No, this is a push-fit fitting. Using glue can actually damage the rubber seal and make future maintenance difficult.
This is specifically designed for underground drainage systems and is not rated for use in internal high-temperature waste systems.
No, you should only use a proper silicone-based lubricant. Petroleum-based greases can degrade the rubber seal over time.
The 2.5-degree offset provides a slight 'fall' in the pipework, which helps gravity maintain water flow and prevents blockages.
Yes, standard 110mm drainage fittings are generally compatible across different manufacturers, provided they follow standard UK dimensions.
Ensure you are using sufficient silicone lubricant and that the pipe end is cleanly cut and chamfered.
Check that the captive seal has not been dislodged during insertion and verify that the pipe is pushed in far enough.
To install, ensure the pipe is cut square and the end is deburred. Apply a generous coating of silicone lubricant to the pipe end and the rubber seal. Push the pipe fully into the socket, then withdraw it slightly (approx. 5-10mm) to allow for thermal expansion during temperature fluctuations. This fitting is compatible with standard 110mm underground drainage pipework. For care, keep the area around the joint clear of debris during backfilling to avoid stressing the joint connection.
