    Milky Explosion after turning on pool cleaner

    I have been a TFP follower for about 3 months with excellent results so far. Today, I tried firing up my pool cleaner, which as best as I can tell is a Polaris of some sort. I have used it 2 or 3 times in the year I have owned the pool, and I can't remember if this happened before, but I think it might have. Anyway, after some huffing and puffing, the pool cleaner cranks up, and all of the sudden a very milky discharge is coming out of the pressure valve right at the quick connect.

    As you can see, it looks like someone dumped 30 gallons of milk in there. I assume there's some sort of gunk in the pipe, that my infrequent use is allowing to build up in there. We don't get many leaves in the pool, so I just don't feel like I have to use the polaris that often. Is it something to worry about? FWIW, in the 15 minutes since it happened, the cloud is 20% smaller, and I'm pretty certain that the filter will clear it out completely, but I'd still rather know if something is badly wrong that needs attention.

    Thanks,
    Chappie

    Everything is just a wild guess without current test results. Did it come from the return pipes and not the robot itself?

    Update:

    The cloud stays there as long as the back-up pump is on, though it does seem to be getting smaller. If I turn the backup pump off, the normal filter gets it cleared up within a couple minutes.

    Welcome Chappie!

    Just out of curiosity, what kind of filter do you have? If it's a DE filter, some could have entered the pool and settled on the floor and perhaps the bag isn't fine enough to catch it. Hence the cloud.

    Take a few minutes to fill out your signature. It helps us a lot.

    It appears to come from the pipe that pumps water into the cleaner itself, though no milkiness seems to be coming out of the cleaner. As near as I can tell it is coming out of the bypass valve at the quick connect. The cloud forms down-wind of that at any rate. What tests would be useful here? I can run them all if you think it will help.

    The milkiness is nearly instantaneous, and it's not a matter of the bag on the pool cleaner, if that's what you meant.
