Do Endura® XL tanks need to be directly vented?
The practice of venting a grease interceptor directly is typically related to Gravity Grease Interceptors (GGI). Unless specically
mandated by local code or bylaw, with no variance allowed, a Hydromechanical Grease Interceptor (HGI) DOES NOT require
the tank to be directly vented. Venting is however required on the downstream drain the same as most plumbing appliances,
xtures to allow eective and unrestricted discharge of euent.
Do I need to install a clean out before or after an interceptor?
Most plumbing codes require an upstream and downstream cleanout immediately before and after the interceptor. This is
good practice and gives positive indication of which outlet is in use.
Do I have to install the Flow Control Device?
For an HGI, the Flow Control is ESSENTIAL to the high performance operation of the interceptor. It must be installed as
indicated and without it the interceptor is no longer meeting the requirements of its appropriate approvals. This is not
acceptable to the AHJ and they should be asking for the installation to be rectied before approval is granted.
My jurisdiction requires euent sampling via a
downstream access. What do I do?
As an HGI approved to National performance Standards, although common for GGI (Concrete, Steel) Endura® XL DOES NOT
typically required a separate sampling location. For those jurisdictions that do require the capability to sample, Endura® XL
incorporates a sampling port within the outlet assembly. This is accessed by the simple removal of the air balance/sample
port cap (See Page 16) allowing water quality samples to be taken for analysis.
What can be connected to an interceptor in respect of
wastewater discharge?
A grease interceptor UNDER NO CIRCUMSTANCES will receive sanitary wastewater discharge – i.e. that from WC ushing for
example.
Wastewater discharge to a grease interceptor will be from foodservice activities only, its application being to separate non
petroleum Fats Oil and Grease from waste water.
The requirements for appliances and xtures that must and must not be connected to a grease interceptor is typically
dened by your local plumbing codes and or jurisdictional by-laws. You should consult a licensed plumbing professional
or your local city plan check or plumbing code ocials for clarication regarding right schedule of maintenance for your
application/premises.
How often should an interceptor be cleaned?
Cleaning of an interceptor is a case by case situation. Each facility will have many dierent factors impacting need for
maintenance and cleaning. A licensed contractor will have the experience and equipment necessary to help establish the
right schedule of maintenance for your facility.
How much will it cost to maintain my Endura® XL installation?
In terms of comparison Endura® XL units are signicantly more compact (less internal volume) than their equivalent
Gravity counterparts. As pumping is typically charged by the volume of gallons removed the ongoing maintenance will be
proportionally less too. Rates will vary signicantly by region and by contractor. Always use a licensed or approved contractor
to maintain your interceptor
