How to Fix a Plumbing Supply Line Leak

Hi, I’m Mark Donovan from homeeditionplus.com and today I walked down on my basement and I stumbled upon this, so what you’re looking at here is some water. It’s obviously been leaking in on the basement floor and basically there are two possibilities where this could have been coming from. One thought was that it was coming in from a foundation due to the heavy rain that we have overnight or it never had an issue with any type of water in the basement for any type of rainstorm. My second thought was that I had some type of plumbing leak, well it wasn’t too obviously repair was that there was no water spraying here in the basement.

As I investigate the plumbing in my basement, I noticed that near the edge of the wall, directly underneath my kitchen cabinets, the one in the supply lines look like it have been leaking at least slowly at one point. As you can see, this moisture on the wood suggesting I have a leak somewhere probably up in the kitchen area.

So what I discovered when I went up into my kitchen area that that supply line count directly underneath the kitchen sink and where it was leaking was right around this nut on this valve assembly that supplied the hot water to the kitchen sink. Now this is a fairly common type of leak. What happens is that people turn on and off this valve to maintain the kitchen sink by itself; this nut can come off a little bit loose. As you can see, around the nut, there are some mineral deposits that suggest that this nut has been leaking at some point and indeed it was up until a few minutes ago when I lightly tightened the nut on this to stop the leak.

Another reason why this types of leaks can occur is that particularly in this hot pipe, the continuous heating and cooling of it can cause the nut to slightly loosen over time and again water begins to slowly drip from the nut. The way to resolve this type of supply plumbing leak is to simply use your question wrench and tighten up the nut approximately of a quarter of a turn and that should usually do it.
