Backflow Testing Regulations
Backflow Testing Regulations
According to state
law, all backflow assemblies must be tested annually. Many homes in Central
Oregon need underground sprinkler systems because of the high desert.
Regulating water throughout a desert landscape helps prevent leaks and other
damage. According to the Bend
Bulletin, “Homes built since 2003 are required to have a backflow assembly
near the water meter, to prevent tainted water from flowing backward into the
city's water system, but maintenance of those devices is the responsibility of
the city or water district supplying the home.”
Backflow is a reversal of non-potable water through a cross
connection into potable water system. In other words, a reversal of bad water
into fresh water. A good example of backflow contamination would be backflow
into your sink or toilet. Most homes use gravity to move sewage from to the
home to the municipal system. If an older sewage line systems uses galvanized
steel instead of treated PVC, it can cause sewage to back right into your home.
Because a backflow can cause serious damage to the home and
the health of a person, the State of Oregon mandates that all homes be tested
once a year to prevent this from happening. The cost involved in backflow
hazards can be extreme. Wastewater can flood a home within minutes and leave
the home uninhabitable. The most common backflow is when a public sewer system
becomes surcharged by heavy rain or a large snow melt, which happens quite
often in Central Oregon.
To help make up for the costs, FEMA
has a program that may help, “Through the Hazard Mitigation Grant Program, the
Federal Emergency Management Agency (FEMA) offers grants to cities and towns for
up to 75 percent of the total cost to install backflow valve systems in
residences and businesses. This is an important consideration, as cities or
townships are generally not responsible for sewer-related damages since most
stoppages are beyond the city’s control, and thereby the costs fall to the
property owner.”
Since most backflow problems are from municipal systems,
it’s rare that the homeowner may be responsible for the damages and that is why
there are city, county, state and federal help for the cleanup and that is the
reason it is mandatory to get your home tested once a year.
