Backflow Testing Information

Backflow testing is required to protect  all of us from harmful chemicals and impurities that can enter our  drinking water through backflow or cross-contamination. (For more  information, see: EWEB Backflow Prevention Information.)


Terra Nova is licensed, insured, bonded, and certified by the State of  Oregon's Department of Human Services.  We specialize in backflow  installation, testing, inspection, and repair.    

Because state law requires you to have  your backflow system tested annually, Terra Nova offers  fast, reliable testing at competitive, guaranteed rates. WE MATCH ALL COMPETITOR PRICES.  Simply complete the form below to request your test.   


NOTE: If you are an EWEB customer, we'll notify EWEB that your backflow test has been scheduled with us (which satisfies their requirements for you).  We strive to complete the tests as quickly as possible. During  our busy season (spring/summer months), it can take from a few days to  several weeks to complete tests, depending on your area. We'll notify  both you and EWEB of the results and leave an invoice on the property on  the date of service.       


We will contact all non-EWEB customers  and EWEB customers who have special requirements and/or who have backflow devices inside or not normally accessible to schedule backflow tests. Non-EWEB customers,  please include your backflow device serial number and device location  below.  

For your convenience, we offer an automatic annual retest option (required for discounted rates). Merely click yes on the "Annual Auto Test" box and we will come out annually when your backflow test is due, test it, and provide you and your water board with the results.
