Instructions

1. Simply slide the black 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!

For thicker waste pipes such as iron the plastic insert may have to be carefully cut out in order to install

Details

Standard white plumbing fittings can look jarring if your pipework is exposed or if you have a modern, dark-themed bathroom interior. Beyond the aesthetic issue, joining different types of waste pipe—or finding a fitting that accommodates pipes with slightly varying diameters—is a notorious plumbing headache. Using mismatched connections often leads to slow drainage or leaks. Furthermore, many tee fittings create sharp angles that encourage hair and debris to snag, leading to frequent blockages.

The McAlpine V1M-BL solves these frustrations by providing a “Multifit” solution that adapts to your existing pipework while maintaining a clean, professional black aesthetic. 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 secure bridge that looks as good as it functions.
