I purchased a home here in sunny Sanford, Florida two years ago in 2011. It had been foreclosed and was a serious fixer-upper. There is a screened in rectangular pool in the back that is about 4 feet deep in the shallow end and 8 feet deep in the deep end, in ground, gunite, around 24000 gallons. This is the first pool I have owned.
The pool has three return systems on a three way valve, one part goes to a set of in floor pop up cleaners that seem to be missing the controller that makes them rotate, another goes to the eyeball returns close to the surface, and a third goes to a 1.5 inch outlet on the side near the top. I assumed this was for a pressure side cleaner, so after doing some research I bought a "The Pool Cleaner" brand pressure side cleaner. Works pretty well, but I can't get enough flow out of the outlet in order to make the thing climb the walls. I think the problem is that for some reason, someone plumbed in about 2 feet of 1 inch rubber hose in the section that goes to this particular outlet. It seems like this was done on purpose as a flow restriction.
Why would somebody do that? Is there some sort of pressure side cleaner that requires a significantly reduced flow rate that would make this make sense? I am planning on cutting out the part that is restricted and replacing it with regular PVC pipe like the rest of the setup. Are there any "gotchas" to doing this?
