I was given a used pool heater that I am hooking up to my pool. I have two questions. Do I need to use schedule 80 pvc for the first 2 feet before and after the heater? Do I need to install a check valve?
Check valve- I only use liquid chlorine that I am adding by hand. I would think I do not need the valve unless I add a Liquidator or a in-line chlorinater.
The heater is a Raypak millivolt versa plus 151,000 btu. I was told to use schedule 80. The only reason I would not use 80 is because of the high cost. I can get the pipe and the parts.
Thanks for your help!
