Driving from California to the East Coast. My alignment was off so I took it to an alignment shop and as I left the shop I bottomed out and busted my sewage holding tank pipe. So I fixed one problem and now I have another. It's the big 3 inch pipe and it's got a hairline fracture in it. Is there a way to repair it without taking it into the shop and having them replace the whole pipe? Is there some way to fix it from within the pipe? Some kind of repair glue or patch kit? Thanks! John

My first move would be to grab a small can of ABS cement, and run a big bead of it, right over the crack. If that fails, there are kits made to repair broken plastic pipe.

Any existing crack in it will be prone to propagating and any repair leaving the crack in place should be considered temporary. Permanent fix is to replace that section of pipe. It's not that hard to do if there is reasonable access.

If you have access, stop drill the ends of the crack. Use JB Weld to repair the crack. Cover the repair with a strip of Eternabond. It's not a pressurized system, the repair will stop any leaks.It's nice to replace the broken pipe. Sometimes it's just easier to do a good repair, especially if you're on the road.You may not want to bother replacing the pipe when you get home.
