Fix flush button and and leak under the sink

£100

Plaistow, Greater London, E13

Flush button needs to be replaced. I have done in the past. The old code was Grohe dual flush push button assembly - chrome 42268 000. I think the new code is 42204PI0. Tenants have also reported the kitchen sink leaking but it should be minimum effort as it only requires tighting. the the metal trim between the carpet and the tiled floor has lifted and is partially detached. Size is 1.46 cm. Probably needs to be replaced. Also the two bulbs of the kitchen extractor/range hood need to be replaced

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

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.
