Hi All! It's been a while since I posted here. I wanted to share my success story in case it might help somebody out of a bind one day.

Last spring we had to buy a whole new pump and filter system. I was still using the original one that came with our pool and it was time to replace it. I went back with the same one I had, a Waterway II 200 SF Pro Clean Cartridge Filter. The old one had served us well for 10 years. When it arrived it looked totally different, it was the "new and improved" style. No problem, we hooked it up and had a great summer.

Fast forward to a month ago. We uncovered the pool and started it up. Water was blowing out of the filter housing like a fountain. I took it back apart and discovered it had 3 significant cracks in it. One was about 8" long and the others were 3 to 4" long. You couldn't see them from the outside but they were very noticeable from the inside. I don't know how I missed them when I put them new cartridge in. I can only assume the brutal winter we had caused it, even though we completely drained it last fall when we closed the pool. I thought the warranty might cover it but I was wrong. I got no help from Waterway other than offering to sell us a new one, which I declined.

So, I decided before I invested in a new filter I would at least attempt to repair it. I didn't have much faith that it would work, but since it was probably going to the dump anyway why not give it a try?

JB Weld Plastic Bonder (3770 PSI) did the trick. The pump has been running nonstop for 3 over weeks and it hasn't leaked a drop of water so far. I can't say it will last forever, but so far it has held up great.

Edited to add: I plan to replace the filter. I don't consider this to be a permanent solution.

I would strongly recommend that you replace the filter.

It's under pressure and cannot be made safe.

It might not leak, but it could explode at any time.

The time that it's most likely to explode is when you turn it on.

When you turn it on you're standing right next to it.

Many times at turn on, there is air in the filter, which greatly increases the danger because the air can get compressed and can propel sharp shards of plastic or large chunks of filter.

Don't take the risk. Replace the filter.
 
I plan to replace it soon fairly soon. I'm probably going to buy a sand filter next time, I'm still undecided. There's no danger to me when I turn it on. It's inside a cement enclosure and we have the power switch for it inside our home.
It has kept the pool from turning into a swamp, which was my main goal.
