Today on Serving Up Plumbing with David Butler, we are going over the practical exam in the state of Texas, more specifically the infamous DOLL HOUSE that you may face on your Tradesman or Journeyman tests! It may be Halloween time, but TRUST ME it's not as scary as it seems. I'll be giving you an in-depth look at the very plumbing dollhouse that I built in our state of the art training facility here at Milestone Home Services! It's not an exact replica of the ones in Austin or Waco, but it's a great tool for training you how to rough in a house! It IS an exact replica to scale of a home. Let me know what you'd like to see next in the comments below! If you'd like to train on this dollhouse yourself, make sure to email me at training@servingupplumbing.com for more info!
