    Polaris 360/380 Relief

    Recently had some issues with my polaris pool robot. Not sure of the model, either a 360 or 380. Had a low pressure condition and thought it might be the relief valve so I replaced it. turns out I had a leaf stuck in the turbine/blocking the jet. once I got the leaf cleaned out, started up the pool cleaner, and my new relief is blowing water like crazy, which it did not do before. So, I guess I got the wrong relief? Anyone know what the model/part number of the higher pressure relief valve is? Thanks

    crusemm:

    The P/N for the Pressure Relief Valve on the Polaris 360 is 9-100-3009 according to my owner's manual. For the Polaris 380, the P/N is 9-100-9002.

    Well, I I ordered one of each. I I think I got the wrong one last time, so I will try both and see which works.
