Leaking Mains Water

[skewett]

Hoping someone can suggest a workaround for this problem.

I have a leaking tap which is connected directly to the mains supply (just moved in to a new house) and I want to try and get it sorted as an outside water supply. Trouble is we live 800+ metres from the mains cut off and I'm on a water metre so I don't ant to waste money by doing the obvious shut off and replacing the whole tap. I'm assuming that I'd have to waste a fair amount of water in the pipe between the supply and my tap.

No water leaks when the tap is shut but when I open it water leaks out from the where the white nut connects into the grey fitting.

I'm assuming that it may easily be sorted by some PTFE or a new washer in that tap fitting but I'm thinking if I unscrew it, then the water is going to be coming out at some force. The water pressure in the whole house is very high.

Any suggestions greatly appreciated.

You wont loose the 800mtrs length of pipe full of water with the Stop tap shut, it needs something to push it out, even if you live downhill from the stop tap.

If you did loose it all, 800mtrs and its a 32mm pipe , that's around 0.5 cu mtr at a cost of approx £1.

Replace the tap complete or you'll be paying to do it again later.

And if that hose is supplying a tap for use outside it needs back flow protection.

first replace that plastic rubbish with a proper tap, include a double check valve, remount the whole lot so the blue pipe is vertical and not stressed, use a squeeze off tool to cut off the water to do the job, no waste at all. That tap you have will eventually, sooner rather than later just fail and then you will waste some water.
