That meter and strainer should not be installed between the #1 shutoff valve and backflow preventer there after, as approved backflow prevention assemblies are classified, approved and supplied as a complete assembly with direct inlet and outlet shut-off valves. However you likely would have had to shut down the supply from the water meter in order to make the correction.

Yeah I inherited it when it needs to be replaced I will correct it. For now they don't want to spend the money. It's original so was approved at some point by an inspector
