Pump pressure is consistently low, around 5 psi. Although when I went to vacuum yesterday it was up at 30, but after backwashing pressure went back down to 5. I have a great swirl of water under the pump basket lid, but no swirl at the skimmer/return at the pool. Wife said pump was also very hot when she touched the pump after seeing the 5 psi reading last night when putting on the pool cover.
Took pump to local shop. No grinding noise, metal shavings, or unusual wear. Thinking an air leak between the pump and impeller, I replaced internal rubber washers and such ($25), hooked it back up, and still 5 psi. No leaks under the basket or impeller. I asked if there was a washer between the basket and impeller, but was told no.
Could this be something other than an air leak? How much water can be circulating at such low pressure?. I have a very simple system with limited piping above ground including this Pent-air Challenger pump attached.
Any ideas?
