My Pump Has No Flow

Help for the hapless soul whose pump is not moving any water.

If your pool pump is turned on, but is not moving any water, it is important to figure out the problem as quickly as possible. The first step in troubleshooting this situation is to ask two questions:

1. Is the filter pressure high or low?

Typically when the pump is not moving any water, you will notice that the reading on the filter pressure gauge is significantly higher or lower than the normal pressure reading.

2. Is the pump pot full of water or full of air?

Normally, when the pump is fully primed, it will have nothing but water moving through it. However, sometimes when there are pump issues, you will notice that the pump pot has mostly air in it or is surging air and water through it.

Here is a table to help you to narrow down the problem:
