Polypipe Waste Solvent Weld Reducer - 50mm x 40mm - White

This reducer uses solvent weld jointing, which creates a permanent chemical bond between ABS pipes and fittings.

You will need ABS solvent weld cement and cleaner. These are typically sold separately.

No, this reducer is specifically designed for solvent weld ABS systems and is not compatible with push-fit or compression fittings.

Bio Cote is an anti-microbial technology integrated into the material to help inhibit the growth of microbes on the surface of the reducer.

It is used in residential plumbing to connect a 50mm waste pipe to a 40mm waste pipe, commonly for sanitaryware or kitchen appliance drainage.

Initial set typically occurs within minutes, but full cure and system pressure testing should wait several hours, following the solvent weld cement manufacturer's instructions.

Ensure the solvent weld cement was applied correctly and joints were held firmly during setting. Check if the pipe ends were properly prepared and if sufficient curing time was allowed. If leaks persist, the joint may need to be cut out and redone.

Verify that you are using the correct pipe sizes (50mm and 40mm). Ensure the pipe ends are not deformed and are cut square. If the pipe is slightly out of round, try re-rounding it before attempting to join.

Ensure the cement is within its shelf life and has been stored correctly. If the cement is too thick, it may be old or have been exposed to air. Follow the cement manufacturer's instructions for application.
