Time to put on your thinking caps...
I got home last night to find a water trail on my garage floor. Closer inspection revealed that water was seeping up where the garage floor meets the house slab. This water seepage continued for a while but has since subsided. It was not raining and I can find no evidence of water around the perimeter of the house.
I have an atrium model (Sunnyvale) where the kitchen and family run are adjacent to the garage. I am stumped to find the likely cause as I can see no obvious signs (no hot water tank leakage, no apparent radiant heating leakage, no downspout problem, etc). I thought about a leak in underground plumbing but couldn't figure out why the seepage would subside if that was the case. Also, there has been no drop in water pressure.
I'm wondering if anyone may have encountered a similar problem. Thanks for any suggestions.
Does your dishwasher back up to the garage?If so perhaps the leak is tied to the times you use your dishwasher.If so it could be an under ground waste line that needs repair. If the problem doesn't happen again it could be that the last rains finally staturated the ground enough for the water to seep out of the joint in the garage floor. I guess it would be a good idea to have your radiant heating system checked for leaks if only to be able to rule this out as a source.
Thanks for the suggestions. In my case, the dishwasher doesn't back up to the garage and I haven't run it in days.
Today is the second day of noticable seepage. It seems worse around mid-day and subsides (dries) in the evening. I'll have to spend more time this weekend monitoring when the water appears and whether it coincides with water and/or drain usage. I guess my worse fear is that a water supply or waste line is leaking, requiring excavation and some creative plumbing repair.
I thought I replied to this but here goes...
Double check your water meter when you notice the leaking and make sure it isn't registering any movement, you hsould be able to hear the water going through it or the dial will be turning ever so slowly.
This way you can atleast rule out a plumbing problem.
Another Idea is that refrigerators will build up water in their drain pans from the condenser coils and sometimes they can leak. Any chance of that?
Also how muich water are you seeing?
Another timed source of water is a sprinkler system. I just recently had my waste lines replaced under the slab and the company that did it has the ability to video the waste lines from the vents on the roof.This might help eliminate that possability.
oohh.. I didn't even think about sprinklers...
Im wondering if its something in the radiants system and the warmth of the day is causing the water to come out and then as it cools off the water recedes.
