Typical newbie question I am sure but I cant figure this out. I have a Hayward DE filter. 2 year old pump (not sure what size). What is going on is that I always bleed off the air after starting the pump. I get all the air out of the filter. But maybe 2 hours later I go back and the Filter has air built back up in it. not alot but I can bleed it off for maybe 4 or 5 sec until water comes out. I assume this is from a leak somewhere but how do I figure that out?
Thanks for the help!
