Service: Main Sewer Line Cleaning

Prefer to talk? (587) 707-3551

Overview

The main sewer line (or lateral) is the single pipe that carries all wastewater from your home or building to the city sewer. Every toilet, sink, tub and floor drain empties into it — so when it restricts, the whole property is affected.

Main line cleaning clears the full length of that pipe from the cleanout to the city connection, cutting through roots and removing grease, paper and debris. A camera run afterward confirms the result and shows what caused the problem.

Our Process

Your main sewer line carries every drop of wastewater from the property to the city connection. When it restricts, every fixture feels it. We clear the main line from the cleanout to the city side, remove roots, grease and debris, and can verify the result on camera.

01

Locate

We find and open the main cleanout and confirm the line runs where we expect.

02

Clear

A heavy-duty cable machine or jetter opens the line and removes build-up along its length.

03

Verify

Water testing and an optional camera run confirm the line is flowing and show what caused it.

Our basement floor drain backed up on a Sunday. PlusFlow called back quickly, cleared the line and showed us on camera what caused it. Clear explanation, no pressure, and they left everything clean.

We booked a sewer scope before buying an older home in Bowness. The technician walked us through the footage and gave us a written summary. It helped us negotiate with confidence.

Our restaurant kitchen lines kept clogging with grease. They hydro-jetted the lines after hours so we didn't lose a service, and set us up on a regular schedule. No problems since.

Big old poplar in the front yard and slow drains every fall. They cut the roots, ran a camera after, and recommended a maintenance interval. Friendly and on time.

Gurgling toilet and a slow tub. The tech explained the difference between snaking and jetting and recommended the simpler fix. Honest advice — I'll call them again.

Before our basement development we had the line inspected. They found an offset joint we never would have known about. Great communication from booking to the final report.

Water came up through the basement floor drain every time the washer ran. They cleared the main line, ran the camera to the city connection and showed us a root spot to keep an eye on. Straightforward and tidy.

Toilet overflowing on a weekday evening with family coming over. I called, they told me what to shut off and were at the door that evening. Line cleared and the price matched what I was told on the phone.

We needed the sewer line marked before building a garage. They traced it with the camera and locator and painted the route and depth on the lawn. Our contractor knew exactly where not to dig.

Kitchen sink kept clogging no matter how often it was snaked. Jetting cleared years of grease out of the line and it has drained perfectly since. They explained everything without the upsell.

Sewer scope on a 1960s bungalow before we made our offer. The written report was clear, with distances and photos of a belly in the line. Worth every dollar for the peace of mind.

FAQ

Answers to what customers ask us most about this service.

Book This Service

Most main lines are cleared in one visit. Time depends on access, line length and what's causing the blockage.

A working, accessible cleanout makes the job faster. If there isn't one, we may need to access the line through a toilet or other fixture, which can add cost.

The camera confirms the line is clear and shows what caused the blockage — roots, a sag or damage — so you can plan ahead.

Yes, for eligible standard blockages: if we can't clear it, we waive the clearing charge.
