Plumber needed to do leak detection

[Know nothing]

I live in first floor flat. Flat below has a leak from ceiling. One plumber has fixed leaking trap beneath shower. Other plumber re-silconed shower trray. Leak persists. Plumber checked toilet cistern and bathroom. How can i find a plumber to do water pressure test on all my water sources to find the leak? No water being used for a week; flat below angry. Any advice really appreciated. Southampton area.

An easy way is to have a look in the flat below to see where the leak is coming from and try to pinpoint from there. Do you have a leak on any radiators?

Thanks so much for answering. My flat is all electric. In fact there are no radiators. I agree with your comments about looking from below flat's ceiling. This is the course of action we will take. Thanks once again.

Also, what I would ascertain is: does it leak all the time or just started happening, eg from rain?

Does the leak happen all the time? I do not think. Downstair's flat said it happened after a flush - indication of waste pipe.
Is it from rain? - I do not think so because it has rained once in last 14 days and the leak has stopped and started several times since.
The leak started Thursday 15 September.
If the leak is from my waste pipe will a plumber need to remove all floorboards, replace waste pipe or is there any other work that needs to be done?
Thanks

It depends on which waste pipe and where it runs, if it runs under floorboards it might be that they need to come up.

It may be better to investigate from bellow by removing a inspection hatch in the ceiling the flat below may or may not agree but at least they will know you're addressing the problem. Kop

What is your hot water system?

Reason i ask is that i have come across this in a flat where a fortic tank was not shutting off and the overflow had been routed under the floorboards.

This produces your intermittent symptons, with most leaks occurring in the mornings as no water has been run off to drop the level in the tank.
