What a backflow preventer is
A backflow preventer is a mechanical device fitted to the consumer's water connection that blocks reverse flow of water from the site back into the public network - protecting the drinking water of every consumer.
Annual Backflow Preventer Testing
A backflow preventer (BFP) is a safety device that stops contaminated water from flowing back into the drinking-water network. The law requires an annual compliance test by a certified inspector. Kesar Digum handles the testing, installation and supply of backflow preventers, and guides you through the process with the water utility - nationwide.

The last line of defense for drinking water
A backflow preventer is a small device with a critical job - to stop contaminated water inside a consumer's site from flowing back into the public drinking-water network. The law requires many types of consumers to install a backflow preventer and to have it tested annually by a certified inspector. Kesar Digum provides the entire service chain - supply, installation, annual testing and filing the certificate with the utility.

Everything you need to know about backflow prevention and the annual test.
Who must install and test
Industrial plants and businesses that use chemicals, buildings with fire suppression, irrigation or cooling systems, hospitals and dental clinics, auto shops and gas stations, and other businesses with a contamination risk.
The annual test
A backflow preventer is a mechanical device that wears over time, so the law requires an annual compliance test by a certified inspector. The test confirms the valves seal properly, and on completion a certificate is issued and filed with the water utility.
Why not to neglect it
Beyond fines from the water utility, a faulty backflow preventer is a genuine health risk. It is the last line of defense between the consumer's site and the drinking water, and it has to work at exactly the critical moment.
