Replace a Cracked Sewer Pipe (Before It Costs You)

Cracked sewer pipe. Forty-dollar part. Twenty-minute job. Or — a thousand-dollar shop bill. Your call.

Most RV sewer pipes are three-inch ABS. They crack from road vibration, freeze damage, or just age. Mine cracked at a slip-joint last spring.

Step one — cut the cracked section out with a hacksaw or pipe cutter. Two inches past the crack on each side. Step two — measure, dry-fit a replacement piece with a coupling on each end. Step three — primer, ABS cement, twist into place. Cures in two minutes.

If you've never done plumbing work — this is the easiest plumbing on Earth. No water pressure in these pipes. Just gravity. The worst that happens if you mess up — you redo it.
