You mean like angle stops, solder, and copper tubing?
I couldn't care less if they were giving the parts away free on every street corner.
Proper plumbing maintenance requires knowledge of how to protect potable water, how to properly handle sanitary drainage, and why it must be done. Licensing laws in our trade are already much too weak and in most states there is embarrassingly little enforcement.
No one has any business touching a plumbing system without knowing the implications of their actions. The only method we have for that (as flawed as it may be) is licensing. The more restrictive, the better.
Unlicensed drain cleaners are some of the worst violators of licensing laws. They are forever on the slippery slope of "while you are here...". They also have money making repair opportunities laid at there feet because they often discover a problem with the plumbing system in the course of maintaining drains.
So when a drain cleaning company cables a line only to find a broken riser, do you think they are really going to ignore the profit opportunity?
Will they not offer to replace the leaking water heater that initially looked like a backed up condensate drain?
Will they not offer to repair the broken closet flange?.
Will they not try to charge for replacing the lead tub drain that now has a hole from the cable?
Will they not charge to replace broken connection from a lav p-trap to the santee in the wall?
While there are some states that allow drain maintenance without specific training, testing, or credentials, that does not make it right. And of course there are countless people maintaining drains without credentials that are VERY PROFESSIONAL at what they do. But would it not be better to have verifiable expertise for those professionals rather than it be luck-o-the-draw?
