Get a good seal in threaded pipe joints by using sealant. Plumbing projects and repairs are often made up of various fixtures and fittings joined to pipes. Each joint is potentially a leak just waiting to happen. To get a good watertight seal it is important to fill the spaces between the threads of a pipe and the threads of a fitting with some type of sealant.
Two thread sealant options are:
- Pipe joint compound - a spreadable sealant that is brushed or in some way spread onto the threads of a pipe.
- Teflon tape - a tape that is rolled onto the threads of a pipe.
Both options help improve the seal created at a threaded joint when used correctly.
