Please forgive the long story...
We have a 20 x 40 inground DE pool. There are two skimmers and one main floor drain. We installed the pool 19 years ago. Two years ago after losing water and having no pressure we replaced all the supply lines from the two skimmers and made the independent. They were previously joined by a Y connection. We had found that inferior flexible piping had been used and were crushed and cracked over time. We also changed the lining, filter and pump. The pump was upgraded from a 1 1/2 to 2 hp. The main drain seemed fine and was left alone.
For a year and a half all went well then end of last year the pump basket started collecting air. This happened after a half hour of great pressure and flow. Please be aware that since we have three independent supplies and two independent returns we closed each in every combination to see if it a particular line causing trouble. But the same result occurred. I was suspect of the supply valves we replaced because they wouldn't close properly. So this opening we replaced the valves again. That didn't help.
This opening the pool was dirtier than usual due to a late closing last season and the lack of pressure for the last month of the season. So my pool guy took the filter apart again and did a very thorough cleaning with water only. We put the system back together and noticed that the pressure held for three hours or so instead of a half hour.
Now I'm wondering a few things...
Since we replaced 2 of the 3 supply lines already AND when we isolate the lines we experience the same loss of pressure and basket of air AND the cleaning of the fingers helped could it be we need to chemically clean the fingers? AND is the 2 hp pump too much for the system? Or is it something else?
When we start up the system or bump it, it flows wonderfully. Then it slowly loses pressure and build air bubbles in the basket until we finally lose all pressure.
We would greatly appreciate any thought you might have. Thank you.
