Cleanout

A cleanout is an access point in a drain line that lets a plumber clear clogs.

Why it matters

A reachable cleanout can turn a messy backup into a quick fix.

Where people get this wrong

Do not bury cleanouts behind cabinets or drywall. A cleanout is different from a floor drain.

Real-world example

Years after move-in, a drain backs up. The plumber finds the cleanout hidden behind a built-in. That is when a simple fix turns into demo work.

Where this hits your build

This comes up during rough-in and final fixture installation. Accessibility for future repairs matters as much as the initial install.

Most people do not just struggle with terms. They struggle with the decisions tied to them.
