There’s no guesswork with the thermal expansion relief valve. Installed in the same place as an expansion tank, it’s a combination of a ball valve with a relief valve that opens and drains water to a pipe drain once water pressure hits 125 psi. That means no wondering if a diaphragm or bladder is working properly, no inevitable replacement. And the best part? It meets code requirements.

With ease comes affordability. While expansion tank installations require several accessories that add up, for a thermal expansion relief valve, all you need is the valve and a drain line. This saves on parts and labor costs by speeding up service times.

These offer a longer-lasting alternative for your customers by replacing the bulky expansion tank, shut-off valve and fitting right at the water heater for an easier-to-install solution.

Expansion tanks are one of those items that tend to need replacing before other parts of the system. To address this short lifespan, look to a thermal expansion relief valve.

While expansion tanks have been the norm to keep thermal expansion from damaging plumbing systems, they come with reliability issues, extra installation costs and a lot of space. Thermal expansion relief valves give you the functionality of an expansion tank without its problems.

When it comes to keeping your customers comfortable, a water heater system plays a significant role. However, unbeknownst to the homeowner, not all parts of the system are efficient or reliable enough to maintain uninterrupted comfort.

The thermal expansion relief valve can replace a water heater expansion tank because it functions similarly. Both products absorb the excess pressure in the plumbing system created by thermal expansion. As plumbers know, the expansion tank equalizes pressure throughout the plumbing system by providing a space for hot water to flow into. Without an expansion tank, pressure would be distributed to the entire plumbing system, straining it and decreasing its lifespan.
