Thermal Expansion Tank Tie-In in Eagar, AZ

Install a backflow preventer on a home's main line and you have created a closed system. When the water heater runs, heated water expands and has nowhere to go. Pressure climbs until the temperature and pressure relief valve on the heater, set at 150 psi, starts to weep.

A thermal expansion tank fixes that. It is a small steel tank with an air bladder, tied into the cold supply near the heater. The bladder absorbs the expansion.

The detail people skip is the air charge. The tank has to be pre-charged to match your static water pressure, checked with a tire gauge before it goes on. A tank left at the factory 40 psi on a 70 psi system does very little.

Sizing depends on heater capacity and water pressure. A 40 or 50 gallon heater usually takes a 2 gallon tank.

Backflow testing FAQs

Questions about backflow testing

Questions we hear most often about Thermal Expansion Tank Tie-In in Eagar, AZ.

Talk to a person
Who is allowed to test my backflow device?
A tester who holds a backflow tester certification recognized by your state or your water utility. Many utilities keep an approved tester list and reject reports signed by anyone not on it.
Why is water dripping from my RPZ relief valve?
A steady drip usually means debris is holding the first check open or the relief valve diaphragm is worn. A cleaning or a rebuild kit fixes most cases.
Does my lawn sprinkler system in Eagar, AZ need a backflow preventer?
Almost every US plumbing code requires one on irrigation, since fertilizer, pesticide and standing water at the heads can siphon back. The device type depends on local code and how the system is laid out.
What does a failed backflow test mean?
A check valve or the relief valve did not hold its required pressure differential. The device needs repair or replacement, then a retest before a passing report can be filed.
What is a cross-connection?
Any point where drinking water piping can come into contact with a non-potable source. Common examples are a hose in a bucket, a boiler fill line and an irrigation system.
