Rule out the obvious causes of poor vacuum first. Make sure the water level in the pool is sufficient and air is not being sucked in through skimmer inlets. Add water to the pool to submerge the skimmers if necessary. Verify that the pump strainer basket and the skimmers are free of debris that may obstruct water flow.
Secondly, why does my pool pump loses prime when vacuuming?
Any air you might have in the vacuum hose will end up in the pump and it can lose prime if there is enough air. If you can, make sure all the air is out of the suction hose before connecting it to the skimmer plate.
In this way, why does my pool vacuum keep losing suction?
Verify that the vacuum hose is firmly inserted into the inlet port at the skimmer; then inspect the hose for cracks or holes. The skimmer filter is dirty. Pull out the filter basket and check for debris that may be interfering with water flow to the pool pump. Air is getting into the pump through the pump cover.
What is the most common symptom of a pump suction leak?
A suction side air leak shows itself most commonly by bubbles and splashing and frothing in the pump basket This indicates your pump is not getting the water it needs to function smoothly but, instead, air is getting into the system and starving or semi-starving the pump.
How do I increase the suction on my pool cleaner?
The first thing to do to increase the suction is to check for blockage and air leaks. If one of the skimmers does not suck, it would be necessary to remove the basket from the skimmer. Then check if there isn’t a flow control valve at the bottom of the skimmer, which would be almost closed.
