A reduced pressure zone valve (RPZ) is simply a form of backflow prevention device used to safeguard drinking water against contamination. Backflow prevention products are typically classified into three groups: an assembly, a device or a method. Aside from elimination, these are basically the only ways to keep backflow from developing. Backflow assemblies ordinarily have two durable isolation valves with properly situated test ports. These assemblies have the distinctive benefit of being in-line serviceable and they can be tested and fixed without the need to take out an installed assembly. Particular accredited courses are applied to testing and repair backflow assemblies and only certified testers – like the experts at Test Pro Backflow Services – can conduct testing.
Committed and Cost-Effective Backflow Preventer –Â RPZ Valve Naperville
When working correctly, RPZ Valve Naperville can remain effective for a long time. A reduced pressure zone setup consists of a valve for inlet shut off, a pair of check valves separated by a pressure relief valve and an outlet valve. RPZ assemblies can be purchased in a variety of designs that are:
- * Appropriate for either above or below ground installation
- * Horizontal installation is usually necessary unless the unit is configured for an alternative
- * Safeguards against back-siphonage and back-pressure
An RPZ Valve Naperville is considered adequate for hazardous applications where the consequence of backflow into the potable water supply could cause significant risk. They’re viewed as effective mainly because they stop back-pressure and siphonage due to their design and because they can be tested to verify proper function.
RPZ Valve Naperville are often chosen rather than an air gap because the head loss over the valve is far less. These efficient devices contain a couple of check valves which have a pressure monitoring chamber between them. The chamber maintains a pressure that’s lower than the water supply pressure yet still high enough to be useful. The lower pressure is sustained by a relief valve that lowers extra pressure inside the chamber by releasing it into a drain. Four testers enable confirmation of proper functioning by the valve with a pressure gauge.
An example of when backflow would present a risk to the drinkable water supply would be when the using of well-washing chemicals inside below ground sewer pump stations. Occasionally, untreated sewage could contain hazardous gases that could even cause concrete to break down. Well washers are utilized to clean contaminated concrete walls of a well. They are usually installed with RPZ Valve Naperville in case a pumping station fails and causes sewage levels to rise over the well washer, resulting in backflow moving down water supply lines.

RPZ valves are tested with an instrument known as a differential gauge which uses hoses connected to the testers on the valve. The gauge checks to ensure that the valve’s springs are functioning appropriately.
