Hello, hoping someone here may be able to point me in the right direction. I have a Polaris 280 that stopped moving a couple weeks ago, but after some tinkering I got it to move again. Problem now is it moves very slowly and the water pressure is very low that come out of it, in fact so low that the tail doesnt move back and forth at all, it just drags behind it. The filter is free of debris. I finally noticed the other day that water is coming out of the pressure relief valve at a pretty high rate. Any suggestion what to do from here? Does the pressure relief valve need to be replaced or is there something else that needs attention that is forcing the relieve valve to act in such a manner? Appreciate any help!
