Attached is a picture of pool piping. Pool Builder has redone piping like 3 times and there is always 1 weak sheer. Using a Hayward Super Pump II 2.5 hp to run just the 6 sheer descents. Does anyone see a better way of piping it? Would a 3.0 hp motor work better? 2 of the sheers have levels to reduce pressure but not the other 4. Still not enough power. The pool picture shows 4 waterfalls but there are 2 more on planter. Please help me out. Thanks.
