in a closed plumbing system can create a number of annoying and potentially dangerous problems. These include: unusually high pressure in a system, pressure surges, and the chronic or continuous dripping of a temperature and pressure (T&P) relief valve. In addition, dripping faucets and leaking toilet tank ball cock fill valves are also symptomatic of thermal expansion. More serious problems can also occur due to thermal expansion. When dangerous pressures are built up in a water heater, internal parts may fail such as the internal flues, fittings or water connections. If a flue way collapses it can lead to the potential release of toxic gases, such as carbon monoxide into living spaces.
Virtually, every modern plumbing code requires the installation of an expansion tank on hot water heater installations. The reason is simple. Water expands when heated. This extra volume of water needs to go somewhere. Before the widespread usage of backflow preventers, check valves and pressure reducing valves, this expanded water simply pushed the cold water back into the city water main. Now with these devices required in new construction and most permitted remodels we have successfully closed this system.
Where does the pressure to go?
Expansion tanks are really simple devices. They contain compressed air and a special rubber bladder. When your hot water heater turns on, the water within your piping system begins to expand. This expanding water slowly enters the expansion tank as the water is brought to temperature. Eventually, hot water is drawn from the system thru a faucet and the expansion tank releases the extra water into the piping system.
The installation of an expansion tank is a simple upgrade for any hot water systems. There are some things you need to know before running out and purchasing your unit such as existing water pressures, capacity of the hot water tank, and ensuring the unit you purchase is for potable water systems. I always recommend working with a licensed plumbing contractor.
