Key to hydromechanical function and performance is ow control. If designing for compliance
with PDI-G101 an external ow control(s) SHALL be required as part of the design and
installation. Where acceptable to the Authority Having Jurisdiction, internal means of ow
control can be employed providing that the interceptor is approved to the currently published
version of ASME A112.14.3 –Type C or D. Any method of ow control SHALL be accessible once
in operation for cleaning and maintenance purposes. The Endura® external ow control device
can be recessed into the oor if required. Extension sleeves available. (See Page 5)
Flow Control Location – Indirect Connection:
Some local jurisdictions require warewashing installations to be made on an indirect basis
incorporating an air gap.
An air gap prevents back up of contaminated water into the sinks/appliances in the event of a
system back ow. The ow control device must be incorporated before the indirect connection
to prevent overow occurring during high/maximum waste water discharge. If an air gap is
located within 6” of ow control device*, installation of the air intake tee is optimal. (*Verify
with Authority Having Jurisdiction)
Where required to be installed as an indirect plumbing system, the initial
means of ow control SHALL be installed upstream of the air gap to
prevent overow during xture/appliance discharge.
