Drip in bathroom sink.
Terrible pic, sorry, not much room for a old guy to move around! You can see the drop just to the right of the tee. We are lucky that the cleaners stored under the sink were in a large plastic container and noticed the water at the bottom. Another good reason, every once in a while to : (A) check under the kitchen & bath sinks. (B) Shut down the shore water and go to the pump and listen for it to cycle, especially if you've been on some nasty roads! We dodged a bullet on this one, though fixing the leak is not in my job description. Thankfully, we have a tech that lives n the Park, who has tools and fittings. +, he is about 30 lbs lighter and much younger than I !
