Description

The Watts LF009M2-QT-S is a lead-free reduced pressure zone backflow preventer assembly designed to protect potable water systems from contamination caused by backpressure or backsiphonage. This unit is part of the Watts LF009M2 series and is commonly used where a high-hazard cross-connection protection device is required. The assembly includes quarter-turn shutoff valves and an integrated strainer configuration, making it suitable for commercial plumbing, mechanical rooms, irrigation supply lines, industrial water systems, and other applications where reliable backflow protection is required.

This model is marked Lead Free, meaning the wetted surfaces are intended for potable water applications and comply with low-lead plumbing requirements. The visible packaging identifies the unit as a Reduced Pressure Zone Assembly, with EDP# 0122693, NSF-61-372, and a visible barcode/UPC that appears to read 098268643213.

Typical System Use

The Watts LF009M2-QT-S is used as part of a larger cross-connection control system. A complete installation may include:

• Main water service piping
• Upstream and downstream isolation valves
• Reduced pressure zone backflow preventer assembly
• Integrated or upstream strainer
• Test cocks for annual certification
• Relief valve discharge piping or air gap drain
• Pressure gauges for testing
• Service unions or threaded adapters
• Freeze protection enclosure, when installed outdoors
• Drainage provision for relief valve discharge
• Local inspection tag or certification record

Technical Notes

• The arrow cast into the body indicates required flow direction.
• RPZ assemblies must be installed in the correct orientation and location according to local plumbing code.
• Relief valve discharge must not be plugged or capped.
• Installation typically requires enough clearance for testing, servicing, and relief valve drainage.
• Annual testing by a certified backflow tester is commonly required by local authorities.
• The built-in shutoff valves allow the device to be isolated for service and testing.
• The strainer helps reduce debris entering the first check valve but does not replace proper system flushing.
• Pressure loss and flow capacity should be verified against the project specifications before installation.
