Low water pressure in a pool is one of the most common issues. The cause of this problem can come from a number of sources. In this guide/video, we explain how to identify an air leak on the suction side of the plumbing and how to repair it.
Before you start looking at the suction side plumbing, we recommend ruling out some of the common causes of low water pressure. First, make sure the filter is clean and that the diverter valves are open, so water can easily flow to and from the pool. Clean out the skimmer and pump baskets. Check the pump lid o-ring. A bad o-ring can cause the pump not to prime and impact water flow. Lastly, make sure the water level is half way up the skimmer door opening.
Note: We used an irrigation pump in this guide but the same principles apply to a pool pump.
