Brownswood Park, Greater London, N4

I dismantled the pipes under my sink after fitting everything back together there is a leak. Specifically the leak is between the top of the ubend and the exit pipe. The problem is that the end of the ubend has a screw nut and the exit pipe is just a flat pipe so the connection isn’t tight enough

Fix a leaking bottle trap

£80

Acton Green, Greater London, W4

24th Oct 2025

Need a leaking bottle trap under sink fixed. Reattach or replace. Very short on space

Really happy I found Silva. He’s clearly very talented and skilled. What was thought to be a simple task of replacing a bottle trap, turned into a complicated job because of the structure and placement of my pipe work. Silva went the extra mile to disconnect and re attach the pipe and guided me on what he thought was best & not the easiest for him. Really pleased I’ve found him!! I’ve already booked him in for more work. Highly recommend!!

The ceramic discs in my old basin taps are broken and won’t stop dripping. Want to replace with new pair purchased online. There is also a slow dripping leak from the ubend behind the sink so I think this will need to be replaced too. I can either purchase or you can supply the ubend. Plumbers preferred.

Michael arrived on time and completed the task very quickly ! Lovely guy and nice to meet you. Thank you Michael !
