Thank for the reply ! Are you using restrictor/directional eyeballs in your returns? YES What is the make and model of your filter? Hayward S210T Have you cleaned your salt cell recently? I have done some pressure test: Filter in recirculate mode, no eye ball, no SWG , pressure = 6.5 PSI Filter in filtering mode, no eye ball, no SWG , pressure = 10 PSI Filter in filtering mode, no eye ball, with SWG , pressure = 12 PSI Filter in filtering mode, with eye ball, with SWG , pressure = 15 PSI So the eye ball add 3 PSI and the SWG add 2 PSI The SWG can run with a minimum flow of 11 GPM, i actually run it when the pump is at low speed. I guess i could install a by-pass valve to limit the flow going to the SWG You want minimize the pressure on the panels. Were you planning to put the entire flow through the panels? On the installation guide , the entire flow pass through the panels, but since i will install a diverter valve to turn on/off the collectore i could adjust it to limit the flow. I have post a request to SmartPool to get the min and max flow as well as the head loss. Didn't have a response yet ...

I want to install a solar collector on the roof. I have bought the SmartPool SunHeater model S425P , 2 collector 2’ x 20’ According to the sunheater manual , no vacuum breaker is required The actual layout is: skimmer -> pump -> filter -> salt system -> pool return which size should be the PVC pipe to go to the solar collector ( 1.5” or 2” ) ? Pool : Above ground 15’ Pump : Hayward 1.5 HP, model Ultra-Max sp2915 Salt system : Intex Total height to the roof 15’ , distance 9’ (from the filter to the wall) Actual pipe size is 1.5" Pressure at the filter: With the salt system: 15 PSI Without salt system : 12 PSI Should I install the solar panel before or after the salt system ? Is it ok not having a vacuum breaker ? Thank !
