Pipe Placement 101

Ensure your plumbing connections are in the right spots with this guide to kitchen and bath rough-in

Plumber Brad Casebier provides this guide to kitchen and bath rough-in, which works with about 80% of the entry-level to mid-level fixtures he and his crew install. For the bathroom, diagrams show rough-in locations for a tub/shower, a vanity sink, a pedestal sink, and a toilet. For the kitchen, rough-in locations are shown for a sink, and a second drawing shows how to place an ice maker. For each room, Casebier provides a list of "gotchas," or situations you can avoid with a proper rough-in. He also includes guidance and "gotchas" for roughing-in a laundry room. A chart shows specific Uniform Plumbing Code and International Residential Code requirements for securing seven different types of pipe and tubing in both horizontal and vertical spaces. A second chart shows the UPC and IRC requirements for minimum trap size for 14 different fixtures.
