Backflow Service Providing Exceptional Service Since 1921

Des Plaines Backflow Service

Serving Businesses throughout Cook County

The Safe Drinking Water Act requires backflow prevention assemblies installed in areas where there are potential hazards of cross-contamination of potable water. Annual testing is required to ensure the device is functioning properly. If you need one scheduled, Bishop Plumbing, Heating and Cooling, Inc. provides comprehensive backflow service in Des Plaines and throughout Cook County.

Contact us at (847) 380-8053 to book an appointment for backflow testing.

How Backflow Happens

Backflow occurs when contaminated water reverses direction. This can be caused by back pressure or back siphonage, which happens when the pressure in the pipes exceeds the pressure coming into the pipes. Negative pressure in a pipe is known as back siphonage. Regardless of the cause, backflow can contaminate drinking water and result in potential health hazards.

Backflow Prevention

Our licensed plumbers are dedicated to protecting the public health. We can perform a detailed assessment to determine if your home or business is susceptible to backflow. We can recommend backflow assemblies that are suitable for your property. While homes may benefit from these devices, two types of backflow assemblies are required for businesses.

These include:

  • External backflow assemblies – These assemblies are designed to prevent cross-contamination of the city water from a property.
  • Internal backflow assemblies – This is designed to protect the drinking water on your property from a hazardous cross connection.

All our new backflow device and assembly installations are covered by a one-year warranty for parts and labor.
