Finding the Break Before Anyone Picks Up a Shovel
A smell drifts across the yard on warm days. Or the drains gurgle every time it rains hard. Nothing looks wrong from the surface.
A smoke test answers that question in an afternoon. A blower pushes smoke through the pipe, and the crew watches the ground, the house and the roof to see where it comes back out.
Wherever smoke rises, the pipe is open. That same opening lets soil, roots and rain water in, and it is the spot a sewer line repair is aimed at.
We run this test on homes and small commercial properties around Evesham and Marlton, usually after a backup nobody can explain.
Here is what the test is, what it turns up, and what your morning looks like while it runs.
What a Sewer Smoke Test Actually Is
The idea is simple. Fill the pipe with something you can see, then look for where it escapes.
Air, Not Water
The blower sits at a cleanout or an open manhole and pushes air through the line. Nothing is filled with water, so there is no flooding risk inside the house.
The Smoke Is Made for Pipe Work
Crews use smoke made for testing pipes, not smoke from a fire. It drifts, it is easy to see against grass and pavement, and it clears on its own once the blower stops.
Smoke Takes the Easiest Way Out
Under light pressure, smoke leaves through the first opening it reaches. A crack, a pulled joint, an open cap or a roof vent will all show. Smoke from a roof vent is normal and expected.
One Stretch of Pipe at a Time
The crew tests a section, marks what shows, then moves the blower down the line. Working in short runs keeps every finding tied to a known stretch of pipe.
Everything Gets Photographed
Each place smoke surfaces gets a photo and a mark on the line’s route. That record is what the repair plan and the price are built from.
What the Smoke Shows on an Evesham Property
The pattern of where smoke comes up tells you what kind of problem you have, and whose pipe it sits on.
A Break Out in the Yard
Smoke rising through grass, a flower bed or a seam in the driveway means the pipe under it is broken open. Sandy soil washes into gaps like that and the line fills from outside.
An Open Joint at the House
Older clay and cast iron pull apart where sections meet. Smoke at the foundation or along the first few feet of the run points straight at those joints.
A Cracked or Missing Cleanout Cap
Authority rules put a cleanout just behind the curb line, with another every fifty feet along the lateral. A broken cap shows up fast on a smoke test. If you are not sure which part of that run belongs to you, our guide to which part of the lateral belongs to you follows the pipe from the house to the street.
Rain Water Piped Into the Sewer
Evesham Municipal Utilities Authority rules do not allow collected rain water into the sewer from sump pumps, cellar drains, downspouts, roof leaders or gutters. A smoke test finds those hookups in minutes, because the smoke pours out of the grate or the spout.
Smoke Inside the House
That means a drain trap has dried out, or a fitting behind a wall is open. Sewer gas uses the same opening, so it is worth finding even when the buried pipe turns out to be sound.

What Happens at Your House on Test Day
The test is quiet work. Most of it happens outside, and the house keeps running while it goes on.
Run Water Into the Drains You Never Use
Floor drains, spare showers and rarely flushed toilets dry out. A jug of water down each one refills the trap and keeps smoke where it belongs.
You Do Not Have to Be Home
An outside test runs without you. We only need someone there when the fittings inside the house are part of what we are checking.
If Smoke Comes Inside, Open a Window
Open a window, step outside and tell the crew which room it came from. It clears quickly, and that room is now a finding we can work from.
Tell Us About Breathing Trouble or Pets
Say so before we start. We plan the run around the rooms those people and pets use, and we keep you posted while the blower is on.
Nothing Gets Dug That Day
A smoke test is a diagnosis, not a repair. You get the findings, the photos and a price, then you decide whether to open the ground.
When a Smoke Test Is the Right Call in Evesham
Smoke is the right tool for some problems and the wrong one for others. These are the times it earns its keep.
Backups That Return After Heavy Rain
When a line only gives trouble in wet weather, water is getting in from outside. Smoke shows you where, which a flow of water never will.
A Smell With No Clear Source
Sewer odor in a yard, a crawl space or one room usually means an opening nobody can see. Smoke follows the same path the odor takes.
Use It Alongside the Camera, Not Instead of It
A camera shows shape: the sags, the roots, the broken wall of the pipe. Smoke shows openings to the air. Run both and you know the condition of the line and every place it leaks.
Call the Authority First
If a drain is backing up right now, call the Evesham Municipal Utilities Authority at 856-983-1878. The line is answered around the clock, the service call is free, and they clear the main at no charge. If the problem keeps coming back, they will put a camera down the lateral at no cost to you. If the main is running clear, the trouble sits on your side of the line, and that is when The Sewer Kings comes out to test it.
Then the Paperwork Side of a Dig
Once a test shows a break on your side, the repair has a permit step before the ground opens. Our guide to the permits Evesham requires before the ground opens covers what has to be filed and who files it.

FAQs
Frequently Asked Questions About Sewer Smoke Testing in Evesham
Crews use smoke made for pipe testing, not smoke from a fire. It is meant to be seen, so it looks heavier than it is, and it clears on its own. Tell us ahead of time if anyone in the house has breathing trouble and we will plan the test around the rooms they use.
Something inside is open to the sewer. Most often a floor drain or spare shower has dried out, so the trap no longer holds water. Pour water down every drain you rarely use. If smoke still shows, a fitting or a vent pipe is damaged and needs a plumber.
No. Smoke finds openings, not blockages. A clog, a sag or a collapsed section shows on a camera run instead. On an Evesham property we often do both, then show you the footage and the smoke photos side by side before pricing any repair.
