Last week we introduced our new series on completing plumbing projects yourself, or calling the professional. Over the next couple of weeks, we'll discuss a few scenarios in which you should call a professional.
If you're working on a larger project- remodels or additions, it's best to call the expert. Anything that involves new drain lines or vent lines are best left to a licensed plumber. Water line sizing, gas line sizing and installation should be done by a licensed plumber.
There are laws that deal specifically with proper installation of water piping you need to be in compliance with. Calling the expert assures you these laws are followed, creating less of a hassle for you!
