Hi all! I'm new here and am really digging this pool building stuff. Trying to add a little efficiency to my game plan. Found a large Hayward sand filter that came off a 25k gal inground, and now looking for a pump to drive it. 1hp, I'm guessing? One thing that concerns me is the 1 1/2" intex flexible hoses and plunger valves. Could I pick up flow by eliminating all of it and going straight pvc. Just plan on one suction and one supply line, both approx. 15ft. Any advice I appreciate, thanks!
