What is Backflow?

The fundamental takeaway on backflow is this: you don't want it. The rest you can leave up to us. Backflow is unsanitary water or sewage that is flowing in the opposite direction - back from where it came. It's literally flowing back towards its source. It's a problem that can occur anywhere in your plumbing where pipes back that are going in opposite directions intersect or cross-connect, typically when there is a drastic change in water pressure, such as a burst pipe.

Your home installed sprinkler system includes a system of underground pipes laid strategically throughout your property. In between uses of your sprinkler system, water sits in these pipes, ready to eject when the sprinkler system runs next. This is fine for watering your landscape, but this water becomes less desirable for other uses as it sits underground. Pesticides, fertilizer, and other lawn care chemicals could reach the system, and water that sits stagnant in these pipes becomes a hot spot for bacteria and mineral buildup.

When a change in pressure occurs, you are in danger of contaminated water from your sprinkler system entering the water source of your kitchen and bathroom taps and showerheads. As you can imagine, backflow is unsavory at best and a severe health hazard at worst. Mineral-heavy water can damage your home, give your tap water a bad taste, irritate your skin, and potentially cause illnesses that may even become life-threatening.

The Backflow Testing Process

Backflow testing should be done any time you suspect there is an issue with your backflow preventer, and at least once a year as a regular annual check-up.

When you book an appointment for backflow testing, you will want to know what to expect. We are happy to explain how your sprinkler system and plumbing work, but ultimately what you need to be aware of when anticipating a backflow testing appointment is that your water will have to be shut off. It is a relatively painless process for you as a homeowner, provided you plan ahead and make the necessary arrangements or adjustments in your schedule to account for the brief length of time when you won't have access to your water supply.

When you schedule professional backflow testing with a licensed lawn sprinkler servicer like Lawn Sprinklers of St. Louis, expect a brief 20 to 30-minute visit. The focus will be on the device known as a backflow preventer. A backflow preventer is an essential component to any plumbing system, including your sprinkler system. It is a mechanism that keeps you safe from the risk of dirty water flowing into your home.

When our licensed technicians arrive at a property to perform backflow testing, they perform tests and observe your backflow preventer and the flow of water to make sure that the backflow preventer is doing its job. Specifically, they will:

  • Verify that the check valves on your backflow preventer are properly functioning to prevent backflow.
  • Ensure that air ports are in working order, openning completely when necessary.
  • Check that the relief valves open before the pressure at the check valve reaches less than 2 psl below the pressure at the inlet device.

If this all sounds foreign to you, don't sweat it. When you rely on the professional services of the sprinkler experts at Lawn Sprinklers of St. Louis, you don't need to understand your sprinkler system or identify its parts. Our technicians have years of experience providing exceptional service in lawn sprinkler installations, inspections, and repairs. Our dedicated service members are equipped with extensive training and all the necessary equipment to perform safe and effective backflow testing.

Why You Need Backflow Testing

  • It is required
  • It keeps us safe
  • It makes repairs easier

In Missouri, as in most places, backflow testing is required for homeowners who have a sprinkler system installed. According to the Department of Natural Resources, anyone with an irrigation system must have their backflow testing done annually by a certified backflow testing professional. You will receive a notice from your city when your annual backflow testing is due. Contact a licenced backflow testing professional like the technicians at Lawn Sprinklers of St. Louis. We will take care of the rest and ensure you are in compliance.

Your backflow preventer has an enormously important job. A lot is riding on its performance, including the health and safety of you and your family. Complications with backflow can arise from seemingly minor occurrences, such as a difference in water pressure caused by different volumes of usage between neighbors, and much more severe instances of disfunction such as a water main break. Even minor contaminants or a small amount of contaminated water backflow can pose a serious risk to your health. Backflow testing prevents these issues from taking hold and catches weaknesses in your preventer before a problem occurs.

The certified backflow testers of Lawn Sprinklers of St. Louis are as familiar with backflow testing as they are with all other types of lawn sprinkler and irrigation maintenance and repair. When we visit your property for backflow testing, we will inform you if there is a need for any repairs or parts replacements. Since we are a full-service lawn sprinkler company, it's easy to schedule follow-up service or even take care of the problem then and there.
