The spider gasket in my multi-port was bad and causing a steady trickle leak out of the backwash exit pipe. Yesterday, I replaced it, and everything was working great, leak solved. Today I rotated the lever to do a backwash. After the backwash and rinse, I put it back to “filter” and it was...

I had a small leak as evidenced by moisture forming at the base of my pump motor, so I replaced all of the gaskets and the shaft seal (Pentair Challenger). I have reassembled it several times because of a steady leak from the housing and seal plate. No amount of tightening the band clamp seems...

I have been getting my liquid chlorine at Wally World for just under $6/gal before tax, but the season is over, and it’s all gone meaning I have to pay slightly more for bleach that is 7.5% vs 10%. I am considering switching to Zappit 73%, which allegedly doesn’t have CYA. Which at $240 for 50...

I started this thread awhile back. The pool docs came over and we discovered that the whole plastic ring part of the diffuser (that the o-ring attaches to) was gone, and probably always had been. A new diffuser doubled the strength of my output at the eyeball ports in the pool, and helped with...

I dealt with some air leaks in the union on top of my impeller housing for much of last year. I had regular priming issues, but got to where I had it pretty much under control. About 2 weeks ago, the priming issues returned and would not go away. I ordered new parts to replace the union, and...

My Pentair Challenger Pump has sprung a leak and nothing I have done will fix it. The leak is in the socket union that attaches to the top of the front housing. I've tried caulk and then I tried sealing it with teflon tape just as a last course, but I think I need to just replace it. The...

My main pump is on a 2 pole 20 amp GFCI breaker. Current flows and everything for the pool works properly, but if you press the TEST button when the CB is on, it should trip it. It doesn't. I think it's not providing the GFCI protection that is required. My plan is to replace the breaker...

I have a polaris 280 pool sweeper. It has a backflow valve that pulls the sweeper out of corners, effectively putting it in reverse for a minute or so every so often. I just discovered it has ruptured and cracked the ring that seals it all together for the second time in as many years. Any...

In March I replaced a 4 month old pump motor, that wasn't under warranty because of water damage. I had noticed a leak from the same place that my new one has now started leaking from (see the picture), but it was a slow leak and I didn't think it would really have anything to do with the...

I just bought a replacement motor for my main pump. I was going to put the new shaft seal in when I noticed a little wear on the seat where you insert the seal. These are two shots of it. Should I replace this or is it fine? My main concern is the small chip in the 1 o'clock position in the...

I noticed the pump was making more noise than normal, and called my supplier for ideas. They had me take a picture of the shaft, which was corroded because the counter-clockwise screw that holds everything in had come loose. This invalidates the warranty on my 4 month old pump. It still...

The breaker box that powers my timer has a few ants in it. The timer box was crusted with electrocuted ants. I came home from a five day work trip to find my pump not working, and this is clearly the problem. I took the timer apart and cleaned the ants out, but this didn't help. I tried a...

I came home yesterday to find my main circuit breaker tripped, and there was a distinct odor of hot metal/ electrical burning. I replaced this pump shortly after I bought the house. Looking back at my records it looks like the date was November of 2015. The replacement had all the same stats...

I've been doing the TFP method for about 2 months now, and as a result, have largely stopped going to my pool supply store. Recently they sent a bunch of coupons for free stuff and I needed a new sight window for my filter, so I figured I'd see how their numbers compared with mine. I was just...

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...
