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.
