“You’re Going To Have The Water Off How Long?????”
How many times have we heard such a statement when testing or repairing containment backflow prevention assemblies on critical services?
Through the years of enforcing San Antonio Water System’s Backflow Prevention Program and today actually being involved in the testing and repairing of assemblies, we have always had to deal with many critical services not having manifold installations (by-pass arrangements). With manifold installations, one Backflow Prevention Assembly can be turned off at a time for testing and/or repair. If the installation does not have a manifold backflow prevention assembly, the water has to be turned off to the facility. The only exception is if there is an additional belted water service or source to the facility.
