Wondering if/how bad a water in the basement problem I have.
Some history: 5 year old house, walkout basement with no previous water issues. This spring they've been doing a bunch of sewer work in our neighbourhood but afaik that's completely unrelated to anything. Also this spring we noticed one of our outdoor faucets has somewhat lower pressure than the other 3. Not super low, but noticeably worse. I checked the valve is and it's fully open and don't see/feel any water there. Pictures of the connection:
In the second picture you can see some staining...we had some ants in the spring and I sprayed around the foundation. That's the only spot where it stained which I thought was odd but didn't think too much more about it.
On to the issue. We have a table top ping pong table we'd been storing in the guest room which is on the other side of that hose. It's been in there since end of May-ish. We took it out to set it up and noticed some water on it. Pics:
How it was stored
Picture of the water damage (not super obvious in the picture but it's noticeably raised in the circled part.) There were drops of water on it on the two halves on the sides that were facing each other, other half of table has similar damage in the same spot.
The carpet directly beneath the table felt slightly damp and smells mildewy. I checked around the baseboards, under that book shelf, the bed legs, etc. and can't find any other water. There's a small bathroom on the other side of the wall the bookshelf is on but again I see no water in there or around the toilet.
Basically I just cannot figure out how the water got there. That room doesn't always get much air circulation (my kids have a tendency to close the door whenever they're down there and sometimes it doesn't get reopened for a couple days) but again I don't see any water/stains anywhere else in the room.
So far I've dried the carpet, brought in a dehumidifier and aired the room out a bit the last couple days. Should I call in a plumber/professional? Is there something else I can do to figure out if there's a problem/how big it is? Any advice much appreciated!
