Rated 5 out of 5 by Strick from Water management system My pool sweep lost it's ability to move around the pool efficiently. The tail stopped moving even at a high setting. The pool store had it for a week and couldn't find anything wrong with it. I took it home and took the bottom off and plugged the water line back in. I turned on the water pump and saw the water management system (plastic manifold device) leaking dramatically. I ordered a new one and installed it, tried it out and now it runs like new. All for less than $30.

Rated 5 out of 5 by Pleased in Cowtown from It worked The 3900 Polaris lost its get up and go this past year, and even the tail no longer moved back and forth. Took it to a local well-known pool supply business who checked it out and said nothing was wrong. Being an Aerospace Engineer, I didn't buy their story. So, removed the bottom half of the Polaris, turned the unit upside down in order to observe the inside, and turned on the booster pump to see what was happening. The water distribution manifold was leaking/spewing water at four different locations. Clearly this was the cause of the problem, and reason for the pressure loss. Bought a new manifold from this company and installed it. Repeated the check I made to isolate the problem originally. Problem is gone! No leaks. The unit now has its spunk back and is behaving like new! The only complaint I have with this company is that they did not provide any shipping information so I could track the delivery progress. Was in the dark for about a week. Otherwise OK.
