Grease trap
Restaurant grease trap: a thick grease cap was almost gone in under a month on PRO-PUMP®.
Taco John’s, West Fargo · West Fargo, North Dakota, USA · 10 November 2026
The challenge
The trap was called out as heavily impacted. Grease had reduced the working size of the separation chamber and was obstructing the flow. A photograph on 19 November 2003 shows a thick grease cap.
The approach
PRO-PUMP® was set up from a 5-gallon pail on an automatic pump, so the trap was dosed continuously. One pail was a month’s supply.
Results
Thick grease cap, 19 Nov 2003
Before
Almost no cap, 11 Dec 2003
After
Under a month
Time
PRO-PUMP®
Product
Within a month the owners could see the difference, and the 11 December photograph shows the same trap with almost no grease cap. They kept PRO-PUMP® on as a regular dose. Ecological Laboratories present this as that restaurant’s result. It names PRO-PUMP®, so it is not used as a DGTT claim.
