This tutorial walks through understanding plumbing schedules: a comprehensive overview, covering essential tools and techniques for your projects.

Let's begin looking at the plumbing schedules. So I'm going to start up here. You can see there's a water heater schedule.

Here's the symbol or the mark, what it's serving, what type it is, the BTU input, leaving water temperature, heating capacity, electric demand. The basis of design was a Lochinvar AWN400PM. The sump pump schedule.

Here's the mark, what it serves. It's a submersible sump pump. Where is it located? GPM, revolutions per minute, head (ft), HP, and it's a Sta-Rite Core.

The fire pump schedule. Here's the mark, what it serves, what kind it is, GPM, RPM, frame size, basis of design. Jockey pump schedule: similar format.

Here's the mark, what it serves, its type, basis of design. The domestic water booster pump schedule.

Here's the mark, what it serves, what kind, and the basis of design. Circulation pump schedule: follows a similar pattern.

Mark, what it serves, what kind it is. Storage tank schedule: similar information provided.

Gas pressure regulator schedule. Includes the mark and additional physical specifications.

Then the grease trap calculators. This includes a 1,500-gallon grease trap—quite large.

It's quite sizable. Now let's pan up here. Plumbing specialties.

Again, the symbols are here and descriptions. I'll just pan through this. Floor drains, floor sinks.

It doesn't specify the exact model, but it outlines the performance requirements they are seeking. Roof drain, cast iron body—to ensure durability. Includes specifications for the washing machine and the eyewash station.

Then if I go over to here, the plumbing fixture schedule. This is where they specify the exact make and model required for the shower, sink, and water closet. They're breaking it down by unit type.

Similar information here. Public restrooms. Specifications on what they want.

Fitness restroom and employee restroom. This sheet conveys a lot of important information in a consolidated and well-organized format.

So please feel free to look at your copy of the PDF and learn a bit more.
