My left water tap in bathroom sink has been running for some time now. My nephew was allegedly to have fixed it but I wasn't here and he was gone by the time I got home. One of the kitchen fitters put his finger or thumb over the tap and turned it on and it started to dribble again but now I am back to square one.
Is there anything I can do before I call him again. TIA I have tried thumb over the tap too but nothing.
Go to the hardware shop. Buy two tap connectors and the shortest length of hose they sell (unless you can spare 18 inches off the one in the garden). It will set you back about ten quid, which is money well spent if you would otherwise have to call the plumber every time it happens.
