Backflow Preventer Brands We Install in Clarksburg
GJK Plumbing works with leading backflow preventer brands known for reliability and durability. We commonly install devices from manufacturers such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our experience with these brands means you receive a high-quality, long-lasting solution built to withstand the water conditions and pressures in Clarksburg plumbing systems. We can also advise on models that best fit your budget and application.

Pool and Spa Fill Backflow Protection in Clarksburg, WV
An auto-fill line or hose connection on a pool or spa creates a straight path for chlorinated water to reach the supply. We install the correct device on pool fill lines and check that hose bibbs have vacuum breakers. This simple step protects your household water and keeps you in line with local code. We can add the work when a pool is being built or renovated.
Reduced Pressure Zone Assembly Installation in Clarksburg, WV
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.
Pressure Vacuum Breaker (PVB) Installation in Clarksburg, WV
For low-hazard applications, such as lawn irrigation systems in Clarksburg, WV, a pressure vacuum breaker, or PVB, is a common 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 check for proper clearance and drainage.
Code-Compliant Backflow Installation in Clarksburg, WV
Navigating the plumbing codes for backflow prevention in Clarksburg, WV can be challenging. GJK Plumbing stays up to date with local and state regulations so every installation is fully compliant. West Virginia builds its plumbing standards on the International Plumbing Code, and the state licenses plumbers who do the work. From proper device selection and placement to required permits and inspections, we handle every part of code compliance. Your system works as intended and avoids fines or expensive rework down the line.
Double Check Valve Assembly Installation in Clarksburg
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 Clarksburg
Most water providers require testable backflow assemblies to be certified at installation and then once a year. 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 right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Reduced Pressure Zone (RPZ) Device Installation in Clarksburg, WV
For high-hazard applications in Clarksburg, WV where toxic substances could contaminate the water supply, a reduced pressure zone, or RPZ, device is often required. RPZ backflow preventers offer the highest level of protection, using a relief valve to discharge water if the pressure drops. GJK Plumbing specializes in 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.
