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!

Details

Standard white plumbing fittings stand out drastically against dark modern interiors or exterior brickwork, ruining the look of a clean bathroom remodel. Furthermore, repairing a broken waste pipe frequently reveals confusing size differences between various plumbing brands. For example, some manufacturers produce 1.5-inch nominal pipes that measure exactly 40mm externally, while others measure 42mm or 43mm. Because rigid solvent glue fittings require an absolute perfect millimeter match, standard couplers will frequently leak or fail to slide on entirely. Therefore, trying to join two slightly different pipe brands usually results in a weeping joint that slowly ruins your flooring.
