I'm searching for a plumber for EC4M, City of London. The water in my flat has been very low pressure for a few months now. It suddenly just changed overnight with no leaks or changes to anything. I used a wet vac and brought it back to a useable level but this week things got worse. The dishwasher and washing machine are not working and say no water and all the taps and flushes are only just trickling now. Are you able to help? Please quote and let me know your availability this week if you can.

Repair toilet leak, existing report available

£200

Richmond, Greater London, TW10

27th Oct 2026

Initial repairs remediated the leak which was coming from the flush inlet at the top of the toilet. However, works undertaken by the plumber has now worsened the toilet leak. Recommendation is there could be a fault with the waste pipe or alternatively a crack in the toilet which i believe in unlikely given that the toilet has been functioning ok for the past 7+ years with no incident of damage. We have been told the original installation is slightly faulty but again this has not been a problem until now. Detailed report for further explanation available.

Great job - fixed the leak which another plumbing company could not. Very happy with end result. Thanks

Bathroom Waste Pipe Leak – Repair Required

£250

South Bromley, Greater London

26th Oct 2026

Bathroom Waste Pipe Leak – Repair Required There is a leak from a bathroom waste pipe caused by a visible split in the pipe. The bath needs to be removed to access and replace the damaged pipe, which may involve removing tiles. The job includes repairing the leak, reinstalling the bath and restoring all tiles and fittings. Photos attached. I’m a school teacher and off work all this week, so I’m flexible with availability. Please only make an offer if you can complete the entire job and follow through with arrangements.

I can see why this man has 5-stars. Unbelievable service and attitude. Happy to do whatever it takes to get the job done. Just when I was about to completely abandon this site he has single handedly changed my views. Really impressed and 5-stars across the board and offered to come over to look at it if there’s any issues in the future. Took 3 trips to get materials and all done in 4 hours. A credit to AIRTASKER

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

Leak in the kitchen

Chingford Green, Greater London

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.
