Water leaking from side of House

[petepp3]

Hi,
I have a worrying issue whereby when I use my upstairs shower (3rd floor) I have water leaking out of the external brickwork form the side of my house on the 2nd floor. I have removed part of the ceiling from ryje oom on the 2nd floor (as close to where the water is leaking) to get a better look of what is happening but it it bone dry.

Does anyone know what sort ofof tradesman I would use to help resolve the issue. I have asked two plumbers to have a look and they both say that they can fix the leak if I can get them access to it. Problem is I don't know who can make access.

Thanks
Pete

nasty one this as water travels and isnt allways coming from where its exiting

Could it be running from the waste pipe? I came across a case once where a rat had travelled up the soil stack and chewed a hole through a white plastic waste pipe just inside the wall.

none of your options are good imo
to eleiminate the possible leaks mean ripping things apart a bit ime afraid it can only be coming from the waste pipe or feed i know that sounds obvious but its that simple try running shower with hot only and see if it is hot or cold exiting via the wall

Has anyone used a plunger on a waste recently to clear a blockage? If the waste pipes are the push fit type a joint may have blown apart.

Unfortunately nothing has been touched.
The only was I can think to resolve is to have someone remove the bricks for the side of my house where the water is coming out and trace it back.

Coming from the 2nd floor? i take it you can see it from one of the ingoes around a window? is it coming from a level below the shower tray or bath?

I've had something like this before. it was on a new build kit house where the shower tray was cemented in and wasnt sealed properly. so the water just ran through the partition and out in a crack in the ingo. We could see it driping onto the window ledge when the shower was running.
