Why do I need my backflow tested?
Backflow assemblies and devices have parts that can break down and wear out, just like the parts on your car. By having the backflow tested annually, you will help to ensure the drinking water supplied to your home or business remains safe. Because backflow assembly parts can break down and wear out, most cities have created by-laws to help ensure the safety of your drinking water. At Metering Services, Inc. we have certified backflow assembly testers on staff, which have attended a rigorous training program and are certified by the ABPA to survey, test, repair, and install all backflow assembly devices.
What is Backflow?
Water distribution systems are designed with the intention of the water flowing in a certain direction– from the distribution system to the consumer. However, hydraulic conditions within the system may deviate from the “normal” conditions, causing water to flow in the opposite direction. Therefore, it is possible (and common) for the water to flow in the opposite direction in unprotected systems. This is called backflow. – ABPA
What is a Cross-Connection?
A cross-connection is an unprotected actual or potential connection between a potable water system used to supply water for drinking purposes and any source or system containing unapproved water or a substance that is not or cannot be approved as safe, wholesome, and potable. By-pass arrangements, jumper connections, removable sections, swivel or changeover devices, or other devices through which backflow could occur, shall be considered to be cross-connections. – ABPA
What is Back Siphonage?
Back-siphonage is caused by mainline piping failures or drafting due to high demands. For example, it is a condition that can occur when the drinking water system pressure drops below that of the fire protection system, drawing the fire protection system water back into the drinking water system. – ABPA
Over time do water meters usually run fast (over-registration) or slow (under-registration)?
From our experience we have found a water meter would be more likely to run slow or under register. A water meter is a mechanical device and it will wear over time resulting in a meter that measures less water than what being used by the homeowner or business.
How can you tell if a meter is operating efficiently?
The only way we know of is to TEST IT.
What are some factors that will affect a meter’s accuracy?
Factors that should be taken into consideration are: The age of the meter, The amount of water measured by the meter, Is this the correct meter for this application, Has the meter been installed properly, Is the meter sized properly, Is there turbulence at the meter, Is a strainer needed, Is there chemical buildup and abrasive materials carried by the water?
