Frequently Asked Questions
What size DWV coupling do I need?
You need a DWV coupling that matches your pipe size. The most common sizes in Australia are 40mm, 50mm, and 80mm. Check the outside diameter of your pipe to choose the correct fit for a secure connection.Are DWV couplings suitable for pressure systems?
No, DWV couplings are not suitable for pressure systems. They are designed only for non-pressure applications like drainage, waste, and vent pipes. For water supply lines, you must use pressure-rated fittings.How are PVC DWV couplings installed?
PVC DWV couplings are installed using a solvent weld method. First, clean the pipe ends, apply solvent cement, then join the coupling and pipe firmly. This creates a strong, leak-resistant joint.Are these compliant with Australian plumbing standards?
