Backflow Testing Denver

Backflow occurs when clean drinking water becomes contaminated with wastewater. This happens with a reversal in water flow, which is caused by backpressure or backsiphonage.

When the water pressure in your plumbing system is greater than the water pressure in the city’s main line, backpressure occurs. When this happens, contaminated water from your plumbing line enters the municipal system and affects the water quality of the surrounding area.

Backsiphonage is similar: when there is a change in water pressure (often caused by a water main break or a fire hydrant being opened incorrectly), contaminated water will flow in the opposite direction and mix with the city’s potable water supply.

This is why it’s essential to have the proper backflow prevention systems in place.

Although backflow prevention systems are most often installed in commercial buildings, some residential properties are also required to have these systems in place—particularly if your home features cross-connections between your plumbing system and the municipal water line.

Properties featuring the following systems will be required to install backflow prevention assemblies:

• Irrigation systems (lawn sprinklers)
• Fire suppression systems
• Pools or ponds
• Commercial-grade boilers (typically found in multi-family buildings)

The above water systems can potentially result in cross-connections and introduce contaminants such as chemicals, chlorine, pesticides, and even human waste into the community’s potable water supply.

Bell Plumbing, Heating, Cooling & Electrical is here to help you install the right type of backflow prevention assembly to help your property remain in compliance with county regulations. We can provide you with county-approved backflow devices, including:

• Double check assemblies
• Double check detector assemblies (fire suppression)
• Lead-free reduced pressure principle assemblies (residential water lines)
