This so reminds me of our old landlord who found a hot tub shell and installed all the plumbing himself. Total disaster. Six of us were in it and the jets were going full bore with two feet of snow on the ground and one of the pipe joints blew a gasket. The tub drained in twenty seconds and we froze our tails off. Moral of the story: pipe joints that are meant to be under pressure should not be installed at right angles. Good luck Billy and crew!
