I got a letter in the mail saying I have to hire someone to come test my back flow prevention devices installed in my water supply plumbing.....does anyone know how much this costs?

Contact Jerry Peebles 360-787-8529. He does ours. $35 and he files the paperwork with the city for you. He'll even come out if you're not home, test it, and either leave an invoice for you, or you can leave the money under your doormat or somewhere.
