If you like puzzles and mysteries then you will love this.

My wife calls me this afternoon and tells me we've got some flooding in the basement. She needs to learn how to relax... I mean, there isn't anything you can really do to stop whatever is letting the water in, so why freak out? Anyway, I had some ideas of where it might be coming from so I wasn't too concerned. I get home and I go downstairs to inspect the damage. Try to imagine the lay of the land with me... You walk down the stairs and immediately to your right is the laundry room. Floors are concrete and dry as a bone. A little further down to the right is a bathroom. The carpet in front of the bathroom is definitely flooded. To your left is a tiled dining area that is dry. Also there is a family room that is mostly dry. Directly in front of you is a bedroom. That left wall is shared with the family room. Can you imagine it? I'll upload pictures in a minute and illustrate.

The Puzzle: None of the outside walls are wet. There are only two walls that are the outside walls and they are in the bedroom. The edge of the carpet is dry by the wall. I pulled back a corner and the concrete below is dusty dry. Also, the water did not go under the wall to the family room. The carpet along the wall in the bedroom is dry, so if the water came from under the wall then it is only flowing one way. The water in the family room would appear to be coming from under the wall because it goes all the way to the edge and then appears to be expanding from there. The carpet in front of the bathroom is the wettest, but there is absolutely no water on the floor of the bathroom at all. There is dust behind the door and even a missing tile on the edge of by the carpet. It is totally dry.

The Mystery: The mat in front of the shower in the bathroom is absolutely drenched. When I tapped it with my foot it actually splashed. There isn't a drop of water anywhere else on the floor. The mat is not a low point of the bathroom either. The floor is very level if not even slanted a little down. The mat is at the highest point of the fairly level floor.

Quandry: I just sucked 22 gallons of water out of the carpet. The carpet was not wet around the edge of any of the walls except the family room. It was not wet around the edges of any of the furniture in the bedroom. There are no drips in the ceiling and there is no water running down the wall. Where did all this water come from?

My thoughts... I think the shower overflowed. I think something caused the drain to back up and the water went over the edge. It went just high enough to go over the edge and the mat soaked it all up. I think the same thing can be used to explain the water in the hall and bedroom. I think they might have carpeted over a drain without closing it off first. I don't know where it is, but that is my guess. Unless my wife ran the hose in through the window and managed to soak the carpets without getting one drip near the walls then I think that is the only solution. Any thoughts on that?
 
Have you had a real gulley washer of a rain in the last day or so?
About 30 years ago we got some ridiculous amount of rainfall, like 15" in less than 24 hours. The city sewer and storm sewer lines couldn't carry away all the water and we had water back up through a floor drain in our basement. If I remember correctly, it was tied into the drainage tile around the house and and all the rain water from that tile was what was causing our problem. I was home at the time and bought a 1/2 hp pump and pumped the water from the floor drain into the back yard. It probably ran for at least 24 hours before I caught up with it.

Now days houses have to have a check valve installed between the house and the sewer to prevent something like that happening. It is code in most places, especially if the city backwashes the sewers. It seems rather stange that the bathtub was allowed to overflow without anyone knowing. Is there a toilet in that bathroom? If there is you may want to check around the base for any seeping, or on the back of the tank to determine if it has a hairline crack. Hopefully, this is just an isolated event, but it would be best to check the fixtures just in case.

In Jngr's case, I think he may have a shower with a low rim base for a drain. It would take a lot of water to overflow a bathtub, but not much for a shower base.

When we had our problem, I don't think a check valve would have made any difference. There was no place for the water to go. It didn't need to back up from the main drain line. It was like continuing to run water into a full bucket.

The house is 30 years old, so it may be that what Charles happened is the case. It has been raining pretty hard the last 2 or 3 days. We had a truckload of snow today in fact. Winter just doesn't seem to want to end around here.

The water in the bathroom could have only come from one place and that's the shower. I'm having a technical difficulty getting the pictures off my camera, but here is one from my camera phone. The toilet is pretty far away from the shower. That mat was soaked to the limit.

I like Charles' idea. That is proabaly what happened. Now I just need to figure out where the hidden drain is so I can cap it off. There are enough houses in this neigborhood that are built the way mine is that I'm sure I can find someone who knows where all the drains are.
 
That would have been my guess too, except for the fact that the floor is entirely dry. There are dust bunnies on the floor behind the door of the bathroom. There is no way that 22 gallons of water flooded across the bathroom floor and into the hall and bedroom without leaving a drop of water on the bathroom floor. The water had to have had two seperate sources to do this. The mat in the bathroom was probably soaked from the shower drain. The carpets in the hall and bedroom were soaked from some other source. I put a dry towel in the shower just to test my theory. If this happens again then there will be a wet towel in the shower as evidence. We don't go downstairs much for anything. If I hadn't left a bag of skittles on the couch then my wife probably never would have walked across the carpet and discovered the water. She was just on her way down to do some laundry when she discovered it.
 
Maybe one of the vents for the fixtures needs to be caulked again. They are vented up through the walls, so if water is entering from the roof and following down the walls, that may be causing the isolated flooding as well. We had a recent occurance of this in our shop bathroom. The roof is tin, and i guess the 25 yr old caulking contracted a bit and was no longer keeping water out. This led to some warped sheetrock along the lower portion of the bathroom, and occasional flooding during heavy rain. Just another option, I don't know how your fixtures are vented, may not be the case for you.

Sorry, I don't know how I got bathtub, i thought that sounded really strange. The only time a checkvalve helps is if the city sewer backs up, this prevents waste water and sewer gases from going back into the house. This doesn't really work if you have any outside gutter or drainage systems that enter the system prior to the check valve. (which is illegal in most places in CA at least). I guess it all depends on your area and your individual connection.
 
But there isn't any water near the walls. The water seems to have orginated right in front of the bathroom and bedroom. The entire inside perimeter of the bedroom is dry. The floor in the bathroom is dry. The only wall that has any water near it is the inside wall of the family room. There is a bedroom behind it and no pipes in the wall. I'm going to ask some neighbors tomorrow where the drains are. I called my insurance company and they said if it was a backup from a drain that was out of my control then it would be covered under my homeowners insurance. Flooding is a little different situation, but this isn't something that came in from cracks in the wall or faulty plumbing on my part. Something screwy happened here. The fact that the drain got carpeted over is irrelevant. It would have just backed up even more water out of the shower if it couldn't get out of the drain.
 
Here are some better pictures so you can see a little better what I'm talking about. I'm not too bent if the carpets are ruined. We haven't gotten around to doing the basement carpets yet. Upstairs was enough for one year. lol That mauve and that flower pattern has got to go...

You can see the little missing piece of tile under the door in the bathroom. Its dry as a bone. If water had gotten anywhere near the door then it would be wet there. I just don't understand it....
 
I'll give my dad a call, if anyone knows plumbing it's him. I'll try my best to get you a good answer and a few ideas where to look.
 
It musta been that creepy chick Samara from that movie The Ring!

You say it was really cold, perhaps it was ice that somehow got into the house and then melted?
