Irrigation and Backflow


irrigationShonnard’s Landscape Division also includes a full service irrigation team. A properly functioning irrigation system is very important to a beautiful healthy landscape. Our irrigation team offers routine maintenance, on call emergency repairs, and design and installation services. We specialize in both drip and below ground systems. As an added service, we keep a full line of drip irrigation parts in stock at the Garden Center in Corvallis.

A backflow prevention device is the unit that prevents the dirty used water from flowing back into the good clean water we use to drink. Backflow prevention devices are required to be tested once a year. Our professional irrigation staff includes certified testers.

Customers can request device testing on a call in basis, request to have us just automatically test each year and send a bill, or sign up for our Sprinkler/Backflow Program.


Shonnard’s Annual Sprinkler/Backflow Program is a combination service plan. It includes:

  • First hour of service for the spring irrigation system turn-on/check
  • One back flow test
  • And the first hour of service for the irrigation turn off/fall winterization.

Labor over the first hour and materials are billed additionally. Does not inculde repair work. The program runs from January to December.
