Mr. Backflow
Company Overview
Did your water district send you a letter informing you that your Annual Backflow Test is due shortly? Mr. Backflow is here to inform you about backflow testing and its role in protecting you from health risks and financial setbacks. We believe in progress, not regression. Let us assist you this month with our special discounts on testing services.
Mr. Backflow is a family-owned and operated business with Christian values. We specialize in the testing, repair, installation, and upgrading of backflow assemblies across North San Diego County.
Our goal is to deliver outstanding backflow services along with trustworthy customer support. All commercial and residential backflow assemblies require annual testing to adhere to regulations and meet city standards. Customers rely on us annually to handle their backflow testing. We ensure that copies of compliance reports are sent to your local water authority after each backflow prevention test. We keep track of annual testing dates, so our customers can rest easy knowing they won’t miss any deadlines. Building enduring relationships with our clients is something we take pride in.
