Sprinkler System Backflow Testing, Repair & Replacement

  • Irrigation Backflow Repair or Replacement

    Lewis Landscape is licensed for and does repairs and replacements of backflow devices. A Double-Check Valve Assembly (pictured left) is the most commonly used kind of backflow device in the Northwest. That’s what 99% of residential homeowners have these days.

    Most of the time if a backflow device won’t pass it’s annual inspection, it’s usually time to just replace the entire unit. But there are times when the unit is repairable. An appointment with one of our Service Technicians can determine whether it can be repaired or just needs to be replaced entirely. Often as a backflow device ages (8-10 years old or more) it is better to just replace the entire apparatus, rather than continually throwing parts at it, as they break. Replacing a backflow device requires us pulling another permit from the city or county, a completely new backflow device and fittings and many hours of labor and a new backflow device. This will generally end up costing in the $1900-$2300 price range. Please call us or fill out our contact form if you need any backflow repairs or replacement.

  • Who to Contact for Backflow Testing

    As of July, 2019 we have decided to pull out of the backflow testing business. We no longer provide Backflow Testing service other than for new backflow devices that we have just installed.

    If you’re just in need of annual backflow testing, we recommend contacting Flowcheck, LLC at (503) 444-1148

  • Why is Backflow Testing so important?

    Backflow testing protects your drinking water and that of your neighbors as well. If there ever was a backflow situation (e.g. the fire department opened up a fire hydrant down the street that that suctioned water pressure away from your house) then water that had been sitting in your old sprinkler pipes is now mixing back into the main pipes that everyone is drinking from. Imagine if your sprinkler system had not only stagnant water inside it, but maybe there was a broken pipe or sprinkler head in your system. This break had allowed contaminants such as dog feces or fertilizer or herbicides to get into the lines. Now THAT water is going back and mixing into the drinking water. It sounds unlikely, but it’s happened hundreds of times throughout the United States. This is why backflow testing is required everywhere now.

    Backflow preventers ensure cross-contamination like this doesn’t happen. The main variety of backflow preventer we use here in the Northwest is a Double-Check valve, which means you have two layers of protection. If one fails, the other one will still prevent contamination in a backflow situation. But these devices eventually do begin to fail. This is why they need to be tested annually.

    With annual testing, we can catch a backflow device that is going bad, before it actually breaks and can get it fixed. By detecting a failure early and fixing it, we can protect you, your family, and your neighbors from a potentially hazardous cross-contamination problem.

We’ve had Jim Lewis come by and help us with the yards at two homes over 13 years now. Both involved deconstruction and renovation. We usually have tentative ideas that Jim helps us flesh out and improve. Then the crew arrives and magic occurs. We’ve also had Lewis Landscape Services come do the annual maintenance on our irrigation. That saves us headaches and the cost of replacing dead plants next year. The office staff is kind; the crews are great; and for Jim it’s personal. It’s your home and he wants it to be right for you.

I hired Lewis Landscape after receiving a well presented estimate accompanied by recent project photos. The price was fair and the quality met my expectations. My neighbors all commented on the craftsmanship. The paver patio and walkway are now the focal point of my home. Thanks for a job well done.
