Was hoping to get feedback on a filter / pump question. The builder just fired up the pool yesterday. I have a 53' Sta-rite Dura glas DE Filter. He put some DE and fired it up with my 1 hp sta-rite pump. The pressure read 18 psi right out of the gate, now from what I read it probably will run high real quick from all the construction debris and new plaster. When we turned the pump to the low speed the pressure dropped to at or just below 1 psi. I am still getting excellent flow out of the two returns on low speed. So my concern was is this right that on low speed the psi is that low in the filter. Should i be concerned at all or since I am getting flow out of the returns this indicates everything is working and my extra large filter is just doing a great job and is not overworked.
Your comments will be very welcomed !! Thanks all !!
