I have bubbles in my pump strainer basket and when I shut off the pump there is tremendous back pressure that blows the lid off the skimmer basket. The only way to avoid this is to bleed off the air at the filter prior to shut down. I'm running the pump motor 24/7 for fear that it will not prime properly at start up.
I have replaced the o-ring on the lid and I have also swapped lids with a parallel unit running the in-ground cleanning system (no bubbles in this basket) but no improvement. I also just replaced the motor itself (not sure what happened but may have been related to a power failure) and changed out all the seals and gaskets on the pump in the process.
Water level at the skimmers is good but the skimmers seem to be tied to the cleaning system anyway so I think my pump is just drawing water from the main drain. There are some small drips of water coming from pipe joints after the pump - could this be the problem or where else would I look? I know this issue has been covered in other threads but appreciate any help that can be offered for my situation.
