How do I remove glue from a coat?

PVC pipe glue - how to remove to fix leak?

  • I have a small leak in a PVC pipe joint. When I noticed the leak at first, the glue was totally worn away and the pipe joint was free. There wasn't much wiggle room as the rest of the piping was pretty sturdy next to it. So, I coated it like usual with pipe joint glue, pressed it together the best I could, and it seemed to hold. Then, I recoated all around the joint again after it dried. Problem is, there was still a little water in the pipe, and it pushed through while drying, to still create a small drip through 2 little pinholes. I tried to recoat again with no luck! The small amount of water is for some reason making its way through and making little pin hole drips. So, now I have a sealed joint with glue, and I don't think I'll stop the leak with more glue added to it. I don't want to have to cut away the pipe for several reasons, mainly b/c the T that leaking is very had to get to. I want to somehow remove the glue so I can start over and re-glue this joint. I used some stuff called Rain N Shine, thats supposed to be able to glue while a little wet, but I guess NOT. So, is there a product that will dissolve this glue on contact so I can remove and start over w/o cutting any pipe away? Can I heat it until the glue softens? Next time, I'm going to use better joint glue and make sure the pipe is completely dry. Or, 1 more thing - is there a super-strong glue or something I can seal this joint with while its already glued to stop these small pin-hole leaks? Will JB weld work? Something like that meant for PVC pipe leaks??? Thanks a million......

  • Answer:

    you are correct in the fact if you have a heat gun (not hair dryer) you can heat the joint and twist it apart. do not heat too much as the pvc will get real soft and loose it's form. I have done this a couple of times and know it works - so if anybody tells you different, their wrong - it works! as far as a super strong glue? just make sure to use the prime recommended and glue. the primer actually starts the chemical reaction so that when you glue and stick it together it holds.

You may try JB weld or one of the putty type epoxies, but you won't get the PVC glue apart. It isn't exactly a glue. It causes a reaction of the PVC and the joints actually melt together if everything is clean and correct.

Shut the main water supply off and open all of the faucets to release the pressure on the line. Dry it with a blow dryer for 10 minutes then apply the JB weld. Give it 2-4 hours to completely cure then close the faucets and turn on the main water supply SLOWLY! Ryan

Just a thought. Maybe dry up the crack as best you can Wrap some white teflon pipe thread tape around the crack and then re-coat it with the pvc glue. I myself have not tried this, but who knows.

If you know exactly where those pinholes are, you can try a compound you buy at a hardware store and add the old remedy for quick repairs....cover it with a broken piece of garden hose or some other rubber patch and tighten it good with a hose clamp, the kind you see on radiator hoses in a car.. Plumbers don't call this a permanent repair, but you can see if it works. It's cheap and easy, so you don't have much to lose in trying.
