A Beginner’s Guide to Backflow Prevention Assemblies

The tap water we drink reaches our home via the public water supply. Backflow contaminates water and causes diseases like diarrhea, cholera, dysentery, and typhoid. Backflow preventers are specialized devices that help negate such problems. Have your property fitted with one of these devices to guard against avoidable secondary plumbing issues. When it comes to plumbing, always err on the side of prevention.

The information below will help you make the right backflow prevention choice for your property.

• Backsiphonage: It occurs when water changes direction because of a pressure drop. It blocks the main water supply due to which the pipes suck water from an alternate source.
• Backpressure: It’s when the downstream water pressure rises above the source pressure and causes backflow.

To select the right backflow prevention assembly, assess it against the following criteria:

• Range: How much distance would you need your backflow preventer to cover? What is the size of the property? PVBs are suitable for smaller areas, whereas double-check valves and reduced pressure principle backflow assemblies can serve larger facilities.
• Cost: It varies with the backflow assembly’s size and complexity. Therefore, you must choose the device that matches your needs and fits within your budget.
• Maintenance: Complex backflow assemblies require more maintenance. If you plan to buy one of these, be prepared to pay for the extra upkeep and installation costs.
