no, just caught me at a snarky moment. I was looking excitedly for a mechanical engineer story when I saw your post title, and found a plumber story instead. (My confidence with plumbing did go up after the mechanical engineering job I did for a while that involved building robots that were powered by hydraulics and ordering the right fittings and hoses... if I hook up the dishwasher wrong it just spills water, rather than hydraulic oil!)

but I'm glad they came to your rescue, in any case!
