In the last blog, we have discussed how you can inspect and correct water transfer pump problems you might have to encounter. There are some problems that can stop the progress of the most household chores and industrial processes. When the pump stops working and there is not any backup, it is important to locate the problem and treat the pump to restore the adequate supply of water. There are some issues in the pump that you can address on your own. However, it is not recommended if you do not know the pump from inside out. If it appears that you cannot repair the pump, calling a professional is a wise move. In continuation of the previous blog, here are some more water transfer pump problems.

Problem
Leak on well to pump suction
Inspection
If it is a shallow well unit, attach a pressure gauge on the suction side.
In case of deep well system, install the pressure gauge on the pump.
After closing the discharge line valve, apply 30 PSI pressure to the system using an air compressor. Now shut off the compressor. If the system is unable to hold the pressure, there is leakage.
Solution
Make all above ground connections tight. You might have to pull piping and repair leakage.
