Signs of Sewer Line Trouble

The sewer lateral runs under your lawn, out of sight until it fails. It usually gives warnings first, if you know what they sound and smell like.

First ten minutes

  • Stop using the fixture that is acting up
  • Note which other drains or taps do the same
  • Find the shut-off nearest the problem

Leave it to us when

Sewage is on the floor, water is coming through a ceiling, or it is the second time this month.

What the sewer lateral does

Every drain in the house eventually joins one pipe that leaves through the foundation and heads for the public sewer beneath the road. In older homes it may be clay tile or cast iron; in newer ones it is plastic. Trouble in this pipe affects the whole house, not one fixture.

Warning signs

  • More than one fixture draining slowly at the same time.
  • Gurgling from a toilet when a sink or tub drains.
  • The floor drain filling when the washer pumps out.
  • A sewer smell in the basement or yard.
  • Unusually lush or soggy patches of lawn along the line.
  • Cleanouts or floor drains that weep after heavy use.

Key test: one slow sink is a sink problem. Every drain slow at once is a sewer problem.

What usually causes it

  1. Roots entering joints in clay and older pipe.
  2. Grease and wipes building a blockage in plastic lines.
  3. Sags or bellies where the ground settled and water pools.
  4. Cracks, offsets and collapses in aging pipe.

What to do

Stop using water as much as you can, especially toilets and the washing machine, until the line is checked. A cable through the cleanout often restores flow. If roots, broken pieces or a hard stop show up, a camera inspection is the next step, so the repair matches the problem. Our drain cleaning service is often the first visit.

Prevention

  • Wipes, even the ones labelled flushable, go in the bin.
  • Grease cools in a can, not in the drain.
  • Know where your cleanout is and keep it accessible.
  • If you have big trees near an older lateral, consider a camera check every few years.

Our pamphlet on what not to flush lists the worst offenders. Where the line has failed, see sewer line repair.

Questions we get asked

Can a sewer line be partly blocked for a long time?

Yes. Many partial blockages grow slowly for months before a full backup.

Will the Town fix my sewer line?

Generally the municipality handles the public portion. The private part is usually the owner’s responsibility.

Is a smell always a sewer line problem?

Not always. Dry traps and vent issues also cause odours. A plumber can tell which.
