Hi there. I'm new to TFP but loving the wealth of information and sharing. I have recently installed 28 1'x10' Enersol solar panels for my 16x30 kidney IG pool. I use a 1hp single speed pump and assumed it should be strong enough to push the water about 50' away and up 20' and back but the jets are just trickling. I still have my older 3/4 hp Hayward pump and wondered if I could install it at the start of the solar line…perhaps with a ball valve to restrict the flow. Any thoughts? Unfortunately I do not have the technical expertise to measure gpm etc.
