Backflow Systems

What Are Backflow Systems?

Backflow systems are integral and mandatory in most plumbing systems to ensure that waste and contaminated water does not enter the local supply of fresh, potable water. They are installed right before a building's connection to a water main line, and proper operation is necessary to keep that water line from any contamination whatsoever.

Backflow occurs when said waste water 'flows back' into the incoming supply of potable water, and can be the result of a number of plumbing issues that have previously gone unnoticed or unresolved. Due to the severity of a backflow occurrence, most jurisdictions and water districts demand a functioning, regularly-inspected backflow system.


All backflow devices are inspected annually, per all water districts.

Complete Fire Protection specializes in inspections of ALL types of backflow devices. There are reduced pressure backflows, doublecheck backflow devices, Pressure Vacuum Breaker (PVB) backflow devices and Air Gaps. The different types of devices that we inspect include but not limited to WATTS, AMES, WILKINS, WATTS, CONBRACO, HERSEY, etc...

During our comprehensive inspection, we test and verify the integrity of each constituent component of your backflow system, and may also perform maintenance on those components that need repair or replacing. Post-inspection, we forward the results of our tests and findings to the respective water department and the customer. This forwarding is done automatically within Complete Fire, and requires no additional input from the customer.
