Fixing a fitting with PVC cement


If you have a broken fitting (overtightened it), can you just cake on a lot of PVC cement? Because it's going to be a huge pain in the ass it cut everything apart and put in a new fitting.

Btw, this is for 3/4" water lines at low pressure.

Oh - my main reason for starting this thread -- is there anything that will work besides PVC cement? Like JB Weld maybe? Or silicone calking?

Not likly to hold up. You would have to frill a small hole at the end of the crack to stop it from cracking more.
Far better to just replace it.
Always look for the PVC fittings with the brass insert if there's threads involved. Never had much luck with soild PVC. There made in two pieces and always seem to crack at some point.

These didn't even break at the seem, they were T's with 2 slip and 1 threaded and the middle blew out the same way in almost every one.

Going to have to replace -- 2 I saw were broken but 2 more ended up being cracked against the wall

What really sucks is that I put a lot of effort into getting them tight just so they wouldn't leak, never dreamed they'd all crack the next ****ing day.

Are these drain lines? Trying to picture where you would have used Tees like that.
If I get stuck having to use them I would have used teflon dope not tape.
It acts a lub as well as a seal so you do not have to tighten them so much.

PVC female threads are prone to break. Specially from over tightening. I have put hose clamps around the fitting before screwing in the pipe. It did work but was also a very low pressure line

Yeah, if I had it to do again, I would have ordered these and saved a ton of aggravation and money: http://www.bigalspets.com/slip-x-bar...FQWe4AodV2kA0Q

Can't find them locally though and don't really want to wait the 5 or so days it would take to get them.

If these are female PVC threaded fittings, they are not code legal. I think you know why.

I personaly never would have wasted my money on those. A simple brass barbed fitting never would have split.
What is it you really trying to hook up?

They are legal, if you thread a plastic fitting into it. Metal = not so much.

On a related note, I find it oddly humorous that the municipality here has their employees telling us that we need to start installing female pvc adapters onto their meter tailpiece assembly because the male pvc adapters always break.
