    Lots of water blowing out polaris 280 pressure relief valve

    My polaris 280 has a lot of water flowing out the pressure relief valve at the wall connection. Is that normal? I haven't pulled the hose off to see if the blue disc is in there or not.

    It could be normal. Is it a lot more than it was previously?

    Mine blows a significant amount out of that valve, i made it so my valve points down, otherwise it was pushing a column of water up beyond the water line, kind of bubbling up (without the bubbles).

    I read that it's normal from a few others posts. I'll check my RPM's and make sure they're 28-32 today.

    Reviving the thread - looks like there are many of these observations about that relief valve for the Polaris cleaners - I have a 380, and after some years, the water coming upwards from that relief valve has increased, with that came a slow down of the cleaner.
    The booster pump is the same and I have taken apart, from the hook up at the outlet in the pool wall, to the cleaner itself with replacement of the bands that move the wheels.

    In one of the many threads about this subject, someone, after replacing the relief valve twice, took it out and put a plug - Polaris will of course say extreme and may damage the internals of the cleaner, but the poster claims that it brought the cleaner to its original speed and performance.
