Hi, I recently purchased a house with pool which I'm just bringing to life after winter shut down. Pump is running fine and water flow appears normal. However I noticed the pressure gauge was reading 0 and I'm sure before winterisation it was reading around 5 - 7 psi. System has a Lacron LSR18 side valve filter with multi port valve attached. I tried doing a backwash and noticed that hardly any water was visibly in top of filter - i mean like a dribble!! When turned back to normal filter the water is visible and as far as I can tell flow rates are ok.
I'm thinking that maybe the filter medium is all clogged up or something, but before I attempt stripping filter down would appreciate any suggestions.
I did change valve for a spare - still no reading
Yes, I did turn pump off before moving multi port valve
