Bizarre tap leak

Didn’t really think this was suitable for the mech tech section - a question for you plumbers out there…

The cold tap in our bathroom leaks. But is completely bizarre. It only leaks when there is a pressure drop in the system and this is beyond my understanding of all things plumbing….
For example- flush the loo and the tap starts dribbling. Loo system fills up, and it stops?

I just don’t get it?

yours,

Confused from the narth.

 

Under pressure things are tight ,lose the pressure and you lose the tight fit of any seal

 

Thought you might have offered to send him some PTFE tape

 

Two reels should do it. And plenty of Boss White

 

Think I’ve got a roll of Extra Thick PTFE tape in the garage.

Do I just wrap it over the end of the nozzle do that it stops dripping?

 

Yep. That’s what a professional would do.

 

Yea but I don't have any

 

Your all off my Christmas card list, and you need to go and sit on the naughty step

 

Thanks for all your help.

I’ve turned the water off at the mains and it has fixed the problem

 

Excellent. Now charge yourself £80 callout

 

It’s your boiler i know they are doing deals at the moment at the wholesaler.

there can I call myself a plumber now

 

20% off a Worcester, I heard.

 

You need a whole tube of clear silicone over the pipework too..

 

He's undercharging.... my tennant decided to call the emergency plumber last weekend.....just got a bill for £288 ... that was to turn power and gas off to boiler and stick a " condemned " sticker on it.
Dam expensive those stickers.

 

This is why plumbers are all cruising round in BMWs, smoking Cuban cigars.

 

Bet you can’t do that super push-fit pipework like Jivester. Took him hours…

 

Boiler..!!!

You have graduated straight to BG heating engineer....
