Getting ready to remove my SuperFlo pump and replace it with an Intelliflo pump and I have to redo some plumbing.
The new pump suction line sits an inch higher than the pump that is there now and I plan to keep the original pump as a spare for the winter. My plan is to setup the plumbing so
I can switch the pumps without much work so I am going to buy some flexible 2" PVC and unions to be able to disconnect one and connect the other if needed. From what I have read the suction side of the pump needs a straight run 5 times longer than the diameter so that means I need
a 10" straight run of pipe feeding the pump. My pool builder connected my pump union right to the 90 degree elbow off my valves so I know it's not as long as it should be. I suppose the straight run of pipe going into the pump is to help with cavitation, but not sure why it needs a straight run into the pump.
The flexible PVC will only be about a foot long or so on the suction side and maybe 3 or 4 feet long feeding the filter.
Question for those that know, would this be a correct way to be able to disconnect one pump and hook up another without having to redo plumbing in the middle of the winter ?
Thanks
