Hot Water Circulation Pump eliminates hot water inefficiencies by using logic-based controlled hot water circulation.

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.

The purpose of a hot water recirculation system is to provide you with hot water faster, so if you find yourself waiting for hot water when you turn on the tap, there could be something wrong with your system. Here are a few potential problems:

As a leading low pressure check valve manufacturer, U.S. Valve supplies check valves in a wide variety of configurations and materials. We are known for our ...

This 1/2 inch lead free brass water pressure reducing valve is designed to reduce incoming water pressure to protect plumbing systems and reduce water consumption for commercial, industrial and residential applications. The easy maintenance assembly consists of a replaceable seat module, solder union inlet and outlet connections and a bypass feature to control thermal expansion pressure. The temperature range is 33 to 180 degrees F (0.5 to 82 degrees C). Suitable for up to 300 psi (20.7 bar), the pressure range can be adjusted from 25 to 75 psi (172 to 517 kPa) with the standard setting at 50 psi (345 kPa).

A hot water recirculating pump is supposed to make your access to hot water more convenient, not less. If you notice one of these signs that your recirculating pump isn’t performing at its best, call Maeser today. One of our experienced technicians will get you back up and running as soon as possible.

Spirax Sarco US Pressure Reducing & Surplussing Valves can reduce or maintain steam pressure accurately, reliably & economically for the application.

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.
