Regular testing of backflow prevention devices is essential for ensuring that your plumbing system is working properly. Backflow prevention devices allow water to enter the property’s supply system through the water meter, which also prevents water from flowing back in the opposite direction.
These devices are subject to wear and tear over time, and need to be serviced or replaced when necessary to ensure your water supply remains safe for consumption. Backflow prevention testing is recommended at least once a year to prevent contamination of your potable water supply.
What does the term backflow mean?
The term blackflow refers to potentially contaminated, non-potable water flowing in the opposite direction and entering your drinkable water supply. If this happens and you consume contaminated water, you could experience a number of health issues ranging from gastrointestinal issues to a decreased immune system and more.
What is the reason for a backflow?
A reduced water pressure in the pipes allows contaminated water to be drawn back into your water supply system. This can happen under the following circumstances:
- A burst water pipe in your surrounding area
- Usage of water at a higher pressure than normal
- Fire fighters using water from the main water supply
Increased demand from the main water system will reduce the water supply and pressure to your property, which could cause a backflow.
Where does backflow happen?
Backflow happens in the water pipes, often when there’s a burst or frozen pipe, when the pipes get backed up, or there’s a sudden drop in the water pressure.
What are the main causes of backflow?
The root cause of backflow is a reduced water supply pressure, which creates a negative pressure that allows contaminated water to be siphoned into the drinking water supply. Reduced water pressure can happen due to a number of factors, such as the following:
- Back Siphonage
A typical example of the ‘Venturi effect’, back siphonage is equivalent to sucking liquid through a straw. Back siphonage happens as a result of reduced pressure in the pipes due to an interruption in the water supply. Examples of these interruptions include a main break or repair or increased water velocity (speed) due to a heavy draw on water such as fire fighting. - Backpressure
Backpressure backflow is a consequence of the system operating under higher pressure than the pressure within the water distribution main. This increased pressure forces contaminants from the water system into the potable water supply.
Common causes of backpressure backflow include improperly equipped hot water heaters, pumps, elevated piping, or other equipment attached to the potable water system that’s operating under pressure.
