We Can Prevent Backflow in your Home or Office

Backflow is the flow of water or other substances in the reverse direction from which it was intended to flow in your plumbing system, and this is usually due to a change in water pressure.


Backflow is a serious issue since it can lead to the contamination of drinking water or other significant hazards to public health. It's therefore essential to have proper backflow prevention devices installed and maintained by a professional.


Amanda Plumbing is the only name you need to know for the finest backflow prevention services. Our licensed team knows just what to do to eliminate any backflow situation for your kitchen or bathroom. Feel free to ask us any questions as to how we handle the matter. We're available 24 hours a day.

Signs That there's a Backflow issue

  • Foul odors coming from your drains or faucets
  • Changes in water pressure
  • Discolored water (brownish, rusty color)
  • Bubbling or gurgling sounds from your toilet bowls, sink, or shower drains

Backflow Prevention Devices

Backflow preventers are devices within the plumbing system that keep the flow of water moving in the proper direction. They act as barriers to prevent contaminants from entering a community’s potable water supply. Backflow preventers are often located in the cross-connections that link clean water to the applications in which it is used.


Amanda Plumbing has multiple backflow certified technicians capable of installation and repair as well as performing the yearly testing of your backflow preventer.

Backflow Preventor Annual Testing

Because of its mechanical nature and the fact that many irrigation backflow preventers for irrigation systems are located outside in Ohio, the systems are prone to failure. In order to protect the quality of the city’s water supply, a backflow test is required to be performed by a licensed professional every year. Our team is qualified to test your system and make any required repairs.


Best of all, we take care of all of your paperwork when we are done. We will ensure the city receives your annual testing and remind you when you are due again next year.

Why you need a Backflow Prevention Device

When water enters your home from the main water supply line, it should only ever flow in one direction into your home.


But sometimes, due to pressure changes in the pipes, the water can actually flow backward and seep back into the main water supply line.


  • For example, backflow can happen when there is a break in the main water line or when a fire hydrant is opened for use. Because pressure is lost during these events, water is no longer being pushed forward into your home and will flow backward into the city water lines.

    When this happens, backflow can contaminate the public drinking supply with:

    Fertilizers/pesticides
  • Human waste
  • Chlorine from pools/spas
  • Soap from sinks/dishwashers/showers

How do I know if I need Backflow Prevention System installed at my house?

First off, any Delaware of Franklin County resident who has an irrigation system or a well is required to install a backflow preventer (because both systems are at risk of contamination due to backflow)


Live elsewhere? Or are you a resident without an irrigation system or well? If so, you’re probably wondering if you need a backflow prevention device installed at your home.

Well, we still recommend you have a backflow preventer installed anywhere incoming water and wastewater might be cross-connected.


Newer homes may have built-in backflow preventers on certain water lines but in order to know for sure whether your home has proper backflow preventers set up, we suggest having a plumber inspect your home’s water system. They’ll install backflow preventers where it’s needed.
