Grease Interceptor
FEATURES
Wade 5000-5100 series interceptors are PDI (Plumbing & Drainage Institute) certified. All are
equipped with a one-piece cover secured with machine screws. A soft elastomeric gasket is
attached to the body of the interceptor to prevent odor from escaping. An air relief is provided to
eliminate siphonage and each unit is furnished with a flow control device to insure it will perform to
its rated capacity.
OPERATION
Waste water draining to the interceptor passes through the flow control device which regulates the
velocity to a controlled rate. As water enters the interceptor, the baffle arrangement reduces
turbulence to allow efficient separation. The grease, as separation occurs, floats to the top and is
accumulated. The waste water, relieved of contaminates, continues to flow through the trap and into
the drainage system. See diagram.

INSTALLATION
Install the interceptor as close as practical to the fixture(s) being served. Avoid installations where long runs of pipe
(exceeding 25’) are necessary to reach the interceptor. This precaution will preclude the possibility of grease becoming
congealed in the pipe before it reaches the interceptor.
The unit may be placed on the floor, partially recessed in the floor, recessed with the top flush with the floor or encased
below the floor in an appropriate housing to accommodate piping and structural considerations. Whatever the installation
method, anticipate sufficient clearance to remove the cover and baffle for cleaning. Verify that no obstructions will be
placed over the interceptor after installation. A minimum clearance equal the overall height of the interceptor (excluding
any extension) is recommended.
Do not install the grease interceptor in a waste line from a garbage grinder.
Garbage grinder waste must bypass the interceptor because the rapid accumulation of solid matter will significantly
reduce the rated efficiency of the interceptor. In an application where solids will be present, a solids interceptor should
be used.
A separate grease interceptor is recommended for each commercial dishwasher.
The size is determined by the discharge rate of the dishwasher as stated by the manufacturer.
Placement of a grease interceptor in a high traffic area is an important concern. If the unit is to be installed flush with the
floor, it is necessary to load rate the interceptor cover. The standard Wade interceptor is designed for pedestrian and
light traffic only. If heavy loads are anticipated, the interceptor must be specified with an appropriate reinforced cover. An
extension is frequently used to increase the rough-in dimension from the inlet/outlet centerline to the finished floor. The
extension anchor flange is not adequate to support the entire interceptor. For installations at flush-with-floor
level, the interceptor chamber must rest on solid ground or a concrete pad. For upper floor installations, (suspended
above the lower floor ceiling), the interceptor must be independently supported on hangers suitable to carry the entire
weight.
A single interceptor serving multiple fixtures is recommended only where the fixtures are located close together. In these
installations, each fixture should be individually trapped and vented.

FLOW CONTROL
The flow control device is designed with an integral orifice to achieve a predetermined optimum flow rate, thus
eliminating turbulence and to regulate surges in the drainage line. The orifice opening in the flow control device is related
to the size and flow rating of the grease interceptor. The standard orifice sizes are for gravity flow conditions where no
pressure buildup is anticipated. If an interceptor is operating at maximum flow levels, a pressure head may develop,
which may cause an overload condition.
Using the supplied flow control device is an important factor in the operation of the grease interceptor. The flow control
device must be installed in the waste line upstream of the grease interceptor. Typically, the device is placed beyond the
last connection from the fixture(s) and as close as possible to the underside of the lowest fixture. When two or more
sinks or fixtures are combined and served by a single interceptor, a single flow control may be used.
The supplied flow control device must be properly vented to permit air to mix with the fluid entering the interceptor. Air
facilitates the separation and, more Importantly, is necessary to maintain optimum pressure, thereby maintaining the
proper operating level within the interceptor chamber.
The flow control air intake may terminate under the sink drain board as high as possible, to prevent overflow. Another
method is to terminate the vent outside the building. It is recommended that the installer check with the local plumbing
code authority.
VENTING
Grease interceptors must have a vented waste, sized in accordance with code requirements for venting traps, to retain a
water seal and to prevent siphoning.

Factors Affecting Grease interceptor Performance
Velocity of Incoming Water
A higher velocity of water will contribute to turbulence and slow the grease separation process, thereby reducing
efficiency. Installation of additional flow control devices at all the sources of flow may be required.
Grease to Water Ratio
Higher ratios of grease particles to the water will the lower the efficiency of the interceptor – If high ratios of water to
grease are anticipated, increase the size of the interceptor one or two units.
Detergents in the System
Degreasing agents or grease cutting detergents will break down the liquid grease into minute particles that can cause
slower separation time, thus allowing these particles to pass through the interceptor. Increasing the size of the
interceptor will allow longer retention rates and improve the efficiency.
Flow Capacity
If maximum recommended flow rates are exceeded, the efficiency of the interceptor will be decreased. Either install
additional flow controls devices at all sources of flow, or install a larger interceptor.
Specific Gravity of Filtrates
Grease has a lower specific gravity than water and will separate and rise to the surface quickly. If the waste water has
food particles or solids having a higher specific gravity than water, these filtrates will accumulate at the bottom,
eventually passing out of the interceptor. If high concentrates of solids are anticipated, the installation of a solids
interceptor is recommended.
Installation Location
The interceptor should be located as close as possible to the source of grease. Piping to the interceptor could become
clogged if the liquid cools prior entering the interceptor.

