    This trap is just what we needed. It fits great under our 3 compartment sink. It was very easy to install with basic home depot parts. It is also easy to clean and inspect.

    from Gilpin Market Posted on

    This grease trap is the perfect fit under our 4 compartment sink. It was very easy to plumb with the threaded inlet and outlets. It is built well and should last for years with an easy off cover for cleaning.
