Anytime you use water for industrial
purposes, you are in need of a backflow prevention valve.
Imagine, for example, that you own a car wash. One day, the water pressure supplied
to your property may drop unexpectedly. When this happens, the water flow to the
soap water tank could reverse. When water pressure is restored, the local city
water can be contaminated by the soapy water from the tank. Every building on
your street could then have soapy water flowing out of their taps. Obviously,
in industry, things could get even more extreme. Facilities that process acids,
toxic chemicals, or sewage need to prevent a reversal of water flow at any cost.
This is where backflow valve comes in. During a time of water pressure fluctuation,
the valve will prevent your facility's materials from flowing into the water supply.
If you need a backflow device (valve), you will usually be notified by the city
or county's water or health department. Most commercial businesses will need backflow
devices installed, particularly when they are located in hilly areas or areas
with volatile water pressure conditions.
The building owner can install the device himself or herself as long as all laws
and regulations are followed. Or, the owner can hire a licensed backflow certifier.
The cost of a backflow device will vary according to size, which varies from 3/4
inch (homes) to 10 inches (for large facilities) and difficulty of installation.
In most cases, backflow devices must be tested and certified annually or more
often, as determined by your city, county, or state's regulation. Most valves
can be tested in an hour or less.
After completion of test, the owner of the backflow device is given a certified
test report. Most devices pass inspection. But if the device fails, there is a
legally enforced time limit in which the valve must be repaired or replaced.
We are licensed and certified in all areas of backflow installation, certification,
and maintenance. We hope that you will contact us. However, whether we get your
business or not we strongly recommend that whoever does handle your backflow installation
is certified and licensed. This is essential for the continued protection of our
most important resource - water !
