That\u2019s why backflow prevention isn\u2019t just a common-sense safety measure but a code requirement.<\/p>\n\n\n\n<p>If you\u2019re struggling with backflow issues or need to ensure your plumbing system is code-compliant, contact F.H. Furr Plumbing, Heating, Air Conditioning &amp; Electrical. For over 40 years, we\u2019ve provided exceptional plumbing services in DC and Northern Virginia.

It can result from valve failures intended to prevent such things or unexpected pressure pushing water through weak seals on your pipes.<\/p>\n\n\n\n<p>Backflow preventers are required to keep water from moving backward and carrying contaminants from your plumbing into clean water supplies. However, other forms of backflow can exist, which risk your health and property, even if municipal water supplies are safe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Our Backflow Prevention Testing Process<\/h2>\n\n\n\n<p>Preventing backflow starts with a complete understanding of the situation in your plumbing and any potential sources of backflow. During your appointment, our team will follow this backflow testing process:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Identify the location of your backflow prevention assembly<\/li>\n\n\n\n<li>Shut off your water supply<\/li>\n\n\n\n<li>Connect test hoses<\/li>\n\n\n\n<li>Open all water taps and observe the results. If water runs backward, your plumbing system requires service.<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<p>For situations involving potentially unusual cases of backflow or other forms of contamination, we can conduct further tests to determine whether water is entering your plumbing from inappropriate sources or moving the wrong way through your plumbing despite preventative equipment.<\/p>\n\n\n\n<p>We\u2019ll ensure your property is not at risk of backflow issues or code compliance problems. Call F.H. Furr today to schedule a backflow prevention test in DC or Northern Virginia.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Benefits of Backflow Prevention<\/h2>\n\n\n\n<p>Backflow prevention is a worthwhile investment. Maybe you\u2019re considering taking your chances or dealing with the consequences of backflow only when it becomes serious. However, there are many reasons to get ahead of backflow problems with proper prevention, including:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Stay compliant with regulations<\/li>\n\n\n\n<li>Prevent potentially dangerous water contamination<\/li>\n\n\n\n<li>Protect your plumbing from accelerated wear and tear and corrosion from environmental contaminants<\/li>\n\n\n\n<li>Reduce the risk of catastrophic backflow causing damage to your plumbing or your property<\/li>\n\n\n\n<li>Prevent backflow from carrying contamination into municipal water supplies or your well<\/li>\n<\/ul>\n\n\n\n<p><\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Choose F.H.

If you\u2019re unsure, F.H. Furr can inspect your plumbing and confirm whether one is installed and functioning properly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do I need a permit for backflow prevention installation?<\/h3>\n\n\n\n<p>Yes. In most parts of Northern Virginia and DC, backflow preventer installation requires a plumbing permit and must be performed by a licensed professional. F.H. Furr handles permitting and compliance for you.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">What\u2019s the difference between a backflow preventer and a check valve?<\/h3>\n\n\n\n<p>A check valve prevents water from flowing backward under normal conditions, while a backflow preventer is a more advanced device that protects against both backpressure and backsiphonage \u2014 and is typically required by code.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Backflow can be devastating, introducing wastewater, ground contaminants, and a host of other concerning chemicals and compounds into what should be clean or safe lines.
