When a significant layer of grease has accumulated the trap must be cleaned out. If grease escapes into the sewer, it can cause a number of problems. Many types of grease and wax can solidify at low temperatures and form plugs in the line, forcing workers to clear the plumbing line after it starts to clog.
Grease traps are designed to separate and capture waste grease and solids before they enter the waste water. They are used to reduce the amount of FOG that enters the main waste water system.
All grease traps consist of a large tank. Water from the drain flows into the tank and settles. Solids sink to the bottom, while lightweight grease floats to the top; leaving clear water in the middle. The water flows through to a second tank and discharges to the sewer system through a small pipe. Many have baffles or screens to trap debris and large chunks of material as they flow into the tank.
To stop blockages and keep grease traps in optimal working condition, it is important the right solution is used.
