Olsen Sprinkler Irrigation is also committed to the protection of the public potable water supply; therefore, Olsen Sprinkler installs and repairs reduced pressure zone assemblies (RPZ) for backflow prevention. Olsen Sprinkler is a member of the Arkansas Backflow Prevention Association. We also submit to the regulations set forth by the Arkansas Department of Health, State Plumbing Codes, and Central Arkansas Water. The water purveyor holds each owner liable for annual testing of RPZ units. Olsen Sprinkler is certified to test and repair any kind of backflow device. Olsen Sprinkler provides the initial test before the acceptance date at no cost. Olsen Sprinkler suggests the removal of the backflow preventer (RPZ) in the fall (October) in order to prevent damage due to freezing. Olsen Sprinkler offers this service at an additional cost. This warranty does not include winterization or spring start-up.
