I recently noticed that our outside wall has a wet looking spot around the faucet.

I tried looking in the wall at the pipe (from the unfinished basement), but

1. I couldn’t see very far because the hole is small (maybe could see an inch into the wall) and


2. I couldn’t see any condensation from what I could see.

Is there anyway to easily diagnose if there is a leak? There is a little bit of clearance around the pipe hole, but not much.

  There is a good chance it is wicking upward as long-standing water issues do travel northing in concrete to a degree. However the slight "crack" you have at the top makes me think this is at the faucet or higher. This does need to get fixed. You need to open things in basement, as any plumber would need that access.

  @DMoore thanks for the reply. Open things in the basement - the pipe goes directly in the foundation in the basement. Would a plumber be able to deal with the concrete or would this require someone "breaking" the concrete (not sure if this is the correct terminology) around the pipe?

I have seen copper pipe have small pin holes on several occasions. If your pipe is copper and in contact with the cement this may be the cause. The only way to repair is to replace that section of pipe. When I do this kind of repair I make sure to use thick wall copper because it will last longer than thinwall.

If you have access to the inside of the wall put up some cling wrap on the wall. Relatively quickly you should see where water is leaking. You can do this above, under, and to the sides of this faucet. If you wait too long to look at said cling wrap, it could all be wet.

Also it wouldn't hurt to dig a foot or two down on the outside and create a temporary well. If you do this three foot across on the outside and 18" down you can then view what the wet concrete looks like in a week or so. If it looks the same you know that your wet concrete is from an indoor leak for sure. If the wet area keeps traveling down to the well line it could also be excessive water at that spot on the outside being trapped there and wicking upward.

  Also you may get charged if there is water coming from outside and you ordered a plumber for something not plumbing related.
