Reduced pressure zone assemblies, also known as RPZ valves, are extremely important. They’re used to keep contamination or pollution out of your water. Specifically, these devices are installed onto your plumbing system to help protect both drinking water and the city water supply.

Backflow prevention assemblies are designed to prevent contaminated water from mixing into clean municipal water supplies, which are usually used as drinking water. Contaminants like sediments, bacteria, and fertilizer are a major public health hazard, so there are regulations in place that require certain buildings to have backflow preventers installed.

Backflow preventers are commonly installed in buildings where clean water cross-connects with any of the following installations:

If something happens that causes a drop in pressure in the water mains, such as the use of a nearby fire hydrant or a burst pipe, contaminants can flow back through the sprinkler head because of the pressure difference. This can introduce fertilizers and pesticides into potable water.

The State of Illinois requires that every backflow device be inspected annually by a certified backflow tester, and every city that operates a public water system is responsible for making sure that this is done. Why is backflow testing required? The purpose of a backflow system is to protect the quality of drinking water.

A Reverse osmosis (RO) system is a water filtration process in which water flows through a semipermeable membrane that separates the water from contaminants such as chlorine, lead, fluoride, nitrates, and more, providing clean and safe drinking water. Typically, a standard RO system features multiple filtration stages, including a sediment filter, an activated carbon filter, and other specialized filtration components to ensure optimal water quality.

Backflow prevention devices are most common in commercial settings, but some residences may also need one. One of the most common reasons for a residential backflow preventer installation is a home sprinkler system that cross-connects with the drinking water system.

Installation typically involves connecting the system to your home's water supply and placing the filtration unit under the sink or at a point of use. You can install a reverse osmosis system on your own. If you are not accustomed to installing RO systems, we recommend seeking professional assistance.

You may have one of these in your yard or home, or maybe seen one in your neighborhood, and wondered about it. It is commonly known as an RPZ valve or a backflow preventer.
