Backflow prevention is the method used to stop cross-connection either directly or indirectly of a potable water supply (water that is suitable for human consumption, food preparation, utensil washing and oral hygiene) with non-potable or contaminated water or any substance.
Why is backflow prevention so important?
Only drinking water shall be supplied to plumbing fixtures or outlets for human consumption, bathing, food preparation or utensil washing. All water supply systems shall be designed, installed, and maintained so as to prevent contaminants from being introduced into the water supply system to protect human health.
Where do we start?
The backflow protection required shall be determined by identifying the individual hazards within each commercial/industrial premises/boundary. Each premises can be identified by their water usage. High water users may pose a greater threat to the community. Currently there is a greater need to protect our own water supply and the health of people working within the specific premises that are at risk.
What are some typical cross connections found in a residential home?
The most common types of cross connections found in the home include:
- Garden hose attached to an outside tap or hose bibb with the end of the hose connected to a pesticide sprayer or left submerged in a ornamental pool
- Underground lawn watering (irrigation) system
- Laundry sink with submerged hose
- Handheld shower head immersed in water
- Hot water heating system
- Home fire protection system
- In-home water treatment (softener) system
- High-pressure washer
What will a backflow preventer do for me?
A properly installed and working backflow preventer will protect your family or business from contaminants flowing backwards into your household drinking water piping.
Why do backflow preventers have to be tested regularly?
Backflow preventers have internal seals, springs, and moving parts that are subject to fouling, wear, or fatigue. Therefore, backflow preventers have to be tested regularly with calibrated equipment to ensure that they are functioning properly. Typically, backflow preventers are tested once each year.
Who is responsible for having a backflow preventer tested?
Generally, the owner of the residence, building or property manager is responsible for having the preventer tested. If the backflow preventer belongs to the tenant then the tenant is responsible for having the preventer tested.
Who can test backflow preventers?
Only an individual who is a Certified Backflow Prevention Assembly Tester and has been certified by the State of Florida is permitted to test backflow preventers.
