Backflow Prevention in Calgary, AB

The plumbing system for any building is made of two halves: the freshwater and the wastewater half. Your home is no different. It’s harmful for wastewater and freshwater to come into contact with each other, since it can lead to the contamination of the freshwater supply with bacteria and other harmful pollutants. Thankfully, there are few places in your home’s plumbing where water from the sewage side will accidentally move into the freshwater side.

Some homes may require a backflow preventer to stop wastewater from entering the water system. If your home has a backflow prevention device in place, or needs one installed, call on Ace Plumbing and Heating in Calgary, AB. We are licensed to do backflow testing to ensure your home’s plumbing system isn’t creating potential health hazards.

The Job of the Backflow Preventer

A backflow preventer is a device designed to stop the movement of wastewater the wrong direction through the plumbing system so it enters the freshwater side. This can happen either due to an increase in pressure on the sewage side or (more likely) a drop in pressure on the freshwater side. This can happen for several reasons:

  • Firefighters put a large demand on the local water supply
  • A break in the water main
  • A large power outage
  • A new plumbing appliance placing large demand on the water supply
  • Any plumbing work requiring draining down the whole house.

A backflow prevention device contains a check valve that automatically shuts in case water attempts to move the wrong direction through a cross-connection between the freshwater and wastewater sides. This avoids harmful contamination of the drinking water supply.

Does Your House Need a Preventer or Backflow Testing?

Most commercial buildings require backflow preventers because they contain major cross-connections linking freshwater and wastewater piping. For homes, this is less common. The "backflow preventers" in a home are simply the air gaps between drains and fixtures. Sewage may flow the wrong direction from a drain, or the faucets might start to suction up water—but the sewage won’t make the jump up from the drain to enter the fixture because the fixture is higher up.

However, there are places in a house where cross-connections can occur: dishwashers and laundry machines, as well as hand-held showerheads that can end up lower than the drains. Cross-connections are also located outside the house with hose bibs and lawn irrigation. If a home contains cross-connection hazards, it will need a backflow prevention device—and this device will require regular backflow testing.
