Backflow Prevention Installation in Bucks County & Montgomery County, PA

Irrigation Systems

Underground sprinklers can draw pesticides, fertilizers, and soil bacteria back into the water supply if pressure drops while the system is charged. This is one of the most common residential backflow risks.

Fire Suppression Systems

Stagnant water in fire sprinkler piping can contain bacteria and sediment. Without backflow protection, this water could contaminate fresh supply during pressure fluctuations.

Commercial Equipment

Commercial and industrial processes often use chemicals, coolants, or other substances that could be catastrophic if they entered the water supply. Backflow protection is essential.

Boiler Systems

Boilers with automatic makeup water connections contain treated water with chemicals that shouldn’t enter the potable supply. Backflow prevention isolates these systems.

Pressure Vacuum Breaker (PVB)

The most common residential backflow preventer, typically used for irrigation systems. PVBs protect against back-siphonage (but not back-pressure) and must be installed at least 12 inches above the highest sprinkler head. Cost-effective for appropriate applications.

Common uses: Residential irrigation systems, hose bib connections, outdoor water features

Spill-Resistant Vacuum Breaker (SVB)

Similar to PVB but designed to minimize water spillage during normal operation. Used where standard PVB water discharge would be problematic—near walkways, above finished areas, or in cold climates where dripping creates ice hazards.

Common uses: Irrigation in sensitive locations, areas prone to freezing

Double Check Valve Assembly (DCVA)

Uses two independent check valves in series, protecting against both back-siphonage and back-pressure. Suitable for low to medium hazard situations. Can be installed below ground in vaults, making it popular for irrigation where above-ground installation isn’t practical.

Common uses: Commercial irrigation, fire sprinkler connections, medium-hazard commercial applications

Reduced Pressure Zone (RPZ) Assembly

The highest level of mechanical backflow protection. Uses two check valves with a relief valve that opens to atmosphere if either check fails. Required for high-hazard situations where contamination could cause serious health effects. Must be installed above ground.

Common uses: Commercial/industrial with chemical hazards, medical facilities, car washes, boiler connections, food processing

Irrigation System Installation

Most municipalities require backflow prevention when installing underground irrigation systems. This is typically required before the irrigation contractor can complete the installation and is your responsibility as the property owner.

Swimming Pool or Hot Tub

Pool and spa fill lines connected to potable water often require backflow protection to prevent chemically treated water from entering the drinking water supply.

Fire Sprinkler Systems

Residential and commercial fire suppression systems require backflow prevention at the point of connection to isolate the sprinkler piping from the potable supply.

Commercial Equipment

Commercial and industrial equipment using water—particularly equipment involving chemicals, processing, or cooling—typically requires backflow protection appropriate to the hazard level.

Boiler Systems

Boilers and hydronic heating systems with automatic makeup water connections often require backflow prevention, especially for larger systems or those using chemical treatment.

Medical and Dental Facilities

Healthcare facilities have numerous potential contamination sources and typically require comprehensive backflow protection at multiple points.

Water Authority Requirement

Your water authority may determine during a survey that your property requires backflow protection that doesn’t currently exist. Compliance within a specified timeframe is typically required.

Failed Device Replacement

When an existing backflow preventer has failed beyond repair, replacement with a new device is necessary to maintain protection and compliance.

Upgrade Requirements

Sometimes regulations change or hazard assessments are revised, requiring upgraded protection. A device that was compliant when installed may need to be replaced with a higher level of protection.

Property Purchase

When purchasing a property with existing systems that require backflow protection, you may need to install devices that should have been installed previously but weren’t.

Accessibility for Testing

Backflow preventers must be accessible for annual testing. This means adequate clearance around the device and access without special equipment or confined space entry. Poor accessibility makes testing difficult and expensive.

Height Requirements

PVBs and SVBs must be installed at least 12 inches above the highest downstream outlet (like the highest sprinkler head). RPZ assemblies must be above grade and typically 12-36 inches above ground. DCVAs may be installed underground in vaults.

Relief Valve Drainage (RPZ)

RPZ assemblies discharge water when the relief valve operates. They must be installed where this discharge won’t cause problems—not over electrical equipment, in flood-prone areas, or where freezing could create hazards.

Protection from Damage

Devices must be protected from physical damage, vandalism, and environmental hazards. This may mean bollards near driveways, enclosures in public areas, or weather protection in exposed locations.

Insulated Enclosures

Insulated covers or enclosures protect exposed devices from freezing while maintaining accessibility. Various enclosure types are available for different climates and device sizes.

Heat Trace

For high-risk installations or devices that must remain operational year-round, electric heat trace can prevent freezing inside the enclosure.

Winterization

Irrigation system backflow preventers can be drained and winterized if the system is shut down seasonally. Proper winterization prevents freeze damage that would require expensive repairs.

Indoor Installation

When possible, installing backflow preventers in heated spaces—basements, mechanical rooms—eliminates freeze concerns entirely.

Typical Requirements

Most municipalities require a pressure vacuum breaker (PVB) or equivalent protection for irrigation systems. The device must be installed on the supply line to the irrigation system, typically near the house where the irrigation line originates.

Coordination with Irrigation Contractor

If you’re having a new irrigation system installed, we can coordinate with your irrigation contractor. They install the irrigation system; we install the backflow preventer. Timing coordination ensures efficient completion.

Winterization

Irrigation backflow preventers should be winterized along with the rest of the system. We can show you the procedure or include winterization in seasonal service.

Swimming Pools and Hot Tubs

Pool fill lines connected to potable water need backflow protection. Requirements vary by municipality—some require it for all pools, others focus on permanent fill connections.

Fire Sprinkler Systems

Homes with fire suppression systems typically need backflow protection at the sprinkler connection. Requirements depend on the type of sprinkler system and local codes.

Boiler Makeup Water

Hydronic heating systems with automatic water makeup may require backflow prevention, particularly larger systems or those using chemical treatment.

Fire Suppression Systems

Commercial fire sprinkler systems require backflow protection at the fire service connection. The type of device depends on the sprinkler system type—wet, dry, or chemical—and the hazard classification.

Commercial Irrigation

Large irrigation systems for commercial properties typically require double check valve assemblies or higher protection, often installed in underground vaults for aesthetic reasons.

Medical and Dental Facilities

Healthcare facilities have numerous potential contamination sources—dental equipment, lab processes, sterilizers, dialysis equipment. Multiple backflow preventers may be needed at different points of use.

Food Service

Restaurants, commercial kitchens, and food processing facilities often require backflow protection on equipment connections and may need whole-building protection depending on hazard assessments.

Industrial Processes

Manufacturing, chemical processing, and industrial operations typically require RPZ assemblies for high-hazard protection. Multiple devices may be needed for different process connections.

Car Washes and Automotive

Automotive facilities use chemicals, degreasers, and wash solutions that are hazardous to water supplies. High-hazard backflow protection is typically required.

Annual Testing

Most jurisdictions require backflow preventers to be tested annually by a certified tester. Testing verifies the device is still functioning properly and hasn’t degraded over time. We provide ongoing testing services and can keep you on a schedule so you don’t miss deadlines.

Compliance Reporting

Test results must be submitted to your water authority, typically within a specified timeframe. We handle report submission as part of our testing service, ensuring your compliance is documented properly.

Maintenance and Repairs

Backflow preventers are mechanical devices that can wear out. Internal seals and springs may need replacement over time. If your device fails testing, we can often repair it and retest during the same visit.

Winterization (Seasonal Systems)
