The feed line to my Polaris cracked under the concrete pool deck about 2' back from the pool edge. It was in a sharp elbow and may have been to settling, high pressure, or poth. I know the PVC-40 can take some high pressure but there may have been a weakness in the elbow to begin with -- it was a hairline fracture at a high-stress location (but it emptied about 2" of water over 6 hours!).
So it's repaired but i want to keep the pressure in that supply line as low as possible. Why can't I regulate the pressure at the pump instead of using the restrictor discs and pressure relief screw? That way the supply line will be at the lowest workable pressure to maintain the 30 rpm wheel speed and reduce the possibility of future leaks.
