The water leak was coming from the feed valve on the toilet. Each time we stepped on the valve lever a few drops of water would spritz out. The water valve has an end cap on the bottom that contains a spring. We removed the end cap and reseated it which stopped the leak.
This morning we went to our local RV parts shop and purchased a spare water valve to have on hand. Next time we have a water leak from this valve we will not panic, simply replace it with the spare.
The $45.00 we spent on the spare water valve is worth having peace of mind knowing we don't have to panic.
