Backflow Inspector Manchester

Regular Backflow Inspections ensure that your water is safe to use both inside and outside of your home.

 Inspection Company St. Louis

To ensure that the drinking water inside your house doesn't mix with the water your sprinkler system uses to keep your lawn green, you install a backflow preventer. Keeping these two waters from mixing is important because the water used inside your home is held to a different standard of quality than the water you may use for your lawn. Regular inspections of a backflow preventer ensure that the equipment is working as intended and that your water is safe to drink.

Backflow Inspections Manchester

Backflow Preventers are important, and having them be regularly inspected should be part of any home maintenance plan.

Why is a Backflow Preventer Required on a Lawn Sprinkler System?

Backflow valves must be installed alongside irrigation systems to ensure that each water system remains separate. Many different chemicals are used to keep a lawn in excellent shape, and these chemicals can sometimes find there way inside your irrigation system. Water sits stagnant or trapped in these systems, which leads to a build-up of bacteria and increased mineral content.

When your system isn't operating at full capacity, because of a leak, fire hydrant use, or hydrant flushing etc, this can cause an imbalance in your system. When this happens, water from your outside system can back-up into your drinking water. The next time you or a neighbor turns on a faucet for a drink of water, the water received could contain contaminants. How else can this happen? Even minor fluctuations in the city water supply (such as another neighborhood using a large amount of water) can cause imbalances that can introduce contaminants into your water supply.

Having contaminants and bacteria in your drinking water supply can cause serious illnesses and in some cases can even lead to life-threating diseases.

How Backflow Testing is Done - Backflow Inspector Manchester

A backflow preventer keeps your drinking water and your irrigation water separate. Our Licensed Manchester Backflow Testers can perform a backflow test to see if there are problems with your Manchester irrigation systems backflow device. This test includes shutting off water supply to allow for investigation of the plumbing system and observing the valve to see if the water is running backwards (which is good), or if the relief valve opens, which is an indication that it needs to be replaced. After the water direction is checked, the pressure of the system will then be measured. If the water pressure rises as the water flows backwards and seems to be struggling, this could mean that the valve needs to be replaced.

Types of Backflow Preventers - Backflow Installer Manchester

The correct backflow preventer for your irrigation system is going to be dependant upon the size of your system, and the types of situations you may face in your area.

Three of the most common backflow valves are:

  • Double Check Valves
  • Reduced Pressure Zone Devices
  • Atmospheric Vacuum Breakers

Double Check Valves are typically found in lawn sprinklers and fire sprinklers. There is a ball valve on each end of this device that will prevent backflow. Reduced Pressure Zone Devices are commonly used in areas that a city might deem as having “hazardous” backflow. Every city has a different idea of what is hazardous, so it can vary from city to city. This device includes four valves such as an inlet shut-off valve, two spring-loaded check valves, and an outlet shut-off valve. Lastly, Atmospheric Vacuum Breakers have a valve on the inside of the device that prevents backflow. These systems are based on pressure and are placed 6 inches from where the downstream is for your home.
