Finding a leak from my shower
I've been trying to find where the water's getting out of my shower
cubicle. Access is poor, I have a little gap up the side and I can see the underside of the tray, but it's too tight for me to actually reach in there. The problem is that water drips from somewhere near the wall, it's dripping through the floorboards and wetting the plaster of the ceiling below. It doesn't do it every time, and I can't figure out what makes the difference. There are no cracks in the tray, and it doesn't look like the water is escaping either from the pipes, the fittings fittings or the drainags system. This really only leaves the tiles, the grout and the silicone sealant. The lowest two rows of tiles above where I believe it's coming from were loose, so I took them off. Sure enough the wall behind was wet, so I dried off and re-stuck the tiles, re-grouted and applied silicone along the egde of the tray to make sure. All seemed to be well. No more drips. Until today. The lady of the house had a big shower (why does it take so long to wash hair?) and there's a proper little stream coming down into the kitchen. It seems to be coming from the same place, but my new grouting and sealing looks fine. The adjacent bit of wall is not pristine, there are hairline cracks in some of the grouting, but it doesn't look bad enough to allow that much water through. So how invisible can a gap be and still let water out? I really don't want to re-grout the whole damn thing. Also, and tips for pinpointing the leak would be appreciated (I'm thinking fluorescent dye or something). TIA John |

Try directing the shower spray onto it with someone weatching from below and wait for the shouts of alarm as water comes through! |

Thanks for the replies. I got the hosepipe in and did some carefully directed spraying. The problem was partly that it there's a massive lag in the system so I had to be very patient, not my strong suit. Turned out that some hairline cracks in the grout were letting water through, as expected. Going to scrape out any areas that look even slightly dodgy and regrout. Cheers, John I have a nasty way of sealing tiles to china..I uses a bead of silicone first, then tile and grout over it. Looks better than silicone alone, and won't let water through even if it does crack. |

If for some reason this fails to produce the desired shouts of alarm, just direct the showerhead straight at them. Always works NT |

It turned out that there was a big crack all the way down the corner, where the plasterboard side had settled away from the brick wall slightly. I guess it's likely to happen again as a result of further small movements. It had been covered with silicone, but as you say, grout looks much nicer. I'll keep an eye on it! |
