DWV PVC Repair Coupling is a two-piece repair coupling ideal for confined spaces and where it is not possible to replace the pipe. Only for use with DWV pipe or fittings. Complies to Australian Standards and is Watermark approved.
DWV (Drainage, Waste, and Vent) pipe and fittings are designed to drain soiled water in domestic and commercial applications.
N.B. all '90 degree' angled fittings are traditionally maybe noted/sold as "90 degree" but are, in fact, manufactured at 85-88 degrees , to allow for drainage purposes.
PVC pipe is the world's most popular medium for the conveyance of fluids. PVC has well recognized advantages of immunity to corrosion, chemical and micro-/macro-biological resistance, hydraulic capacity, ease of handling and installation together with toughness and flexibility.
DWV pipes and fittings are made from PVC-U. The pipe is rigid and comes in 6mt lengths.
The pipe is joined with it's mating fitting using solvent cement. See the installation guide for PVC-U. The jointing system in known as solvent cement joints(SCJ).
The joints do require a setting time of 24 hours to gain full mechanical strength.
Applications are:- Sewerage lines, vents, stormwater, grey and black water, sink and basin drains. It can be used as stormwater to increase water flow, as it shared many of the same fitting designs. There are adaptors in the stormwater range that allow for this.
This system can be used above-ground and underground. It can be exposed to sunlight, but it is not recommended over the long term.
A comprehensive range of fittings is available to complete the system, from 40-150mm.
The fittings are pale-grey.
Typically temperature ranging between 0Â° to 50Â°C.
They also comply with AS/NZS 1260â€œ PVC-U pipes and fittings for drain, waste, and vent applications.
