How it Works:

At Certified Testing Services of Clark County we eat, sleep, and breathe backflow testing so you don't have to. We know our customers have better things to do than worrying about their backflow testing. That's why we handle the entire process from beginning to end.

Our standard residential tests are $49.00. We offer Ridgefield customers a neighborhood discount of $40.00. For that price, we will test the device, generate the required test report, and send an official copy directly to your water supplier.  You will also receive a report copy for your records with your invoice for the year.

As an added convenience we will add your home to our priority routes for the following year. You will receive a courtesy email about a month before your test is due.

We have completed Clark PUD testing for this year. 

WE ARE CURRENTLY NOT ACCEPTING NEW CLARK PUD CUSTOMERS for this year. For all other testing, please schedule below. 

You will receive a WELCOME EMAIL within 1 Business Day confirming your submission and explaining our process.
