PVC DWV Slab Repair Couplings are designed to connect or extend pipework at floor or slab level where there may not be enough exposed pipe to use a standard coupling.
Socket x Into Pipe versions have a female socket at one end that fits over matching DWV pipe, while the reduced spigot at the other end fits inside matching nominal DWV pipe. This allows a connection to be made where only a short section of pipe remains above the slab.
Flanged Socket x Into Pipe versions use the same connection arrangement and include a flange to provide additional support at the floor or slab surface.
Into Pipe x Pipe Size versions have an into-pipe spigot at one end that fits inside matching nominal DWV pipe and a pipe-size spigot at the other end. The pipe-size spigot has the same outside diameter as matching pipe and fits into a compatible female socket fitting.
Connections are joined using PVC priming fluid and suitable non-pressure PVC solvent cement. This is known as a solvent weld joint, or SWJ.
PVC DWV pipe and fittings are suitable for use in stormwater, sewerage, wastewater, vent, and other non-pressure applications.
