Thermal Expansion Tank Tie-In in Hyde Park, UT

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 Hyde Park, UT.

Talk to a person
How long does a backflow test take?
A residential PVB or double check test usually takes 20 to 30 minutes. Large commercial and fire line assemblies take longer.
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.
Do I need an expansion tank after installing a backflow preventer?
Often, yes. The device makes your plumbing a closed system, so heated water cannot expand back to the main and the water heater relief valve may start dripping.
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.
