PVC drain pipe leaking at joint, 2 part epoxy last?

harleysilo

So after finally finishing the installation of the kitchen sink, I noticed that where the left side drain and right side drain tie into the main there is a small leak. It's right at a joint in the pVC where a angled T is. I bought some 2 part epoxy, mixed and smeared around the bottom of joint where leak was, waited an hour and tested. No leak.

My concern, will it last? The product is sold at lowes and adverstised as a marine epoxy, but shows pvc pipe on package.

It may, or may not, last. Now that you have epoxied it, the only way to disconnect it is cutting the fitting out. If it was a joint leak, it may have been a sealing gasket that was broken (or forgotten to be installed). Silicone caulk would have been a better choice since at least you could have removed the fitting later if necessary. Good luck.

I guess I should have been more specific. It is all glued pvc pipe, no dissassembly possible. To fix it would be cut and remove regardless...unless the expoxy will hold.....

Thanks for the clarification. Usually, if a drain is going to leak, it starts right away. If it is not leaking now, it probably won't. Even if it does, silicone could still be applied. Just watch it for a few days. Drainlines (without a disposal) are not under much pressure so I would think you are safe.
