I need some advice. I am looking at opening a shop. I have the location but it has not had a commercial kitchen in it before. I contacted our city hall/code enforcement office. (keep in mind that this is small town, 25,000, thats run on a even smaller town attitude) They don't have a clue. They don't even have a book I can look at. So I called the 3rd party office that does the inspections for this city. Spoke with a really nice guy that said yes I do need one (knew this) but that I could put in one under the sink. I am only going to be draining the 3 compartment sink, no floor drains or anything. Now I googled purchasing these things and they are pretty cheap (like $400!!). It seems like it's all too good to be true. THoughts??

The plumber charged me $350 to install it, so be sure you factor that in. I also do catering and I was able to get a small under-the-sink one, too.

I think it's only big restaurants that need an underground one outside that costs like $15,000 .... for what we do, the under-sink works fine.

The grease trap depends on your local waste water rules and regulations. I have to get an inground, even though an under counter one is more suited to my needs.

Giiiiirl......tell me about it. My rent is SUPER cheap though...so it's a question of...move two blocks north to be out of the city limits...but pay four times in rent...or stay with the place that is super cheap, on a busy road...and "invest" in a grease trap...that the city takes ownership of and won't even be mine! LOL

i was kinda scared i was gonna have to get an inground too...but the under the sink one was ok....the plumber made me one for about 500.00 installed.

cheap rent rox!....it'll be worth it in the end, geeze i hope it's not 8K though!!!!seems like a lot of the cost of some of these plumbing things are digging the hole, wonder if you could get a better deal if you dig the hole?...i saved like 3K digging a big long ditch myself.
