Help,
I have discovered several small puddles of water inside my TT.
One was found under the bathroom sink and one behind the toilet (fixed by both tightening the water line connection).

Yesterday I found another near the water pump (this one was pretty large). Since there are a lot of water line connections in this area, I have not yet isolated the leak and left the water shut off when I went to work today.

Does anyone know of a dye that is safe to use in the water system to help locate a leak? We have a dye that we use at work to isolate leaks in diesel fuel lines, but obviously I don't want to use this stuff on my fresh water system.

And yes, I know that this is a fresh water leak as the water is perfectly clean.
