The Watts 3/4" Water Pressure Reducing Valve with built-in backflow prevention helps regulate incoming water pressure between 25–75 psi. Designed for residential and commercial systems, it supports up to 400 psi max working pressure and features NPT union x NPT female connections for easy installation.

Product Specification:

• Inlet/Outlet Size: 3/4 inch NPT Union x NPT Female
• Adjustable Pressure Range: 25–75 psi
• Max Working Pressure: 400 psi

Key Features:

Built-In Backflow Prevention: Prevents reverse water flow to protect your supply from contamination, ensuring safer plumbing operation.
High Pressure Tolerance: Handles up to 400 psi working pressure, suitable for residential, commercial, and irrigation systems.
Adjustable Pressure Control: Allows precise regulation of downstream water pressure from 25 to 75 psi for consistent flow.
Threaded NPT Connections: Features union x NPT female threading for a secure, leak-free fit and easier maintenance or replacement.
 Brass Body Construction: Made from durable lead-free brass for corrosion resistance and long service life in various environments.

How it Works:

The Watts 3/4" water pressure reducing valve connects to your plumbing system using NPT union x female threads. Once installed, it automatically reduces high inlet water pressure to a safer, adjustable downstream level (25–75 psi), protecting pipes, fixtures, and appliances. The integrated backflow preventer stops water from flowing in reverse, safeguarding your water supply. Its internal spring and diaphragm mechanism respond to pressure fluctuations, providing stable water flow and reducing wear on the plumbing system over time.

FAQs:

Can I install this valve vertically?

Yes, it can be installed vertically or horizontally, but performance is optimal when installed horizontally with the spring bonnet upright.

How do I adjust the pressure setting?

Use a wrench to turn the adjustment screw on the top of the valve—clockwise increases, counterclockwise decreases the pressure.

Does this valve need regular maintenance?

It’s low maintenance, but periodic checks and cleaning of the strainer screen are recommended to ensure performance.

Is this valve compliant with lead-free plumbing codes?

Yes, it is made from lead-free brass and complies with NSF/ANSI 61 and 372 standards.
