Some backflow prevention assembly testers have developed the theory that if a small assembly malfunctions and does not test out, they just replace it. The tester does not even make an attempt to repair the assembly. In most instances, all that it takes is a crescent wrench to remove the cap, or a screwdriver to remove four screws. To remove and clean a check valve on a small assembly is less than a five-minute process.

Testers need to realize that a malfunctioning assembly should not mean automatic replacement. The approval process of assemblies requires them to be repairable in-line. If it becomes a trend for testers to replace every small assembly without trying to repair it, we could see enforcement agencies cease requiring tests and just require the customer to replace the device every couple of years.

Why make customers spend money on test cocks and shut off valves, if all it does is give the tester a reason to replace the assembly? The customer is being charged from $50 to $75 to test a small assembly, which he could replace with a backflow preventer for a lot less. This also prevents having to shut off valves and test cocks.

Additionally, testers should carry the various parts for small assemblies on their trucks. This would save a trip back to the site when parts are necessary. Testers must make every effort possible to satisfy enforcement agency requirements in a cost-effective manner, otherwise, the overall cross connection program will suffer the consequences.
