Instructions

1. Simply slide the white nut over the pipe first along with the nylon washer, before the pointed black rubber washer
2. Make sure that the black rubber washer is pointing the thin end towards the white fitting you have yet to put on and slide the rubber on an inch or so
3. Push the rest of the fitting on so that the rubber joins up with the plastic fitting, you may then try and push the fitting with the rubber further down the pipe if need be
4. Finally bring the nut back and screw onto the rest of the fitting, compressing the pointed washer against the plastic to make a seal, then repeat the action for the other side and that’s it!

Details

Plumbing waste systems often involve a mixture of pipe materials and slightly varying diameters, which makes finding the right junction extremely difficult. Using mismatched or poorly fitted connections often leads to slow drainage or persistent, hard-to-fix leaks inside cabinets or under floors. Furthermore, many tee fittings create sharp angles that encourage hair and debris to snag, leading to frequent blockages that require professional clearing.

The McAlpine V1M eliminates these frustrations by providing a “Multifit” solution that adapts to your existing pipework. Because it is a swept tee, it keeps water moving efficiently, keeping your pipes cleaner for longer. The compression-based installation is clean and fast, avoiding the hazards of chemical adhesives. Whether you are dealing with modern plastic or older copper and lead lines, this junction provides a professional, leak-proof bridge that saves you time and prevents future maintenance headaches.
