Using a Solvent Weld Coupler
Before fitting, check that the pipe and fitting are the correct size, clean and dry. Cut the pipe square, remove burrs, chamfer the pipe end where required and follow the correct solvent weld process for the system being installed.
Once solvent cement is applied and the joint is made, leave the connection to cure according to the solvent cement instructions before testing or putting the waste system into use.
