Tualatin Irrigation Backflow Testing Q&A

Irrigation system backflow prevention devices are used to protect the water supply from contamination or pollution such as fertilizers and pesticides, and are required by law to be tested annually.
What is backflow, and how does it occur?
Backflow is where water flows in the reverse direction from its intended path of travel. Normally water is supposed to go from the main and into the service line for a property. In situations where the water pressure becomes reversed, water flow can go the other way.
How does backflow pose a risk to public health?
In the case of water backflowing from an irrigation system, it may be contaminated with chemicals such as fertilizers, pesticides, or herbicides. Without a proper backflow prevention device, these chemicals can enter into the household drinking water supply or even the main water supply.
How does a backflow preventer work?

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.

How often is irrigation backflow testing required?
Testing of an irrigation backflow device is legally required once a year. The best time to perform the test is before the irrigation system is turned on in the spring to ensure that your sprinkler system will pose no danger to you or anyone else during the time it is in-use. Backflow devices are subject to wear-and-tear, and can be damaged by freezing temperatures. When our Tualatin sprinkler system maintenance team is out to turn on your system for the year, we will recommend testing your backflow valve to ensure everything is in working order.
How much does it cost to install a backflow preventer?
Costs will vary on the kind of valve you need for your system. Contact our team for an estimate.
Will a backflow preventer affect my water pressure?
Installing a backflow preventer may affect your water pressure particularly if not properly installed. For expert backflow prevention valve installation, contact Drake’s 7 Dees.

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.
