Reduced Pressure Zone Assembly Installation in Newark, NJ
RPZ assemblies offer the highest level of protection and are required for high hazard connections like commercial kitchens, medical facilities, chemical injection and car washes. They include two independent check valves with a relief valve that dumps water if either check fails. Because the relief valve can discharge, we plan for drainage and install the assembly above grade where it can be tested. We carry proven brands like Watts, Febco, Wilkins and Apollo.

Reduced Pressure Zone (RPZ) Device Installation in Newark, NJ
For high-hazard applications in Newark, NJ where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is usually required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. GLN Plumbing is experienced with RPZ installation, making sure all components are correctly sized, positioned and set up according to state and local plumbing codes. Proper installation is critical for effective operation.
Pressure Vacuum Breaker (PVB) Installation in Newark, NJ
For low-hazard applications, such as lawn irrigation systems in Newark, NJ, a pressure vacuum breaker, or PVB, is a popular and cost-effective backflow prevention device. PVBs protect against back-siphonage by letting air into the system when pressure drops. Our certified plumbers carefully install PVBs above the highest point of downstream piping, as code requires, to maintain effective protection. We also make sure of proper clearance and drainage.
Understanding Backflow Preventer Installation Costs in Newark, NJ
The cost of backflow preventer installation in Newark, NJ varies with the device type, size, location and complexity of the plumbing changes required. A residential irrigation system and a large commercial water main will be priced very differently. GLN Plumbing provides transparent, upfront quotes after a careful assessment of your property. We aim to offer competitive pricing for high-quality, code-compliant installations that protect your investment and health.
Double Check Valve Assembly Installation in Newark
Double check assemblies are used for low hazard connections such as many fire sprinkler systems and some irrigation lines. They have two spring-loaded check valves and test cocks for annual certification. Unlike an RPZ, they do not discharge water, so they can be installed in vaults or below grade where local rules allow. We size them to avoid excessive pressure loss on your system.
Backflow Testing and Certification in Newark
Most water providers require testable backflow assemblies to be certified at installation and then annually. Our certified testers check each valve's opening point, relief valve operation and differential pressure. If a device fails, we can repair or rebuild it on the spot with genuine parts. We submit passing results so you avoid compliance letters or service interruption.
Backflow Prevention for Irrigation Systems in Newark, NJ
Irrigation systems in Newark, NJ are a frequent source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply. Installing a dedicated backflow preventer for your sprinkler system is often a local code requirement. We specialize in selecting and installing the correct device, such as a pressure vacuum breaker or atmospheric vacuum breaker, to protect your home's main water line from contaminants coming from your landscape irrigation.

Most residential backflow preventer installations can be finished within 2 to 4 hours. More complex commercial systems or installations requiring significant pipe changes might take longer. We always aim to complete the work promptly while keeping our quality standards high.
Backflow is when water flows the wrong way through a pipe and carries contaminants into the clean water supply. It can happen from back siphonage during a pressure drop or back pressure from pumps and boilers.
Most residential backflow preventer installations can be finished within 2 to 4 hours. More complex commercial installations or those requiring extensive pipe changes might take a full day. We always aim for efficient service with minimal disruption to your water supply.
Backflow preventers are installed at cross-connection points where non-potable water could enter the potable water supply. Common locations include irrigation system connections, fire sprinkler lines, boiler systems and connections to auxiliary water supplies, usually just after the main water meter or at the point of hazard.
It depends on the hazard and local rules. Irrigation usually uses a PVB or double check, while high hazard connections like commercial kitchens or chemical injection require an RPZ.
