If you turn on the cold water and get hit with hot water instead, you may actually have a problem with the bypass valve that’s a part of your hot water recirculation system, rather than the pump itself. The valve is designed to close and keep the hot water in the pipes once it’s up to temperature. When it cools down too much, the valve opens and the pump pushes the water back into the cold lines, making room for freshly heated water in the hot pipe. If you have hot water in the cold side, on the other hand, the valve may actually be staying open when it shouldn’t be.

A hot water recirculating pump is great for convenience and comfort, as it means getting hot water faster when you turn on the hot tap. For homes with on-demand or tankless water heaters, this is important, as it can otherwise be a little bit of a wait before the cold water clears out of the pipes and the hot water reaches you. When a hot water recirculating pump starts having or causing problems with the system, though, it can become more frustrating than anything else, especially if you don’t know what to do about it. Here are a few signs there is a problem with your hot water recirculating pump, and what to do about it.

Like with most things, a lot of noise coming from your hot water recirculation pump isn’t a good sign. Once again, there are a few different things it could be.
