Our Drake’s 7 Dees certified irrigation technicians are the best in the business with over 40 combined years of experience. They are licensed and certified in both Oregon and Washington for backflow assembly installation and testing (LCB #5259). We take care of it all – even sending your test results to the water purveyor on your behalf.
Backflow testing for irrigation systems is an annual requirement – schedule your Cornelius irrigation backflow testing today.
Backflow preventors are essential to maintaining the health of your drinking water. For this reason, the installation of a backflow device is specifically regulated. To ensure that your backflow preventor is properly installed, let the Cornelius sprinkler system maintenance team at Drake’s 7 Dees handle the details.
Regular backflow testing ensures that your backflow preventor is operating as it should. Trust the trained and experienced pros at Drake’s 7 Dees to take care of your water quality. We manage everything so you don’t worry about it – down to filing the paperwork for you. Cornelius irrigation backflow testing is typically performed in the spring before your sprinkler system is turned on – make your appointment today.
If you are interested in adding multiple aspects to your landscape including an irrigation system, please see our Design and Build contact form. Our Landscape Design and Build department is currently offering irrigation installations as an element within a custom landscape design. The Irrigation Repair Department does not offer this service.
A backflow preventer acts as a one-way-valve which allows water to flow into your irrigation system, and prevents it from flowing back the other way.
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.
