If you can shut off the water coming INTO the house first, it will make the repair more secure. Of course, the main water input valve is usually either rusted open, or needs a special wrench from the county or the plumber. But depending on what's feeding that pipe, you might be able to shut off the water upstream before your start the repair.

I have photos uploading now. I believe what you're saying is exactly what I'm going to do. I am concerned because there is some damage to the wood under there too.

This water line is coming off the hot water heater into the house. Therefore using the cutoff of water to the water heater has allowed me to continue to have cold water just not hot water. Therefore, it hasn't been critical that it get fixed now.

Since I am down to less than 24 hours before I can leave to go stay with my Grama in the hospital again, I will just recover the hole in my floor and do this when I get back. Same plan - new week.

Okay, here are the photos. First of all, seeing the view from just inside the floor opening, there are 2 sets of pipe running out through the back wall to the water heater. My problem is with the far pipe.

Now, looking just a little closer and from ground level you can kind of see the tricksey way you have to reach this pipe. The leak is at that top joint up there.

Another view from the ground where you can see the offending joint.

And, just for reference, I have given an above the floor view to show where this is located in relationship to the access hole. From the top right corner of the hole there is a trail of pliers, phones and then a maglight standing up over the spot on the floor above the problem.

Any other suggestions? I am not averse at all to the epoxy putty for underwater. Just thought I'd give some reference.
