After lots of backflow testing, your preventer failed inspection. Is it worth the fix?
To understand the importance of a failed backflow inspection, we must first look at the importance of your backflow preventer working properly.
Like the name suggests, your backflow preventer is key to preventing the backflow of contaminated water from flowing back into the clean water supply.
As you can imagine, it is extremely important that your backflow preventer assembly performs optimally at all times! Backflow preventers that do not work properly can lead to property damage, injuries, and even death. In the worst backflow incident on record, over 1500 persons became ill and 98 persons died.
Annual backflow testing by certified plumbing experts ensure any potential issues are identified and remedied before harmful incidents occur. If your backflow assembly fails inspections, that means that a repair or replacement is needed immediately!

Why Did Your Backflow Preventer Fail Inspection?
Listed below are four common reasons why your backflow preventer may have failed inspection.
#1. Broken Check Valves
There are two check valves that need to be inspected. The first check valve needs to open properly at certain water pressures and the second needs to stop water from leaking past it. If either valve is broken, your backflow assembly will not function properly.
#2. Leaking From The Relief Valve
A leaking backflow preventer will harm your inspection, and this leaking stems from the relief valve opening point. If your relief valve opening point is too high it can allow internal pressure in the system to exceed the minimum threshold. If the opening is too low it cannot function properly, usually due to corrosion. In either situation, the backflow preventer will leak, endangering your clean water.
Debris caused by installation or repairs to the mainline can cause failures in your backflow assembly. For example, if the water company does repair work on a water system, sometimes small pieces of pipe can become lodged between the checks or poppits, causing the checks not to seal.
#4: Worn Springs
Backflow preventer springs can become worn with age and need to be repaired.
