My pool has been given me issues lately. When in filter position it doesnt prime properly and I see a bunch of small bubbles in the pool. But when I put it in recirculation position it works without a hitch.
Eventually when it does work in filter mode it seems like there is no pressure going back into the pool. I check the skimmers and I dont see the water flowing into the skimmers the way it does when in recirculation mode. I read that bubbles are due to air being allowed into the pump from somewhere, but wouldnt it be the same problem in recirculation position?
Why is the pressure so much better in one position and not the other?
Seems like when the water has to go through the filter it gives me problems. BTW i recently had someone come out and clean the filter.
