Is this trap thermoplastic? If not, what model is? I am required by my city to have thermoplastic.

Asked by: nconte
This grease trap is carbon steel, not thermoplastic. We do also carry the poly Ashalnd Polytraps, but they are not specifically designated as thermoplastic. I recommend checking with your city to see if they recommend a particular brand in order to meet code.

Can this unit be installed under ground with cover flush to ground level?

Asked by: tazmanian69
These are designed to be installed above ground. You can put it below ground, flush with the floor, but this will likely cause it to rust and deteriorate sooner. For an in-ground installation, I would recommend a plastic grease trap such as the Ashland Poly Trap -
