I am new to pool maintence and have purchased an automatic pool suction side vacuum.  I installed per the instrcutions to my skimmer but the vacuum does not move.  When I place my hand at the diaphram of the automatic pool vacuum, I dont feel much (if any) suction.  However, if I place my hand directly into the skimmer above the suction hole, I feel a "strong" suction.

Requires Pump Power: ≥0.5HP/1000gallon


Troubleshooting Done So Far

I searched a few guides here but am unsure of what the issue may be.  Below is a summary of what I have tried thus far assuming I have a low pressure problem:

1. I cleaned the Skimmer Basket

2. I cleaned the 2nd Basket attached to the front of the pool pump

3. I cleaned the Cartridge Filter after the pool pump

4. My return jets (2 of them) appear to be operating at full power

5. I do not see any obvious leaks around any of the visible PVC pipes around the pump / filter area.


Any help would be appreciated!
