Can I fix a main drain line leak myself?

Probably not. Unless you have a pressure test kit, a jackhammer, and experience with hydraulic cement, you’re looking at a bad time. Your options are calling a leak detection service and a pool plumber, or rerouting the drain above ground — neither is a DIY weekend project. Paying $800 to a pro is cheaper than the $2,000 in concrete repairs you’ll cause trying to save $800.
