Ok, I'm in the middle of a remodel of my basement and am just getting ready to install a shower in this new space downstairs. Unfortunately for me, I discovered two nights ago that I have a MAJOR problem upstairs that is going to keep me from finishing the basement for a few days.
I walked out into the garage in the morning and discovered the ceiling of the garage looking like this:
As you can see, there is a massive water leak, and it is spreading all over the dry wall ceiling and leaking out at the seams. It's uncertain when this started...I would guess that it may have been a few days before the drywall was saturated enough to soak through. I called a plumber who lives close to my house and he came over to look at it. He told me "I'll find the leak, but I'll need to cut some holes. I'll probably start at the biggest water spot".
Not having great confidence in him, for some reason, I decided to jump in myself. I figured I could cut holes in drywall as well as anyone and since he said he was just going to guess where to start, I did the same. As you can see, I cut one hole in the ceiling. It was large enough for me to stick my head up there and see the drain and supply lines. I was also able to have the water turned on to see where the leak was. At this point, i was not sure which of the two bathrooms had the leak (also, whether it was shower, bath, faucet, drain, etc.) as the morning we discovered the water spots all had been used.
When the shower was turned on, i could see water spraying like crazy. I was then able to cut another hole in the ceiling directly under the trap for the shower with the leak (the one we use all the time of course!).
Here's a couple of pictures I took of the trap from underneath.
After looking at the drain up close, I discovered that it looked like the drain trap had become detached from the shower drain itself. Bear in mind, I've lived in this house for nearly 5 years and we use this shower daily! I have no idea why this would break now and how it have happened. To my knowledge, drains like this don't just "break".
Upon further examination, I went up and looked at the drain from the top. Here are a few top views... One of them is the drain itself. Another shows a small screwdriver pushing the trap away from the drain. This where the leak is. Dorry for the poor quality of some of these pics. My camera kept wanting to use the flash and it makes the picture look a little weird.
I have several other pictures that may provide a better view, but the site only allows 4 pictures in a post. Here's a link if you'd like to look further...
So, here's my questions....
#1 - any ideas why this would break?
#2 - is this straightforward enough to fix?
#3 - I assume I will need to tear out all my wet dry wall as it will likely grow moldy. Is that an accurate assesment?
Thanks for looking and thanks in advance for the feedback!!
