LESLIE: Alright. Now we’ve got Lynn in Colorado who’s got a tricky, leaky shower. Let’s see if we can help her find the leak in shower.
LYNN: I had a plumber come out once and he said that the pipe and the bottom where it comes out of the shower doesn’t always hook up right. So he siliconed it and it didn’t leak but now, once in a while, it’s leaking again. Of course, it’s upstairs so I see it on the ceiling. And I’m wondering, is there some kind of a liner you can put down the pipe like they do for sewage lines that go out?
TOM: You talking about the supply pipes or are you talking about the shower stall?
LYNN: I’m talking about the stall – the drain pipe.
TOM: Do you have – is it a tile shower pan or is it like a plastic shower?
LYNN: Yeah, it’s one of the insert ones.
TOM: Those pans can develop cracks in them and you have to figure out where that crack is to help find the leak in shower. One way to try to figure out at least how high on the pan the crack is is if you block the drain of the pan and fill it up with water and see if it leaks. If it doesn’t leak, then the pan’s fine. Then the next thing you have to do is move up with your sort of analysis and now you’re going to get into the seams of it.
If you’ve got existing caulk, what I would recommend, as a first step, is to remove that caulk using caulk softener. And that’ll allow you to strip out everything that’s there and start clean with some new, good-quality bathroom caulk that’s got a mildicide built into it. And I would just caulk very carefully every single seam and also around all the pipes and the faucets and the fixtures, where they come through. Because, sometimes, you get direct leaks where water fills up in the pan and leaks. And a lot of times, though, with showers, you’ll get leaks when the water bounces off your body, hits one of those seams, works its way in behind the wall and down.
So, I would take out the existing caulk, recaulk it and check the shower pan for leaks. And somewhere in that analysis, you’ll probably figure out what’s going on.
TOM: Alright. Good luck with that project. Thanks so much for calling us at 888-MONEY-PIT.
