i have 2 pumps on my pool, both Intelliflo connected to Intellitouch. One works off the drains and the other one is for the sheer descents using the skimmer. I have 3 sheer descents and even running the pump at full speed I can barely get the middle sheer to shout water out as my pool builder used 1.5" plumbing for the sheer rather than 2". My pool equipment supplier said i should use a Superflo VS pump and it will work, is this correct? Middle sheer is 3' and the two outer sheer's are 2'. Let me know your thoughts.
