Plumbing Cutting and Connection Recomendations

Pro plumbers share their favorite tips and tricks for cutting and connecting pipe and more. Despite the name, lots of plumbers never use plumber’s putty. It damages some types of plastic and stains surfaces such as natural stone. Plus, it tends to dry out, crack and allow leaks. Silicone caulk is a safer, longer-lasting sealant in most areas where you might use plumber’s putty.

Dope Everything
Thread sealant (aka “pipe dope”) is formulated to seal threads. But it’s great for almost any connection, even if the threads don’t form the seal. Use it on compression fittings, ground fittings and rubber seals. Because it’s slippery, it allows connections to slide together correctly for a good seal. And, if you use a type that doesn’t harden, disassembly and repair will be easier years later. Some types of dope harm plastic parts, so be sure to check the label.

Cut Pipe with a String
It’s almost as fast as a saw and fits into tight spots where saws won’t. To give the string a starting point, cut a shallow notch with a file or hacksaw blade. Then simply pull the string back and forth to slice through PVC or ABS pipe.
