Hello, please tell me about your water system.

Do you have a tank in the loft? If so, was this emptied while you had the water supply shut off?

Customer: replied 7 days ago.
Yese, there's a water tank in the Loft. I ran the kitchen cold water tap until it stopped, before changing the kitchen tap valve.

That shouldn't have emptied the cold storage cistern. Did someone have a shower or run a bath while you were working on the kitchen tap?

My hunch is that you have an air lock. Do you have hot water to the bath, or has that stopped too? Do you have a hot water cylinder, or a combi boiler?

(Please be aware that I'm about to be away from my desk for an hour or so.)

Ok, cancel the telephone call request.

No, noone used the water while I was working on it. Hot water is still working upstairs and downstairs. We have a hot water tank in the landing cupboard upstairs.

Ignore the telephone call requests; they are system-generated.

If it's not an air lock then there's something wrong with that tap, or the supply to it. So proceeding on the basis that this is an air lock, do you happen to have a wet & dry (or just wet) vacuum cleaner?


Customer: replied 7 days ago.
No.. I'm currently draining both water tanks, which is almost done.
Expert:  Tim Cooke replied 7 days ago.

Both tanks? I'm intrigued - what is your plan?

Customer: replied 7 days ago.
Is that the wrong course of action?

Hi Tim, what is your advice please?
Expert:  Tim Cooke replied 6 days ago.
The circumstances you’ve described wouldn’t lead to an air lock, logically, so there must be something else happening. I would eliminate the possibility of a tap fault as the next tap, by removing the handle and then unscrewing the valve. However, what type of bath tap do you have, and is there any valve that isika
Expert:  Tim Cooke replied 6 days ago.
...any valve that shuts off the supply to it?

Hello, how are you getting on with your cold tap?
