There are at least 3 things that a welder can not fix;
A Plumbers Crack, The Crack of Dawn or a Broken Heart...
Theory only works perfect in a vacuum.
One question that I have never got an answer to is "Why is it ALWAYS the plumber's crack?" I have never had a problem with mine, (I keep my shirt tail tucked in), and I am sure AC men and electricians also "bend over" while working.
Licensed residential and commercial plumber
The welder on Flashdance (Jennifer Beals) could fix a broken heart. She could break a lot of hearts too.
Around here we don't call it a plumber's crack, we call it butt cleavage.
