Recirculation Pumps and Expansion Tanks by Nashville Plumbers
Shorter waits, calmer pressure.
The overview

What it is, and why it matters.

In a large home the water heater can be a long way from the farthest shower, which means a long wait and a lot of wasted water. A recirculation pump keeps warm water moving, so hot water reaches the tap in seconds instead of minutes.

Expansion tanks solve a different problem. When water heats it expands, and in a closed system with a pressure regulator or check valve that pressure has nowhere to go, which can strain fixtures and the heater. A small tank absorbs it. We install both in Nashville homes and tune them to your system.

Good questions

Recirculation Pumps and Expansion Tanks: common questions

Does a recirculation pump use a lot of energy?

Not much, especially with a timer or demand control. It uses a small amount of electricity and saves water that would otherwise run down the drain.

Why does my relief valve drip?

A dripping relief valve can mean thermal expansion without an expansion tank, high pressure or a worn valve. We find the cause before we replace anything.
