Septic System Inspection & Test Indoors: What to Watch For Inside the Building

Septic dye leak at drain line

What should you look for inside the building before, during, and after a septic system inspection and test?

Check for in-building drain leaks: At the start of your septic dye test, inspect the fixture drain and (if a basement or crawl space expose the drain piping) check for other leaks in the building.

Always be sure that there are no leaky traps or drains before you leave water running in a building.

Watch for sewer line backup in the building - indicating system blockage.

Check all fixture drains before leaving water on.

Check floors below running fixtures for signs of current or previous leaks.

Don't risk flooding or damaging the building by leaking or overflowing fixtures. If leaks prevent testing, document this information.

Check fixtures periodically during the test period, to assure no leaks or overflows.

Find the main building drain sewer line or waste line

Sewer line leaving building on to septic tankIf you didn't do this before, locate the sewer pipe exit point in the building.

Confirm that the tub/sink drain for the fixture being used to load the system is in fact draining into the sewer line.

It is important to take this step early in the test cycle, and to check all building areas to be sure that you are not inadvertently spilling water (and dye) anywhere inside.
