Backflow Testing and Certification in Exeter
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 right away with genuine parts. We submit passing results so you avoid compliance letters or service interruption.

Reduced Pressure Zone (RPZ) Assembly Installation in Exeter
RPZ assemblies offer the highest level of backflow protection and are often required for high-hazard applications in Exeter. These devices feature two independent check valves and a relief valve that opens to discharge water if pressure differentials indicate a backflow condition. FVR Plumbing specializes in precise RPZ installation, with proper sizing, placement and testing to meet all regulatory requirements for residential and commercial properties. We work with trusted brands like Watts and Febco.
Pool and Spa Fill Backflow Protection in Exeter, NH
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 (RPZ) Device Installation in Exeter, NH
For high-hazard applications in Exeter, NH 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. FVR 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 Exeter, NH
For low-hazard applications, such as lawn irrigation systems in Exeter, NH, 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.
Code-Compliant Backflow Installation in Exeter, NH
Navigating the plumbing codes for backflow prevention in Exeter, NH can be challenging. FVR Plumbing stays up to date with local and state regulations so every installation is fully compliant. Inspection practices differ from town to town, so confirming local requirements before work begins saves time. 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 costly rework down the line.
Double Check Valve Assembly (DCVA) Installation in Exeter
The double check valve assembly, or DCVA, is a widely used backflow preventer for low-hazard applications where the consequences of backflow are not severe. In Exeter, DCVAs are frequently installed on fire sprinkler systems or irrigation lines. Our certified plumbers carefully install these devices, making sure both check valves operate correctly and are properly sealed to prevent backpressure or back-siphonage into the main water supply.

Double Check Valve Assembly Installation in Exeter
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 too much pressure loss on your system.
