Backflow Prevention

What Is a Backflow?

Most homes or businesses have a well-functioning water supply system that actively generates sufficient water pressure, allowing water to actively flow from various sources such as showers, taps, garden hoses, etc. When the pressure is inadequate or nonexistent, a pipe can freeze or burst. Less water in pipes can lead to contamination from ground, storage, or other sources entering the system

Somewhat like a reversal of the flow of the solid, gas or liquid into the water supply. To prevent backflow, businesses must install a backflow preventer.

Devices to Prevent Backflow

The best and easiest way to prevent a Backflow is to provide an air gap, which is an open space between the plumbing system and any device like a faucet or valve, any place where water can pool or collect.

Another solution is to install a Backflow Preventer valve at strategic locations in the system. When there is a risk of contamination from fluids to the water system, a Backflow Preventer should be installed.

Backflow Testing & Maintenance Program

It is essential that backflow protection devices be tested as follows:

  • Backflow Following installation
  • Backflow Yearly
  • Backflow Following any maintenance performed on the system
  • Backflow After any incident or suspected incident

It is the responsibility of the property owner to ensure all backflow prevention devices are tested by an approved certifier each year, after any incident or suspected incident or after any work performed on the system.

After testing, the certifier must attach test tags must to all devices. The tags must have enough space for five future test result recordings.

What should be recorded on the tag:

  • Backflow Test date
  • Backflow Company name
  • Backflow Certified tester name and registered number

All tags must have a longevity of no less than five years with no deterioration.

Backflow Prevention – Supply & Installation

Backflow protection installation methods can be performed in different ways, which include:

  1. Zone protection: device isolates a building or area within the property.
  2. Individual protection: installation of the device at the place where contamination may occur within the property.
  3. Containment protection: installation at the property boundary, placed downstream of the meter assembly serving the property. This includes all boundary fire services.

Individual and zone protection devices will still require installation alongside a backflow containment prevention device. All water that is downstream of a containment device is not drinking water if backflow hazards remain within the property.

In such a case, zone and/or individual devices are necessary to prevent backflow risks and safeguard downstream water from contamination.

Installation Conditions:

  • Backflow prevention devices require installation, commissioning, and testing by a licenced plumber.
  • If you have multiple water services or your property has moved, you must install backflow preventer at each connection point.
  • Each device must be sufficiently supported. Minimum distance from meter outlet: 300mm or 5 pipe diameters, whichever is greater.
  • Prohibit connecting the meter outlet and the containment device.
  • To ensure proper testing and maintenance, it is necessary to install or bury a backflow prevention device while ensuring accessibility.
