Sewer Smoke Test

Home / Sewer Smoke Test

Tracking down a sewer smell or a hidden line problem without guessing.

A persistent sewer odor with no obvious source, a suspected illegal connection between storm drains and your sewer line, or a city/inspection requirement before a property sale or renovation — a smoke test finds the answer without tearing anything open first.

 

Texas Plumbing & Drain performs sewer smoke testing for homes and businesses across Aledo, Weatherford, Fort Worth, and the west DFW Metroplex.

WHAT WE ACTUALLY DO HERE

Sewer Smoke Testing

We introduce a safe, non-toxic smoke into your sewer line and watch where it surfaces. Smoke escaping from a spot it shouldn’t — a crack in the line, a loose joint, an unauthorized connection, a dry drain trap somewhere in the house — shows us exactly where the problem is, visually and immediately.

Odor Source Identification

When you’ve got a sewer smell in the house or yard and no clear cause, smoke testing is often the fastest way to find it — rather than opening up walls or digging based on a guess.

Cross-Connection & Illegal Connection Detection

Storm drains, roof drains, or other lines that have been improperly connected into a sanitary sewer system show up clearly during a smoke test, since smoke traveling through the sewer line will surface anywhere those connections exist.

Pre-Sale & Compliance Smoke Testing

For property transactions or situations where documentation of sewer line integrity is needed, we perform the test and can provide you with what you need for the record.

FAQ — STRAIGHT ANSWERS

What actually happens during a sewer smoke test?

We seal off sections of your sewer line and blow a safe, non-toxic smoke through it under light pressure. Anywhere that smoke escapes — a cracked pipe, a loose joint, a disconnected vent, a dried-out drain trap — tells us exactly where an opening exists that shouldn’t be there.

No — it’s a non-toxic smoke specifically designed for this kind of testing. It’s used because it’s visible and travels through the piping system the same way sewer gas would, making leaks and unauthorized connections easy to spot without any real risk.

Common causes include a dried-out drain trap (common in a rarely-used bathroom or floor drain), a cracked vent pipe, or a loose connection somewhere in the system. A smoke test surfaces exactly where the gas is actually escaping, rather than guessing room by room.

It’s when a storm drain, roof drain, or other line has been improperly tied into your sanitary sewer system — sometimes from older construction practices, sometimes from a mistake during work done by someone else. Smoke testing reveals these clearly because smoke traveling through the sewer surfaces at the cross-connected point.

Not always required, but it can be a smart step if there’s any history of sewer odor complaints, or if a buyer’s inspection raises a question about the sewer line’s condition. It gives you documented answers instead of open questions during a sale.

If there’s an issue inside your home’s plumbing (like a dry trap or a disconnected vent), you may see a small amount of smoke at that specific fixture — that’s actually the test working as intended, showing us exactly where the problem is.

Most residential smoke tests are completed in under an hour, depending on the size and complexity of the sewer system being tested.
