    Pool heater hookup

    Hello all. Newbie here. I was just wondering about hooking up the 1 1/2 inch filter hose to my heater. I have the Hayward universal H150 which, in the manual, says it can accommodate 2" or 2 1/2". Then says to not have any other flow restrictions from the outlet other than inline feeders which I do have. I plan on pouring a concrete pad next spring and will then do all pvc hookup, but i have all the parts already needed to hook up the 1 1/2 and was curious if this would cause too much restricrion. Thank you

    It is perfectly fine to use 1 1/2 PVC hooked up to this unit. Use a 2" to 1 1/2 reducer, glued and inserted into the heaters union fitting.

    A word of caution: When working with gas and electrical you might want to consider a licensed contractor. Consider the value of your life and others around you.

    Just an FYI, depending on how you plan to install your heater and if you are using any valves, you can use a Jandy never lube valve as a reducer from 2" to 1.5". It's what I did with my heater.
