I thought of an idea to seal a leaking joint. First you would some how create a vacuum in the chamber posibly with a vacuum. Then you would put a lot of pvc glue around the leaking joint. And hopefully the vacuum would suck the pvc glue into the joint. Then of course you would let it dry for 24 hours.

it seems like you would be able to pake the PVC implode by doing taht if you have enough suction (whatever spelling) Maby you can modd one of thoes food saver vacs to use on it, ya know, convert that hose thingy for canning into something which you could get your PVC. If i don't make any sence, sorry.

Even a pure vacuum (0 psig) would only be a pressure differential of 14.7 psi. Since we're using pipe that's pressure rated to several hundred psi, I don't think implosion would be a problem. (Yes I know it'll be in compression instead of tension, but the walls are plenty thick to resist such small buckling loads.) Sounds like a good way to get some sealant to fill the holes, assuming your sealant is thin (read: watery) enough.
