Constant leak coming from under our bath that we need some help with.

£120

South Harrow, Greater London, HA2

13th Jul 2026

​ We have a constant leak coming from under our jacuzzi bath tub (upstairs bathroom) that we need some help with. It doesn't seem like an overflow issue—it's running all the time and leaking downstairs into the kitchen, so we suspect it's a pipe leak as shown in the videos and probably needs to be replaced.Let me know if you can help and when you might be free. Thank you.
