Solvent PVC pipework (black waste) is similar to the downpipes from the guttering outside your home and is usually a cheaper alternative to the more heavy duty pressure pipe.
Apply solvent cement to both surfaces to be joined. Insert the pipe into the fitting to its full depth. Allow a few minutes for the cement to set before handling/ moving. Solvent weld pipe and fittings are strong and durable and provide a permanent fitting when secured with Solvent Cement.
