Where does the problem show up?
Select a symptom to trace its drainage path.
We’ll highlight the fixture, the connected branch, and the main line when the symptom may involve a shared part of the system.
The symptom and the source are not always in the same place.
A single fixture can have a localized restriction. When multiple fixtures react together, a shared branch or main line becomes more important to evaluate.
Fixture
Start with where you notice the symptom.
Branch drain
Nearby fixtures can join before reaching the main line.
Main line
Problems farther downstream can affect several fixtures at once.
Now turn the symptom into useful information.
Follow the Flow teaches the layout. The Drain Diagnostic asks adaptive questions about what is actually happening at your property.
