Backflushing Instructions: Crispin Sewer Valve

Source: Crispin Valve
The Sewer Air Release Valves must be backflushed periodically because of the nature of their application. Valves on systems which pass liquids bearing high solids content are backflushed to remove settled solids from the valve body, as well as to prevent scum and debris from building up on the valve mechanism.
