The Watts Lead-Free Brass Residential Dual Check Valve Backflow Preventer is designed to prevent the backflow of contaminated water into the potable water supply, offering reliable protection against back-siphonage and backpressure at service entrances or individual outlets and providing peace of mind that your water is safe from impurities.
Its construction from durable, corrosion-resistant lead-free brass not only ensures compliance with stringent industry standards - making it safe for use in residential water systems - but also provides a reliable, maintenance-free service life. The plastic replaceable check valves and stainless steel springs can be accessed and serviced without the need for specialized tools, ensuring that the preventer remains in optimal working condition with minimal effort. Furthermore, this 1/2" x 1/2" preventer is able to handle a broad pressure range, with a minimum working pressure of 10 psi (69 kPa) and a maximum of 175 psi (12 bar).
Equipped with union female NPT inlet and outlet connections, the installation of this backflow preventer is straightforward and secure. These connections provide a tight, leak-free seal, which is crucial for preventing backflow and maintaining system integrity. The two plastic replaceable check valves also work in tandem to block any reverse flow of water, ensuring that only clean, potable water reaches your home.
The compact design of this preventer makes it adaptable to a variety of setups. Meeting the ANSI/ASSE Standard 1024, this versatile backflow preventer is approved for residential water system containment and continuous pressure applications and can be installed in either vertical or horizontal orientations.
