Sewer Line Repair & Backwater Valves in Lethbridge, AB

Signs of trouble

Several slow drains, gurgling toilets, water rising in the floor drain, or a sewage smell in the basement. When these show up together, the main line is usually the cause rather than a single drain.

Camera first

A camera inspection through the cleanout shows roots, sags, cracks and offset joints, and exactly where they are. That means a repair can be planned without digging up more than necessary.

What a backwater valve does

A backwater valve sits in the main sewer line in the basement. It lets wastewater flow out but closes if water tries to flow back in from the main during a heavy storm or blockage. See our backwater valve guide.

Looking after the valve

A backwater valve needs checking and cleaning so the flap moves freely. Find its access cover, usually in the basement floor, and keep it clear of boxes and flooring.

Repair options

Depending on what the camera finds, the line may be cleaned, repaired at one point, lined from inside or replaced. Ask why the plumber recommends one option over another.

Get it checked

Tell the plumber what's happening and whether you have a backwater valve already. Send a request and a plumber will get in touch.

Roots and old pipe

Older neighbourhoods may have clay or cast iron sewer lines under mature trees. Roots enter at the joints and catch debris, causing repeat backups. A camera inspection confirms it before any digging, and shows whether a cleaning will do or the line needs repair.
