A circulation valve regulates hot water flow within a recirculation loop, helping deliver hot water quickly while avoiding unnecessary waste. It works with a circulation pump to control direction and volume of flow, and can be manual or automatic with timer or thermostatic control.

Valves regulate hot water flow for faster delivery.
In a home with a recirculation pump, a circulation valve opens and closes to keep hot water available at fixtures while limiting energy use.
Pair automatic valves with timers or smart controls to match hot water circulation to daily routines.

Targeted valve controls can reduce hot water wait times and cut wasted gallons significantly.
Do circulation valves work without a pump?
They are typically used with a pump. Some retrofit valves can work with the existing plumbing loop, but a pump is usually required.
Can a circulation valve reduce energy use?
Yes. By controlling flow and timing, it can reduce unnecessary recirculation.
How often should a circulation valve be serviced?
Inspect it during annual maintenance or if you notice slow hot water delivery.
