Pressure drops can be caused by water leaks, water service interruption, a water main break, or hydrant flushing. The RPZ valve registers pressure drops and redirects potentially toxic water before it can contaminate your drinking water.

Some Champaign-Urbana plumbing systems must be fitted with a reduced pressure zone (RPZ) valve to comply with local codes. Also called a backflow preventer or a backflow device, the valve helps keep your drinking water contaminant-free.

The backflow device must be tested every year by a licensed plumber with a Cross Connection Certification license. This certification is legally required for contractors who perform work on RPZ valves. Older systems must be retrofitted with an RPZ valve as well.
