Description
The Watts LF7R Lead Free* dual check series prevents the reverse flow of water through backsiphonage or backpressure. This ASSE 1024 listed valve is typically used to protect the water supply at the service entrance or at individual, non-health hazard outlets where backpressure may occur.

Features:
  • Forged Lead Free* Brass Body - Forged brass provides strength and corrosion resistance, without the risk of porosity, meaning it can be smaller and lighter than a cast valve
  • Shorter Lay Length - Whether in a meter box or mechanical room, less really is more
  • Variety of Connection Options - Choose from a meter or standard NPT threaded connections
  • Backwards Compatibility - Longer lay length tailpieces give you the option of getting a valve with the same lay length as the most common Watts no. 7 and LF7 valves to make retrofitting a breeze. Valves with the U2L tailpiece are configured to have the same length of the equivalent Watts no. 7 and LF7 series valve:
