How to Prevent Freezing of Water Pumps

As we enter November, it begins to snow in many areas in the north, and some rivers begin to freeze. Did you know? Not only living things, but also water pumps are afraid of freezing. Through this article, let’s learn how to prevent water pumps from freezing.

Drain liquid
For water pumps that are used intermittently, the pump body is easily cracked by freezing if it is placed outdoors for a long time in winter. Therefore, when the water pump is out of service for a long time, you can close the valve at the water inlet and outlet, and then open the drain valve of the water pump to drain the excess water out of the pump body. However, it will need to be refilled with water before it can be started the next time it is used.

Warming measures
Whether it is an indoor or outdoor water pump, it can be covered with an insulation layer in a low-temperature environment. For example, towels, cotton wool, waste clothing, rubber, sponges, etc. are all good insulation materials. Use these materials to wrap the pump body. Effectively maintain the temperature of the pump body from external influences.
In addition, unclean water quality will also make the water more likely to freeze. Therefore, before the arrival of winter, we can dismantle the pump body and do a good job of rust removal. If possible, we can clean the impeller and the pipes at the water inlet and outlet.

Heat treatment
What should we do if the water pump has frozen?
The first priority is not to start the water pump after the water pump has frozen, otherwise mechanical failure will occur and the motor will be burned. The correct way is to boil a pot of boiling water for later use, first cover the pipe with a hot towel, and then slowly pour the hot water on the towel to further melt the ice cubes. Never pour hot water directly onto the pipes. Rapid temperature changes will accelerate the aging of the pipes and even cause rupture.
If possible, you can place a small fire pit or stove next to the pump body and pipes to use continuous heat to melt the ice. Remember fire safety during use.

Freezing of water pumps is a common problem in winter. Before freezing, you can avoid freezing of pipes and pump bodies by taking measures such as warmth and drainage. After freezing, you dont have to worry. You can heat the pipes to melt the ice.
