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.

Service · Calgary
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.
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.

No clear, no clearing charge
On eligible standard blockages.
Spot Problems Early
Problems build up gradually. Watch for these warning signs before a small issue becomes a backup.
Several fixtures slow at the same time.
Water rising in the basement drain when the washer runs.
Especially when a tub or washer drains.
Smells near the floor drain or cleanout.
Standing water visible when the cleanout is opened.
Can indicate a leak in the line underground.

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.
