6. Unit Maintenance
6.1 Measuring Grease/Solids Levels
Due to its unique design, Trapzilla is capable of retaining high quantities of grease in a compact footprint.
Therefore, unlike traditional interceptors, Trapzilla can hold an extraordinarily high percentage of its
volume in grease without losing separation efficiency. To determine the current levels of grease/solids
in your Trapzilla grease interceptor, follow the instructions below.
1. Remove four nuts/washers securing the 22” Solid Top Cover.
2. Place a grease/sludge dipstick into the center of the opening, making sure that it goes through the
hole in the horizontal baffle.
3. Once the dipstick has found its natural resting place at the lowest point in the conical shaped bottom,
take the measurement.
4. Remove dipstick and compare grease/sludge levels to the corresponding unit in the charts below.

Take solids/sludge measurement from

Take grease measurement from top of
liquid level downward and compare to

Note: Drawing for reference only. Equipment must be installed in compliance with all applicable laws, regulations
and codes, including plumbing codes. Installation should be performed by a qualified plumber.
6.2 Pumping/Servicing Unit
Periodically, the Trapzilla® unit will need to be serviced which involves pumping out all accumulated
grease and solids. Pumping frequency may be set at a regular interval by sewer district (every 30-90
days). If not, determine pumping frequency using instructions in 6.1 to periodically measure grease/
solids levels to determine appropriate timing for pumping. Follow instructions below to pump/clean out
TZ-1826.
1. Each lid has four brass nuts securing the lid. Remove the four brass nuts from the bolts and fully
remove the 22” lid to pump out. It is not necessary to remove adapter lid to pump out Trapzilla.
2. Begin by taking the grease from the top of the main chamber until all grease is removed.
3. Upon reaching the horizontal baffle, you will see a hole through which you may access the rest of
the grease and the solids. Be sure to lower the hose all the way to the bottom of the Trapzilla unit
on the outlet side so that solids may be entirely removed. The conical shape and natural grade of
the unit will allow solids and grease to run to outlet side of unit.
4. Have kitchen run water into unit to flush any remaining solids to the outlet end of the unit.
5. If necessary, use a water hose with spray nozzle to rinse off inside of unit.
6. Secure lids in place and instruct kitchen to run water into unit until full.
DO NOT use mechanical crust breaking devices to break down any mat that has formed inside the
Trapzilla unit.
DO NOT use grinding augers in maintenance of the Trapzilla unit.
