Thermal Expansion Tank Tie-In in New Salisbury, IN

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 New Salisbury, IN.

Talk to a person
How often does a backflow preventer need testing in New Salisbury, IN?
Most water utilities require a test once a year. Many also require one at installation, after any repair and after the device is moved. Your utility's notice letter gives the exact due date.
Does my lawn sprinkler system in New Salisbury, IN 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 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.
Is fire sprinkler backflow testing different?
Yes. Along with the standard check valve test, NFPA 25 calls for an annual forward flow test on fire line backflow assemblies. Results often go to both the water utility and the fire authority.
Can a backflow preventer be repaired instead of replaced?
Often it can. Rebuild kits with new discs, springs and seals are sold for most brands. Replacement makes more sense when the body is cracked or parts are no longer made.
