Default Adding three sink to washer drain

Attached are two pictures for existing plumbing to the washing machine and crude picture of adding three new drains for three additional sinks.

We need to add one hand sink, one mop sink and one large 3 compartment sink.

Any advice or recommendations if this would meet building codes in Texas and if there is a simpler way.



· Adding new Y connector and moving existing washer drain up higher to make room for drains running underneath.

· Use existing Y connector for hand sink

· Adding new Y connector below for mop sink

· Adding new Y connector at bottom for large 3 compartment sink

· All three sink, hand sink, mop sink and 3 compartment sink will have vent tied into to existing roof vent using T connector

· Washer drain since at top of stack will continue to use root vent



Questions:



· I assume each drain must be separated?

· Are separate vents needed for each of the drain lines?

· Is it ok to use T connector for the vents where they connect to drain?

· For the drains close to the bottom of the floor, is there a minimum height for the drains to be above the floor?

· The Y connector at the main drain pipe, is it ok to stack four Y connectors?

· With this many drains running into one pipe is there a minimum size the drain must be?

· Is there a simpler way to design this and meet building codes?

What is this for? A commercial kitchen or restaurant? When you say "mop sink" do you mean laundry tub? Also, it already appears that you will exceed the recommended volume for the 2" pipe (vertical fixture units).

Yes, commercial kitchen, we need to add three sinks, hand sink, mop sink and large 3 compartment sink.

Do you see any way we can make this work?

I am not familar with building codes, is the exceed recommended volume for 2" pipe a recommendation or something that will fail build codes?

As far as my codes are concerned, no, it won't work the way you want it to. Primarily, where is your grease trap? The proper pipe size and installation is a code requirement and believe me when I tell you that you don't want to run a commercial kitchen that is not piped properly. It's best to get somebody on the job sit to make a recommendation.

Hire a plumber, there are many codes that you need to know about... not second hand stuff, you need to KNOW how to run this piping. 2" drain, too little, no grease trap, wrong piping type ( inmortant to use the right kind in commercial drain ). andBeing that Im also a gasfitter I suppose its worth saying that you NEED to hire one of us to make sure you dont have mega problems with your intake air and ehaust hoods.

I agree. That won't work. That's what you call wet venting and not recommended.
Nice cut and paste job though.
