New pool owner and new to the forum. We have a 27' ABP, for the first few weeks the water pressure on the return was awesome, put your hand infront of it and it would push it away, now its become about as much as my garden hose. Ive cleaned my cartridge, resealed all my hose connections. my PSI on my cartridge is at 20psi (Although I thought the first few weeks it was around 15psi.) I pulled my pump apart to make sure there wasn't anything in the impeller portion all was clean.
What route should I start looking at first?
