Question

alernate to floor sink


I am installing a commercial prep kitchen. It has a drain in the usual 2' from floor. My health department says I need a Floor drain. He also said there are alternatives to the standard floor drains. I need to know how I can do it. I need a 3 compartment sink, a hand washing sink and a mop sink. I am desperate please help me!

Typical commercial sinks do not use P-traps---the 'free fall' into a floor drain with its own P-trap

There is often a funnel like extension on the floor drain--to accommodate more than one sink or water source.

The free fall sink drains are cut on an angle so there is an air gap above the funnel---

We need more info--is your kitchen on a concrete slab?

Are the building drains cast iron--PVC or copper?

Is a licensed plumber required to perform this work?

Stop right there.
Go back to the Health Dept guy and ask him to explain himself fully
and to provide the trade name and/or piping schematic of what meets code there.

If he was referring to alternatives to a GREASE TRAP... they exist.
But they do NOT substitute for the floor drain.

Good advice.
I'm a little confused though. Are we looking for a way to drain food prep sinks and DW sinks? In my neck of the woods we install floor sinks. Or are we talking about floor drains?

I think that *we* are talking about floor sink(s)...
which will (usually) tie into a floor drain system like 99.987% of restaurants (with all the hosing down etc) in the world have.

That's what I was picking up here too.

By UPC your food prep sink (along with many others of which I'm not sure what all you have in the building) has to drain by indirect waste. I've only been plumbing for 5 years, but i've never seen any other way of doing it around here besides a floor sink, so I don't know what alternatives he's talking about.

We go through his constantly, heath inspector ask for one thing then the plumbing inspector shows up and wants another, when we get these type of job we get the requirement in writing from the health department, then we draw the proposed layout and isometrics have the chief plumbing official sign off on the plan pull the permit and do the work, that way there’s no he said she said. A kitchen drain system can get tricky, floor drains, floor sinks, indirect drains, grease trap capacity, reseal on independent floor drains, venting, etc ,my advice is to find a local plumber that has commercial experience. Get someone competent so you only have to pay once.
