Plumbing - Science of Religion?

Plumbing has adopted the scientific mode. However, from a strictly scientific point of view, it has not been able to meet the requirements of true science.

How do I know my plumber won't badly fix my pipes and charge me up the ass for it?  I don't.  It requires faith.  So, plumbing is a religion.  QED

It's neither.  It's a trade skill. 

But I do detect a newfag.  Summer is here.
