Sure, but that can be on the private side of any backflow. From: Sprinklerforum [mailto:[email protected]] On Behalf Of Jeff Normand via Sprinklerforum Sent: Monday, February 03, 2020 12:15 PM To: [email protected] Cc: Jeff Normand Subject: Re: Strainers On the Backflow
NFPA 13 2016 Edition 7.7.6 Strainers. A listed strainer shall be provided in the riser or feed main that supplies sprinklers having nominal K-factors smaller than K-2.8 (40).

The local health and water departments are the enforcing agencies with regard to backflow prevention and cross-connection control, and generally speaking a backflow appliance is only required to be installed on a private connection to the public water system that will supply a non-potable demand. So in 99+% of scenarios, the installation of a strainer would be governed by the serving water agency since it occurs on the public side (and often in the public right-of-way) of the backflow appliance. Questions you have about such equipment should be directed to the cross-connection control department of the water purveyor.

They are included in-so-far as municipalities dictate them. Therefore, the data sheet is the only real refuge for the info. As per yours below, do not use a strainer on our systems.

I found on the backflow submittal where it states it, but is it in NFPA 13 and possibly UFC 03-600-01?
