External (Supplied Standard with Endura 7 to Endura 50 Models)
Hub x Hub format – Sch40 DWV. Nominal diameters 2”(Compact), 3” and 4”.
For solvent weld within ABS or PVC DWV drainage systems, use appropriately
approved solvent cement.
Spigot (Sux ‘S’)
Supplied with Spigot format connections for installation
with locally approved Mechanical Joint (MJ) couplings.
Threaded (Sux ‘T’)
Supplied with Female Pipe Thread (FPT) connections. Installed to
Male Pipe Thread (MPT) using appropriate (PTFE) thread sealing tape.

NOTE: The Flow Control cannot be solvent welded
directly to the interceptor. An appropriately sized pipe
stub will be necessary in the event that the FCD is in close
proximity to the interceptor, allowing connection only
with locally approved Mechanical Joint (MJ) couplings.

Tank Connections
Connection of Dishwashing Systems
Air-Balanced Operation
All Endura® Grease Interceptors are manufactured with standard no hub connections
to accept locally approved/accepted MJ (Mechanical Joint) couplings.
This method allows resilience in the connections to prevent stress and a exible means of
integrating metallic or plastic plumbing systems. Should adaption of pipe connection be
required, use appropriate mechanical joint reducers but do not allow decrease pipe
diameter across the unit. (i.e. 3” inlet , 2” outlet.)
Due to regional and local code variation, models with threaded connections (FPT) are available by
adding sux ‘T’ to the part number. Both tank and ow control (TFCD) will be supplied with FPT
connections in this instance based on the respective nominal pipe size. Likewise Endura® Interceptors
can be supplied with spigot format ow controls (SFCD) by adding sux ‘S’ to the part number.
Note: Solvent cement is not an acceptable jointing method from the
piping system to the interceptor. This will result in leakage.
Dependent on the Authority Having Jurisdiction (AHJ), a dishwashing system may be required or prohibited from discharging to
the grease interceptor. Verify with the respective AHJ. Best practice recommends that where a dishwashing system is required to
be connected to the interceptor, that it be serviced by a separate and appropriately sized interceptor, the outlet being connected
to the building drain downstream of the main interceptor.
Where not specied, the dishwashing system is recommended to bypass the grease interceptor, the outlet being connected
downstream of the interceptor outlet. This is based evidentially on the negative impact of commercial detergents and surfactants
that are specically designed to emulsify fats oil and grease making it virtually impossible to separate this material from waste
water discharge. If discharged to the interceptor, the same agents will likewise cause even the most ecient interceptor,
regardless of generic type to work at a signicantly reduced eciency, passing FOG to the downstream system.
A hydromechanical grease interceptor is designed to operate as an air balanced environment. This is vital to the function of the
interceptor and as such no modication or removal of any component parts should be made before, during or after installation
unless specically addressed in the respective Installation & Operation document.
Venting
Unlike Gravity Grease Interceptors, a Hydromechanical Grease Interceptor tank is not required to be directly vented. This would be
detrimental to the function of the interceptor. All connected appliances shall be individually trapped and vented in accordance
with local code requirements. The downstream drain carrying euent to the municipal wastewater system shall also be vented
to atmosphere in compliance with applicable code.
Internal (Supplied Standard with Endura XL75 to Endura XL100 Models)
On Endura XL models the internal ow control is located inside the dynamic inlet bae, axed to the
downstream part that moves forward when the bae is opened. This maintains full accessibility when
operational. NOTE: Internal ow control plate will only be removed when replaced with an external
equivalent of the correct ow rate. Floor below installation can use the
internal ow control as the secondary ow control, the primary ow control being installed
externally as close as possible to xtures.
