How to Install a Grease Trap

If you are trying to save money and you are going to try to install your own grease trap we can help. The very first thing to do to install a commercial grease interceptor or grease trap is to install the trap as close as possible to fixture that is being serviced. Then make sure you always install the traps where you have east access to the cover for easy removal and cleaning.

The flow control has to be installed as close as possible underneath the fixture. Then the flow control has to be installed with a vent or an air take on the downstream side of the orifice plate. Then the vent connection has to be positioned at the top of the flow control fitting and then it is to be piped going upwards and higher than the source of the water itself or the building's vent system.

Then plumbers recommend that a cleanout tee be installed before the flow control so it can get to the flow control orifice to clear any debris that may get stuck. The cleanout plug should really be installed over the outlet of the grease trap.

The grease trap should be installed by using a no-hub coupling. The outlet piping should be connected to the sanitary drain. The size of the pipe should be equal or larger than the inlet piping. The outlet piping will also be vented so that the grease trap could not be siphoned in any way.

Lastly, solid waste should not be allowed into the grease trap. Food grinder waste and other solid matter will be captured in the sink or by the solid interceptor (which is different than a grease trap) before it hits the grease trap.
