Plumbing Guide

A recirculation pump keeps hot water waiting at the tap, and when it stops, the wait comes back. The cause is usually the pump, the timer, or a stuck check valve.

Hot Water Recirculation Pump Not Working: A Parker Fix

The pump

The pump motor can fail or seize, and it may hum without moving water. A hot, silent pump that does not circulate is often the problem.

The timer

Many systems run on a timer or a temperature sensor, and a dead timer means the pump never turns on even though it still works.

The check valve

A stuck or broken check valve lets the water flow the wrong way or stops the loop from working.

The air

Air in the loop can stop the circulation, and purging the air restores it. freezing winters and hard water are both common, and older homes often have aging supply lines In Parker, long runs to distant baths benefit most from a working loop.

The timer

A pump that is fine but never runs is often a timer or sensor problem. Checking the controls before replacing the pump saves money.
