Do I need to install a bottom valve when using the car wash water pump


The use of car wash water pumps is expected to last for a long time, and there will be no problems during use. However, the opposite is true. Over time, there may be some small troubles. How to avoid them, maintain them during use, and is it useful to install bottom valves?

Usually, the car wash water pump does not need to install a bottom valve because it has a check valve, also known as a one-way valve, at its inlet. After the water pump stops, the liquid inside cannot return to its original location, so not installing a bottom valve will not have a significant impact on it.

If the bottom valve is installed on this basis, the use effect will be better, because if one of the one-way valves is damaged and the bottom valve is functioning, there will be no idling phenomenon, which is beneficial for the use of the car wash water pump and can also extend its service life.
