Why doesn't the pump turn off when the water is shut off?

Close the water supply valve on the pump to check for leaks. If the pump stops after closing the valve, it indicates a possible leak causing pressure loss, making the pump run constantly. Common leak points include the toilet tank, where worn components may cause continuous leakage, and the washing machine, where deteriorated rubber O-rings may seep water. If no leaks are found after checking the house, its best to hire a technician for a thorough inspection.
If the supply valve is closed and the pump keeps running, the pressure switch may be broken or stuck, preventing the pump from stopping. A damaged pressure switch is a common issue, and its likely youll need to replace it.
Forgetting to close the bypass pipe valve can also cause the pump to run continuously, as water circulates without stopping. Closing the bypass valve will allow the pump to function normally.
If the impeller in the water pump is worn or damaged, it may not generate the required water pressure. In this case, its best to have a technician inspect it.

A water pump is a type of machinery whose components wear out over time due to usage. Therefore, it is essential to check its operation regularly to prevent potential emergency problems. However, if you choose a quality water pump like the automatic pump from Carina, you can have peace of mind
