What to Expect When Having Your Backflow Preventer Inspected

March 14, 2020

It’s always important to do everything you can to avoid backflow and all of the problems that come with it. Any time you have non-potable water that flows back into the public water supply, this becomes a major health risk.

You need to have a backflow prevention device installed on your irrigation system to prevent backflow from occurring. It’s important to regularly test your system for backflow, and to have your backflow inspection conducted by a certified technician in Altoona, PA.

But what exactly do these inspection appointments entail? Here’s a quick overview of what you can expect when you call in a professional to inspect your backflow preventer.

Device options

The kind of equipment that will be checked depends on the type of backflow prevention system you have in place. There are a couple main options people generally choose from when first installing a system: a reduced pressure principle device, or a set of double check valves. Either one of these pieces of equipment will have a mechanical backflow preventer built in, which provides a physical barrier to any backflow that could potentially occur.

If you are to prevent backflow siphonage, which is the reversal of normal flow in a septic system or irrigation system, you’ll need to have professionals analyze the pressure in your home’s plumbing and see if there’s a potential danger of backflow siphonage occurring.

The frequency with which you need to have your device inspected will vary from case to case depending on the age of your system, the kind of equipment you have and whether or not you’ve ever experienced any problems with or risk of backflow. If you know your backflow prevention device requires annual inspection, you should make sure you have a working relationship with a professional who is licensed in backflow prevention and who has worked in your area before so they understand the local water system.

During testing, the certified technician will shut off the downstream shutoff valve and then wait a few minutes before testing the pressure in the system with test kit hoses. The technician’s main purpose at this point is to find any areas in the system where the pressure isn’t reading at the levels it should be.

Even if you don’t believe you’re having any issues with backflow, it’s still important for you to have your systems checked on a regular basis as a means of preventative maintenance. This will help you make sure contaminants from fertilizers, pesticides, herbicides, animal feces and more are not getting into the drinking water. Again, keeping up with backflow prevention and inspecting your systems is a matter of public health—you owe it to yourself and everyone who lives around you to do everything you can to prevent backflow from becoming an issue.
