I'm new to the forum and a first time pool owner. We purchased a home last October that has a 22 x 37 inground gunite pool, 4 feet at shallow end and 9 feet in the deep end. I just installed a Polaris 360 and am having problems. I had to add an extra 8 feet of hose so it would cover the entire pool. The pool has three returns but no valve to regulate flow independently. The problem is that the cleaner keeps returning to the shallow end and floating on it's side on the surface. I've adjusted the valve, the float, removed a float from the feed hose and even tried adding some weight just in front of the float. I've also noticed that the sweep hose assembly only trails along behind the cleaner with the scrubber trying to come to the surface.
Does this sound like a pressure problem? I wasn't able to get the correct RPMs of the drive wheels, but I haven't tried installing the eyeball regulators yet since the existing retainer rings have been covered with concrete or gunite and I will have to chisel them off apparently.
Any help will be appreciated. Thanks.
