In autumn and winter, the weather is cold. Many users will use a lot of heating equipment for heating, and then they need to install a hot water circulation pump. Regarding the hot water circulating pump, many users will have many questions. Most of them do not know how to install it after purchasing. Below I will briefly introduce the installation steps of the hot water circulating pump, hoping to help the majority of users during installation. Install the hot water circulation pump close to the faucet to save plumbing.

1. Before installation, please check carefully whether the running path of the pump is impacted. During operation, check whether there are hard objects (such as rocks, iron sand, etc.) in the flow channel of the hot water circulation pump, so as not to damage the flow direction parts of the pump.

2. During the installation process, the weight of the pipeline should not bear on the pump, otherwise it will be easily damaged.

3. Before installing the pipe, please rotate the rotor part of the water pump, there should be no friction or jamming. If so, the pump should be separated immediately to check the cause.

4. For the occasion of pumping head, it should be equipped with a bottom valve, and there should not be too many elbows in the water inlet pipe, be sure no leak water or air, which will affect the pumps’ performance.

5. Prevent impurities from entering. If the flow path is blocked in the pump, a filter should be installed before the inlet.

6. For the convenience of maintenance and safe use, please install a regulating valve on the inlet and outlet pipes of the pump, and install a pressure gauge near the inlet. For high lift pumps, install a check/one way valve before the outlet gate valve to prevent water hammer. Check valve to deal with power failure such as sudden power failure, to ensure operation under optimal working conditions and prolong its service life.
