Backflow Prevention

Trust the Backflow Prevention Experts

Backflow prevention is an essential aspect of plumbing services that ensures your drinking water remains safe and free from contamination. MD Plumbing understands the importance of backflow prevention and offers a range of services to keep your water supply safe.

Why Is Backflow Prevention Necessary?

Backflow is a situation where the water flows in the opposite direction, causing contaminants to enter your plumbing system and pollute your drinking water. This can happen due to various reasons, including a sudden drop in water pressure, a break in the water main, or a backflow from an irrigation system.

How Does a Backflow Prevention Device Work?

A backflow prevention device is installed in your plumbing system to prevent the backflow of water from contaminated sources. It works by allowing the water to flow in one direction only, preventing any backflow from occurring. The device is installed at the main water supply point or at individual fixtures to ensure maximum protection.



There are two types of backflow prevention devices: 


  • The pressure vacuum breaker works by creating a vacuum in the device when water flows through it. 
  • The reduced pressure zone device works by creating a barrier between the contaminated water source and your plumbing system.

When Should You Get Backflow Testing?

It is recommended that backflow testing be done annually to ensure that your backflow prevention device is functioning correctly. A malfunctioning device can lead to contaminated water entering your plumbing system, causing serious health hazards.
