I don't re bee the demensions but it's in ground, about 35 feet long and 20 feet wide. Just estimates. Deep end is 12 feet. This summer a new liner was put in, concrete was dug up and all new lines were ran to all the outlets and skimmer. I have a Hayward earth de filter, with brand new filter/fingers insert inside, for weeks we couldn't get it to run correctly. After a backwash , filter pressure would go up to 30 in 30 min.
finally I checked the 1 1/2 multi port valve which was broken and cracked. Two questions .
1) all last year I was constantly vacuuming what looked like sand in the pool. Could that "sand" be the earth going back into the pool due to having a cracked and broken multi port valve?
2) even after changing everything , backwashinf, rinse, ect ( remember the filter insides are all brand new) pressure still would go up to 30.
then I tried something out ,right next to my skimmer is a small opening the size of a return jet which also feeds water into the filter like the skimmer does. I closed that valve and am just using the skimmer to. Pull water into the filter. Doing this the pressure is now steady at 10-15. Can just keep that other port closed?or at least restrict the water flow from that, or is it needed?
Thnan, you in advance for the help.
