Thermal Expansion Tank Tie-In in Saint John, 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 Saint John, IN.

Talk to a person
What happens if I miss the backflow test deadline?
Utilities usually send a second notice, and after that some add a fee or schedule a service shutoff. Calling (833) 990-5874 before the deadline is the simplest way to avoid it.
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.
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.
How much does backflow testing cost in Saint John, IN?
Pricing depends on device type, size and the local market. Call (833) 990-5874 for current pricing on backflow testing in Saint John, IN.
