I have 3 sheer descents ialong my pool. I believe 1 is 36" and the other 2 are 24". I have a separate intelliflo running these and it's using my skimmer which is 1.5" pipe. I am having a hard time regulating them to work the same. In general I just run my pump,around 1200 rpm and just use the 2 side sheers that are 24". When I'm in the mode and when I have guests over I'll crank it up to around 2600 rpm and all 3 will work considering my waterlevel is topped up enough. So when all 3 are on the 2 side it's are shooting strong while the middle one struggles to shoot water. I was reading up online and it seems that there was supposed to be valves right behind the sheers, problem is my lb guys didn't put them in and I can't get at them unless I open off the cement caps, any suggestions ?
