Flow Meter - Winterization
We recommend that a qualified licensed contractor perform this type of winterization
method. The blowout method utilizes an air compressor with a cubic foot per minute (CFM)
rating of 80-100 for any mainline of 2" or less. The compressor is attached to the mainline
via a quick coupler, hose bib, or other type connection, which is located beyond the
backflow device. Compressed air should not be blown through any backflow or flow meter
device. For additional winterization procedures, we highly recommend contacting the local
dealer for the most common local practices. In the event you need to blow upstream from
where the flow meter is located, we recommend bypassing the meter by temporarily using
one of two options.
