Hi all. I've added 19 10ft enersol panels to the roof second storey about 100 ft of pipe total run from filter to solar header. My inground pool uses a sand filter and with solar off and just gas heater effecting return the psi is 18. Once solar is on it hits 23-24psi. Guy at pool store says its no prob but enersol states it shouldn't run over 20psi. Flow from jets is fine and panels heat well. Should I add a pressure relief between the solar uptake and return or do you think it's ok? Also it appears the panels do not drain once the actuator switches them off. Is this a concern?
Thanks in advance
