Plumbers show crack because they bend over all the time. I think the plumbers on my job smoke crack all the time instead. I guess it was to hard to bend over and attach the supply hose to the fixture which has the same threading. Instead just punch a hole in the wall and make your own fixture. Even better they have the water pressure for an 18 story office building going to a few taps so you turn it on and it blasts water so hard the flexible pipe movers up and sprays all over!
