Replace Leaking Kitchen Sink Waste Trap / P-Trap

£75

Bermondsey, Greater London, SE1

17th Aug 2026

I’m looking for a plumber to repair my kitchen sink waste pipe. The existing P-trap/U-bend has come apart and I haven’t been able to refit it correctly. I purchased what I thought was the correct replacement, but it appears the fittings/washers aren’t compatible with my existing pipework. Job required: * Assess the current waste pipe setup. * Supply any correct fittings/washers if needed. * Replace and fit a new P-trap/U-bend. * Ensure all joints are watertight and test for leaks before leaving. The sink is currently unusable as the waste pipe has come apart (see photos). Please let me know: * Your availability. * Whether you’ll bring any standard 40mm waste fittings that may be required. * Your total price including any small parts. Looking to have this fixed as soon as possible.

Great job and called out straight away to us - would highly recommend

Kitchen Leak Investigation and Repair Required I have a kitchen leak that is appearing between the laminate floorboards. The leak often occurs after the dishwasher has been running, particularly towards the end of the cycle when it is draining. I am looking for someone with plumbing experience to investigate the source of the leak and carry out any necessary repairs.

Yilnas did an excellent job. He quickly identified the source of the leak and repaired it efficiently. He was professional, polite, courteous, and clearly knew what he was doing. I would happily recommend him and would not hesitate to use his services again.
