Puri Tech Generic Polaris Back-Up Valve Kit
Works with Polaris 180 280 380 3900 Pressure Side Pool Cleaners
If your cleaner is experiencing issues such as getting stuck on edges of the pool or having a hard time turning around, this could be due to a faulty back-up valve. Every 3 minutes the back-up valve will shoot water in the opposite direction that the cleaner is currently heading. This will help the cleaner remove itself from a stuck position.