MAINTENANCE
General Considerations
Design and installation are key factors in the operation of a grease interceptor; however, without a disciplined
maintenance program, efficiency and performance can be adversely affected. If adequate maintenance is not performed,
excessive grease buildup will occur until the water ladended with grease passes directly through the unit. Regardless of
design efficiency or installation, grease interceptors perform only as well as the maintenance schedule allows.
Cleaning (5000 and 5100 Series)
The frequency of cleaning is determined by the use load factor and the capacity of the installed interceptor. An ideal
cleaning cycle can be established after the unit has been in operation for several weeks. A logical cleaning schedule is
normally determined by checking the unit after a normal shift, or following a period of peak usage. Grease removal
intervals may vary from once a week to once in several weeks. Never clean an interceptor during a time when customers
are present, as the offensive odors may develop inside the interceptor. Cleaning can easily be performed by following
the steps listed:
1. Loosen and remove the fasteners securing the cover to the interceptor body.
2. Gently pry the cover from the body being careful not to damage the gasket seal.
3. With the cover removed, skin the grease from the inside and place in a disposable container. Never dispose of
the contents in any part of the plumbing system.
4. Remove the baffle assembly and sediment basket (if so equipped) and clean.
5. Remove accumulated solids from the bottom.
6. Replace internal components and secure the cover.
7. Periodic inspections of the flow control orifice are suggested.

Cleaning (5103 Series) Semi-Automatic Interceptor
To assist in the maintenance and cleaning process, Wade offers a unit incorporating a top draw-off port for grease
removal. The cover has an accumulating hood to capture the liquid grease and funnel into the draw off port. Cleaning
can easily be performed by following the steps listed:
1. The interceptor in normal use has the control valve off and the drain port plugged. When cleaning is required, run a
full stream of hot water through a fixture serviced by the interceptor. This will liquefy the grease for extraction. A
period of two minutes is required.
2. With the hot water supply shut off, turn the in-line closure valve to a fully closed position.
3. Remove the bronze plug from the cover and insert the hose fitting and flexible draw off hose, tightening the hose
fitting securely. Place the end of the hose into a container suitable for disposal.
4. Turn the hot water supply back on back on and allow the water pressure to steadily force the liquefied grease
through the hose. Caution: The liquid grease may be hot when exiting the draw-off hose; take care to keep the water
flow as laminar as possible to prevent grease spilling.
5. Once grease is no longer visible at the discharge end, turn the water supply off. Properly dispose of the grease.
Never dispose of the contents in any part of the plumbing system.
6. Remove the draw-off hose and fitting and replace the bronze plug.
7. Fully open the in-line control valve.
8. Periodic inspections of the flow control orifice are suggested.
9. A bi-annual inspection of the internals of the interceptor is recommended. Inspect and clean the baffle assembly and
thourghly clean the body of all solids and debris.

EXTENSIONS (Bolt-On & Integral)
Extensions should be specified on grease and oil
interceptors when the interceptor is buried in the ground,
vertical adjustment of the interceptor is necessary to
meet the drainage piping, and/or floor level access
requirements. Extension heights range from four inches
to any maximum practical for serviceability. Extensions in
excess of 20" are not recommended. One must consider
the slope of the drainage piping from the fixtures to the
inlet of the interceptor. Typically, allow a slope of ¼" per
foot in the drainage pipe. Therefore, there will be many
installations, especially with large interceptors, where
the sloped drainage pipe ends up below the inlet
connection. An extension is added to the top of the
interceptor so that the inlet can be lowered to meet the
incoming drainage pipe and the lid of the interceptor can
be extended to floor level.
Wade offers three different kinds of extensions: integral,
bolt on and cover shrouds. An integral extension is
specified by expanding the "H" dimension on the
interceptor. The "H" dimension is from the center of the
inlet and outlet to the top of the interceptor. One would
specify a "H" dimension to meet the job requirements
and the interceptor will be manufactured to that
specification. The extension is incorporated into the
production of the interceptor to produce a seamless,
integral interceptor.
A second method of providing an extension is a bolt on
design. In this example, a top is manufactured out of the
same material as the body. The extension is secured to
the body by means of bolts bearing against its base
flange, compressing the sealing gasket to complete the
union. The regular lid is bolted to the extension top in the
same manner as it would be to the body of a standard
interceptor.
SHROUDS
Cover shrouds incorporate either standard or draw-off
grease interceptors mounted on adjustable elevation
cradles in either open or closed bottom housings with
non-skid floor level lids. The cover shroud is adjustable
and is recessed into the slab to house the interceptor.
Cover shrouds are particularly important where below
floor level installation of draw-off grease interceptors is
required, because such models cannot be installed
independently with tops at the finished floor level.

EXTENSIONS (Adjustable)
In installations where the exact extension dimension required is unknown or where little notice has been provided to the installer
advising of the need for an extension; integral and bolt on extensions are impractical due to the time necessary for their fabrication.
Wade’s nationwide network of manufacturer's representatives stock adjustable extensions for immediate shipment to jobsites when
these situations occur. The extension is adjustable and is secured to the interceptor similar to a fixed extension. After bolting the
extension to the interceptor, the top is adjustable to grade.
Installation Note
If adjustable extension is install in areas other than on grade where fumes may seep from the adjustable extension connections, an
optional rope seal is recommended. The 1/2” diameter neoprene sponge gasket is installed in the annular space between the upper
and lower housings. For the slotted openings, it is recommended that these spaces be sealed with a elastomeric flex seal tape with
good adhesion characteristics. For slab on grade installations where it is desirable to seal the housing from back-fill, an aluminum foil
duct tape is suitable.
