Backflow Testing

We do backflow testing in your neighborhood!

Cross-Connection Control, Backflow Prevention, and Water Quality

Your neighbors have entrusted us to do the backflow testing on their sprinkler systems. You may have received a notice from the city that your device is due for testing as well.

Backflow devices protect the public water supply from contamination. A backflow device on your sprinkler system prevents the reverse flow of contaminated water from the sprinklers back into the city water supply. Lawns and landscapes contain fertilizers, chemicals, bacteria, dirt, fungus, and other hazards.

Cross-connections can occur between the PWS distribution system and private irrigation systems, fire sprinkler systems, and other piping systems that receive PWS drinking water. These hazards can contaminate your drinking water if not properly protected and cause serious health risks to the public.

The EPA requires backflow devices. Your municipality requires annual testing to ensure devices continue to work properly.

Sanitary surveys, conducted at least once every three years for community water systems and once every five years for non-community PWSs, offer opportunities to identify potential cross-connections that put public health at risk.

Indicators of a Cross-Connection and Backflow Incident

  • Customer complaints of odor, discoloration of water, or direct physical harm are the primary indicators of a backflow incident.
  • Decreases in water pressure can indicate the occurrence of a backflow incident, as well as suggest where the incident may have occurred.
  • A short-term reduction in disinfectant residual could indicate a potential backflow incident.
  • During periods of reversed flow, water meters might run in reverse.
