New pool owner and I’m moving the pool equipment to a less visible area. Trying to diy this. Adding a H400FDN which I was told is overkill and also added the Hayward t9 salt system and the Hayward vs Tristar 1.85 pump. I currently have the s220t sand filter. My question is do I have enough flow to correctly fire my heater? Also I have 2” suction lines(skimmer and main drain) but 1 1.5” return line. So I’ll be going from 2” pipe until I get to filter which will have to go down to 1.5”, back up to 2 for heater then back down to 1.5 for the return. This sounds crazy to me. Should I worry? Should I get 2” Hayward flow valve to cut down on all the changes?any help is appreciated. Thanks
