If External Backflow Prevention is needed
If your local plumbing code requires or additional backflow prevention is required external to the handwash
system, the following backflow preventers are suitable and approved for use with our systems. Two units will
be required for each system, one on each the hot and cold inlets.
Consult local and national codes: conformity and compliance to local and nation codes is the responsibility
of the installer. Consult your local plumbing code for specific details for your location and use a certified
plumber for proper installation.
