Commercial building owners must follow state and federal laws when it comes to building code. Sometimes, navigating this, as well as running your business at the same time, can be hard. That is why commercial plumbing experts like those at Hartwig Plumbing & Heating are around to help you keep your plumbing up to standard each year. This includes your backflow preventers.
Types of Backflow
So, what is backflow? If you don’t know the term yet, it refers to water that flows from your pipes back into the city water supply. This is a frequent problem, and contaminated water can spell trouble for the health of local residents. It is important to understand backflow and how to prevent it. There are two main types of backflow; backsiphonage and backpressure. Backpressure happens when interconnections between potable and non-potable water are not properly protected, whereas, backsiphonage occurs due to reduced pressure in the piping.
Backflow Preventing Devices
Luckily, there are devices, often known as RPZs or Reduced Pressure Zones, that can be installed into a commercial plumbing system. An RPZ will protect both onsite drinking water and the city water supply from contaminants due to backflow. Each year, these devices must be inspected and certified to meet commercial building requirements.
Backflow Requirements and Fines for Commercial Customers
Backflow preventers, or RPZs are required in any building with an irrigation system, suppression system, or a large boiler. They should be used in any case where backflow can happen. These devices should be installed before any business is conducted and must be recertified each year to prove they are still working efficiently. If these inspections are not down on time or at all, then fines will apply. That is the last thing we know you want to deal with when running a commercial business. Be sure to talk with your local commercial plumbers about the annual inspection and certification.
