DISCLAIMER: I am NOT responsible for any damage done to a property of which the plumbing wasn't done by a professional, I do not recommend doing your own plumbing if you are unsure about what you are doing, always hire a LICENSED contractor when doing any type of plumbing so you can be covered by insurances if something does happen, these videos are for entertainment purposes only!
