What is the water supply and the sewer pipe?

Water supply

These are the pipes that provide homes with potable water from the city’s water-supply system. Within buildings, the pipes connect to a valve known as the main stop valve, which can cut off a building’s access to the water service.

Sewer line

The sewer line connects buildings to the city’s sewer system in order to evacuate waste. This pipe leads to a branching called a cleanout, located close to the main stop valve inside the building, which allows the sewer line to be cleaned once it is unscrewed.

Storm drain

The storm drain is a third pipe system required in some cities. This piping collects and directs rain water coming from the French drain, the sump pump and the rooftop drain.

These 2 or 3 pipes are commonly referred to as the water stop.

Homeowner responsibility

As a homeowner, you are responsible for maintaining and repairing, when necessary, the water-supply system piping coming from your home up to the water inlet valve (also called the “service box”). This is the length of piping located between your building and the city’s water main. You are likewise responsible for the sewer line and the storm drain, from the center of your property up to the valve located on your lot.

What are the signs and symptoms of a water stop problem?

  • Frequently clogged toilets
  • Rotten egg smell coming from the basement drain
  • Slow draining from the bath, laundry and sinks, especially simultaneously
  • Waste leaking from the basement or garage floor drains
  • Weakening of the water pressure, most evident in second storey showers
  • Consistent presence of rust in potable water, even in systems not made of steel piping

Common sewer line problems and issues

  • Tree and plant root infiltration blocking a sewer pipe
  • Pipe crushed under too much weight
  • Pipe segment sagging or shifting out of line with other segments
  • Punctured pipes with debris obstructing the flow

When to step in and replace the water stop

Water supply

  • When the supply is punctured
  • When corrosion and calcification start to clog the pipe
  • When lead has been detected in potable water (for lead piping)

Sewer line

  • When the line is damaged and impossible to unclog
  • When installing a new French drain
  • When the sewer line’s normal life expectancy expires

Our Specialties

French drain

To make sure a French drain is working at top efficiency, a careful, high-quality installation is necessary. Water accumulation at the footing of foundations must be routed towards a drain, by gravity or by a pump.

Concrete crack repair

Repair methods vary according to the types of foundation problems they address. The best way to permanently repair a crack is still through an exterior repair, even if this requires some excavation.

Pyrite removal

To ensure a proper decontamination, the concrete slab must be removed to replace the landfill rocks and debris with DB-certified crushed stone, conform to interior foundation standards.

Water supply

As a homeowner, you are responsible for maintaining and repairing, when necessary, the water-supply system piping coming from your home up to the water inlet valve (also called the "service box").

Iron bacteria

The iron bacteria (sometimes called "iron-eating bacteria") is a reddish, muddy deposit that occurs naturally in soil and groundwater.
