Product Overview

The Watts LF7R Lead Free* dual check series prevents the reverse ow
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.
Shorter. Lighter.
More Compact.
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:
* The wetted surface of this product contacted
by consumable water contains less than 0.25%
of lead by weight.
