Additional Details

The 3 inch WATTS LF007-NRS-IOT Lead Free Double Check Valve Assembly is designed to prevent the backflow of polluted water into the potable water supply, specifically at cross-connections identified as non-health hazards by local inspection authorities.

This advanced assembly features integrated pressure-sensing test cocks and a patented ArmorTek® coating for enhanced corrosion resistance, making it suitable for continuous pressure piping applications.

Features & Benefits

  • Lead Free* construction to comply with installation requirements.
  • ArmorTek® coating technology with a patented three-part advanced epoxy system resists microbial-induced corrosion (MIC) and protects exposed metal substrate.
  • Smart and Connected Technology: Integrated pressure sensors at test cocks No. 2, No. 3, and No. 4 measure pressure fluctuations.
  • Modular, Compact Design: Facilitates easy maintenance and assembly by retaining the spring load.
  • Single Top-Entry Cover: Allows for easier in-line servicing without special tools.
  • Replaceable Components: Seats and seat discs are replaceable for extended product life.
  • Low Pressure Drop: Designed for efficient water flow.
  • Fused Epoxy Coated Body: Cast iron body provides robust durability.
  • Top-Mounted Test Cocks: Lead Free* ball valve test cocks for easy access.
  • NRS Gate Valves: Non-rising stem resilient seated gate valves included.

Installation & Use

  • Approved for installation in both horizontal and vertical "flow up" orientations on all sizes.
  • An add-on monitoring connection kit is required to activate the pressure sensors and transmit data to a Building Management System (BMS/BAS) via wired serial (RS-485) interface. Without this kit, the sensors are passive.
  • Always check with local authorities for specific installation, vertical orientation, and testing frequency requirements.

FAQs

What is the primary purpose of the WATTS LF007-NRS-IOT backflow preventer?

Its primary purpose is to prevent the backflow of polluted water from non-health hazard cross-connections into the potable water supply due to backsiphonage or backpressure.

Does this assembly come with monitoring capabilities?

Yes, it features integrated pressure-sensing test cocks at three locations to measure pressure fluctuations. An add-on monitoring connection kit (sold separately) is required to activate these sensors and transmit data to a Building Management System (BMS/BAS).

What type of corrosion protection does this backflow preventer offer?

The cast iron body is protected by ArmorTek®, a patented three-part advanced epoxy coating system. This system is engineered to reduce microbial-induced corrosion (MIC) and protect exposed metal surfaces.

Can this backflow preventer be installed in any orientation?

Yes, the WATTS LF007-NRS-IOT assembly has horizontal and vertical "flow up" approval for installation on all sizes. However, it is essential to check with local authorities for specific installation requirements.

What maintenance features are included with this assembly?

It features a modular, compact design with a single, top-entry cover for easy in-line servicing without special tools. The internal check module seats and seat discs are also replaceable, facilitating straightforward maintenance.
