Question:
What is backflow?
Answer: Backflow
is the undesirable reversal of the flow of water or mixture of water and/or
gases and other substances into the water distribution system. Common causes of
backflow are water main breaks, pressure loss in the distribution system, and
high demands on the water system caused by firefighters during a fire. The most
common cause is due to an unattended garden hose left in a sink or bucket.
Question:
Why is backflow protection
necessary?
Answer: To ensure
safe and clean drinking water to all citizens of the City of Show Low
Question:
Who is responsible for
backflow protection?
Answer: Currently,
the City of Show Low has four certified backflow testers/inspectors. They are
governed by federal, state, and local ordinances. However, it is your
responsibility to protect yourself from cross-connections. Here are some simple
tips:
1.
Do not leave your garden hose unattended while watering, especially when
you have chemical feeders attached.
2.
Do not install hoses on your faucets that protrude past the top rim of
your sink. Make sure that there is a minimum inch of space between your hose and
the top of the sink or tub.
3.
Do not put your garden hose in a sewer clean out or roof vent to unplug
your sewer. Call a professional to assist you.

Question:
Where is backflow protection
needed?
Answer: Backflow
protection is needed wherever the possibility of contamination of the public
water supply exists. While the City’s Public Works department has the authority
to regulate commercial buildings only, the need for backflow protection also
exists in residential areas. As a homeowner, it is your responsibility to
protect others in the water system as well as the people living in your home.

Question:
When is backflow protection
required?
Answer: If you own
a business within the City of Show Low, you have been, or will be, visited by a
Public Works employee who will determine each business’ need for backflow
protection. This inspection is usually done when a business changes ownership or
changes industry. However, at times it is necessary to resurvey all commercial
buildings to ensure that everyone is still in compliance. If it is determined
during the inspection that the need for protection exists, the business owner
will be advised as to what type of backflow assembly is needed and who to
contact for proper installation and testing. Once installed, the testing will be
performed annually.
