FAQs
Is this fitting compatible with 32mm pipe?
No, this product is specifically manufactured for 40mm piping systems only.
Do I need to use solvent weld glue with this?
No, the push-fit design relies on internal seals and does not require or benefit from solvent weld glue.
Can this be used for hot water waste?
Yes, it is designed for standard domestic waste water, including hot water discharge from sinks and appliances.
What should I do if the O-ring looks damaged?
If the internal seal is damaged, the fitting should be replaced to ensure a leakproof connection.
Can I remove the pipe after inserting it?
Yes, push-fit fittings can typically be disassembled by pulling firmly while twisting, though you should inspect the seal before reusing the fitting.
Troubleshooting
Pipe is difficult to insert into the fitting
Ensure the pipe end is deburred and smooth. Apply a small amount of silicone-based pipe lubricant to the end of the pipe.
Minor leaking at the connection point
Remove the pipe, inspect the internal seal for debris or damage, ensure the pipe is pushed in fully to the seat, and reinsert.
