Expert RPZ Testing in Mount Prospect, IL

RPZ testing is a required annual service for Mount Prospect properties with irrigation systems, boiler fill connections, or fire suppression systems. The Village of Mount Prospect runs a Cross-Connection Control Program and requires that test results be submitted to the Public Works Department each year. Tests must be performed by a licensed plumber who holds a Cross-Connection Control Device Inspector (CCCDI) certification. At RH Shudy Plumbing, our certified plumbers locate your RPZ assembly, inspect it for corrosion or visible damage, and use calibrated differential pressure gauges to test each check valve and the relief valve. If the assembly fails, we can repair or rebuild it on site. After a passing test, we file the required certification report directly with the Village through the BSI Online reporting system, so you stay on record and avoid compliance issues. Mount Prospect properties with lawn irrigation are especially common candidates for this service, and many property owners are unaware the annual testing requirement applies to them. Call RH Shudy Plumbing to schedule your RPZ test in Mount Prospect.
