Backflow Testing: Drake’s 7 Dees +

Backflow testing is also included in this program. For our clients in Oregon this takes place through our certified partners at Oregon Backflow Testing. Washington clients are tested through a certified tester from Drake’s 7 Dees. Services include:

  1. Test backflow to make sure both your drinking water and your water district water supply is safe from contaminated water flowing back into the system. Oregon and Washington require that backflow prevention devices are tested on an annual basis.
  2. *Test results will be sent to your water purveyor so you are up to date on your annual requirement.

Testing begins mid-January through March. Tests do not require that the irrigation system is turned on and can be tested during low temps as it does not affect your sprinkler system.
*If your backflow produces a failed test you will be notified by your tester and given an estimate for the cost of repair. After repair a passing test will be sent to your water purveyor.



Pricing is determined by the number of zones in your system.

A lifelong Oregon resident, Drake has been passionate about plants since childhood, beginning with propagating and growing flowers at his grandfather’s nursery. He opened Drake’s 7 Dees in 1974, while earning degrees in Business and Horticulture from Oregon State University. He later expanded into the design/build side of the industry, allowing him to combine his passion for plants with his love of family by maximizing the quality of family time spent outdoors.

Drake is co-founder of the Oregon Landscape Contractors Association and is a Landscape Industry Certified Manager (LICM)—a designation that less than two percent of landscapers have attained. Additionally, Drake serves on the Board of Directors for the Portland Japanese Gardens, widely regarded as one of the seven best Japanese gardens outside of Japan.

Drake is married to former Oregon Speaker of the House, Lynn Snodgrass. Together, he and Lynn received the Farm Bureau President’s award in 1999 for their service and dedication to agriculture in the state of Oregon. Drake and Lynn have two wonderful daughters, two talented son-in-laws, and seven grandchildren. In his spare time, Drake enjoys camping, water and snow skiing, reading, and of course, gardening.

Born and raised in the Portland Metro Area… Tim has had an appreciation for the outdoors from a young age.  Inspired by our local beauty ranging: the Mt Hood National Forest to salty, sea spray of Cannon Beach, the arid high-desert of Central Oregon to the rugged terrain of Steens Mountain – Tim sought higher education at the University of Idaho in their Landscape Architecture department.  Graduating with honors in 2004, he returned home to establish his professional career.

Now making his home in Sandy, Oregon – Tim and his wife [Nicole] are raising two happy and healthy kiddos and 4 fur-babies.  Between soccer, football, cheerleading, girl scouts and other extra-curricular activities… the Sellin family are heavily involved in their community and church family.  Since college, Tim has spent 13 of his 17 years with Drake’s 7 Dees and has ‘set roots’ in anticipation of long-term growth at the family-focused company.  Having spent his time away from Drake’s in a ‘boots on the ground’ capacity, Tim has fostered a love for the operational/production side of landscape business, as well as the design/sales.

His goal in life as well as business is to put others first.
