Sewer lines fail slowly. The problem usually starts small — a little buildup, a tiny crack, a thin root tendril — and grows over months until one day it becomes an emergency. If you know the warning signs, you can catch it early when repairs are far less expensive. Here are the seven signals Edmonton homeowners should never ignore.
Multiple Slow Drains
If more than one drain is slow — especially on different floors — the blockage is likely in your main line, not a single fixture.
Gurgling Sounds
Gurgling from toilets or drains when water runs elsewhere means air is being pulled through a partial blockage.
Sewage Odours
Persistent sewer smells indoors or around your yard suggest gas escaping from a damaged or blocked line.
Water Backup in the Basement
Water pooling around floor drains or in the lowest part of your home is a classic sign of a main line blockage.
Soggy or Sunken Patches in the Yard
Unusually green or soggy spots above your sewer line can indicate a leak or crack underground.
Frequent Clogs in the Same Spot
If the same drain keeps clogging no matter what you do, there's a deeper issue that snaking alone won't solve.
Cracks in Foundation or Walls
Small cracks appearing in your foundation can be a sign of water escaping from a failing sewer line.
What To Do Next
If you notice any of these signs, don't wait. A professional video camera inspection can show exactly what's happening inside your line — whether it's root intrusion, grease buildup, a bellied pipe, or a crack. From there, we can recommend the right solution, from hydro jetting to pipe repair.
Catching these issues early is the difference between a simple cleaning and a major excavation.
