I wonder if anyone can advise me on the following ?
I've recently had a flood issue in the flat and the bathroom is currently stripped ready for re-tiling. Prior to this flood there was a damp wall next to the shower cubicle and I had always suspected that the grout was loose or there was a leaking pipe in the wall feeding the shower (vertical).
The bathroom has been dried out and has sat dry for a few weeks now however over the weekend and given that I could now eliminate the vertical pipe as the cause as this is now exposed and no evident leak I thought I would run some water from the bath hose (which definitely has no leak as pipes are also exposed and have been using this to shower for a few weeks) into the shower tray for an hour or so to see whether any damp reoccurs which would then point at the tray/waste piping.
This is exactly what happened and the exposed (untiled) wall is now damp again at the bottom. I did a quick test with a water bottle close up and could see some water going in the side of the drain all the way round so this definitely needs to be re-sealed.... however I'm now concerned that maybe there is a leak in the waste pipes below ??? looking down the pipe from the drain grill (when taken off) I can see water and remains at a certain level.. does the fact that this is steady and not drying out mean that I can eliminate the potential of a leaking pipe ? Are there any other tests I would be able to do ?
This is a ground floor flat by the way and no access from underneath the floor..
Hi James the water you see when looking down through the grate is the water trap to stop odours, it does not tell that you have a leak or not. Fix the seal and let wall dry out.You can speed this up with a dehumidifier if needed, then run some water and hopefully all will be well.
