We handle everything from small residential devices to bigger systems.

Reduced Pressure Zone (RPZ) Device Installation in Severn, MD
For high-hazard applications in Severn, MD 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.

Proper installation is critical for effective operation.

Irrigation systems in Severn, MD are a common source of backflow, as stagnant water and lawn chemicals can be drawn back into the potable water supply.

We are experienced 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.

Frequently Asked Questions About Backflow Preventer Installation in Severn
The cost for backflow preventer installation in Severn, MD typically ranges from $400 to $1,500, depending on the type of device, its size and the complexity of the installation. A basic residential PVB for an irrigation system is generally on the lower end, while a commercial-grade RPZ assembly costs more because of material and labor requirements.
An RPZ, or reduced pressure zone device, provides the highest level of protection and is used for high-hazard applications where contaminants could be toxic. A DCVA, or double check valve assembly, is used for low-hazard applications where contaminants are non-toxic. The choice depends on the risk of contamination at the cross-connection point.
Constant dripping or discharge from an RPZ relief valve, low pressure downstream and a failed annual test are common signs. Visible corrosion or a cracked body from freezing also means service is needed.
We commonly install high-quality backflow preventers from trusted brands such as Watts, Wilkins by Zurn, Apollo and Conbraco. Our plumbers are experienced with a wide range of devices and can recommend the right option for your application and budget.
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, often just after the main water meter or at the point of hazard.
Most residential backflow preventer installations can be completed within 2 to 4 hours. More complex commercial installations or those requiring extensive pipe changes might take a full day. We always aim for prompt service with minimal disruption to your water supply.
Yes, BVL Plumbing stands behind our work. We offer a warranty on our backflow preventer installations, covering both the workmanship and the installed device. Specific warranty details will be included with your quote and invoice, giving you peace of mind.
Signs of a failing backflow preventer include discolored or foul-smelling water, a noticeable drop in water pressure, visible leaks around the device or water discharging from the relief valve on an RPZ. If you notice any of these, call us for an inspection in Severn.
