By clicking Yes you agree to use Napa Valley Backflow each year for your backflow testing. There is no binding contract and you can switch service
providers at any time. When we put you on our yearly cycle, we schedule your test according to the required test date provided by the city. We send a postcard
in the mail with a test date, usually timed to the arrival of the city letter that comes in the mail. By having us schedule your test you don't have to worry
about finding a tester each year and we file all of the paperwork with the city.
