After Turning Off The Water At The Stopcock Under The Sink ...

how long before water should no longer come out of the taps?

LB. One thing I would expect them to look for (when the drainage people arrive,) is where the "soil stack" is located.

As I mentioned on a previous thread of yours, "vertical" flats often have a pipe that runs internally from the top flat right down to the bottom one, and out into the drain underground. It carries all the waste and waste water jointly (shared by the flats.)

They'll know where to look ;o)

Thank you Builder I have been told the Stack pipe is behind the wall where the gurgling comes from. I'm assuming that is the same as the Soil pipe? Yes what you say applies here with only two flats above me and they both say they don't have a problem. Why is it just me that is having the problem? Why can't my neighbour the other side of the gurgling hear it or any of the above flats? Do I take it the water is not draining away if it is coming up into hallway? If someone can remind the site to use to put a picture on here I'll do so.
All ?s sorry.

Thanks LB. Yes, that's the soil stack. I remember mentioning it on your previous thread.
Even from here, I would put money on that being the source of the gurgling.

A partial bung-up at the foot of a stack is not uncommon.
Possibly... the loud dripping is water from upstairs landing on the blockage, the sound being amplified through the soilpipe.
Also possibly... the gurgling is the sound of trapped water seeping away very slowly.
I would trace the outlet of the stack to its nearby manhole, and rod backwards right into the building and through the obstruction.

This is exactly what drainage investigation people would do.
Fingers crossed.
While you're here... had you turned the wrong valve under the kitchen sink (see previous post on this thread.)?

Also........ there is a solid blockwork wall between you and your neighbour. That's why they don't hear it. The stack is most likely just in your flat, and simply boxed in either with thin plasterboard or plywood.

Thanks for explaining that all sounds good to me TB, ie it's not through something I have done so is not my fault therefore I don't have to pay. If that turns out to be the case I might attempt to get reimbursed for the money I have spent on plumbers. I hope they hurry before it damages my flooring and any other parts of our little block. No re the stop tap, it was my neighbour who asked me to do it but I think he'd gone out for a meal by then. I was so fed up I just switched it back on again, had a shower and opened a bottle:-)

Sorry mamya just noticed your post at the bottom of the last page. Thank you. I've got everything crossed.

Relief. The problem has been moved from a noise problem to a leak problem and so is now considered urgent! So it is LOL. Yep! A drainage/stack pipe investigation will take place on Monday afternoon.
It had better (she mutters).
