I'm new to this forum and have never posted, so if I write something stupid, please forgive me.
For the past couple of weeks, I've been having to backwash my D.E. filter every 4 or 5 days. So, I thought my filter needed a thorough cleaning. So on Thursday someone came out and took the filter apart and thoroughly cleaned it, and the pressure was great (18 p.s.i.). This morning (Monday) I wake up and check the pressure and it's already at 30.
I haven't changed the type of D.E. powder I'm using, so I'm not sure what's going on.
Thank you in advance for any help!!
