Floor Drain Requirement

[texanman]

Hi,
I am not sure if this is the right forum-please advise if not.
Is there any building code that states that a none-residential restroom must have a floor drain? My architect contacts say that they don't know of any.
thanks,

It is going to depend on the building code where the project is located as well as what else is in the building. In Illinois for example, a floor drain in the building is required by the plumbing code:

Required. Any building or structure in which plumbing fixtures or piping is installed in or under a concrete floor to accommodate fixtures on the level of the concrete floor shall have at least one trapped and vented floor drain. When plumbing fixtures are installed on the level immediately above a concrete crawl space, at least one trapped and vented floor drain shall be installed. Additional floor drains shall be required if the installation of fixtures and appurtenances requires the use of floor drains. In a multi-family dwelling, each unit shall have a floor drain if fixtures and appurtenances installed therein require the use of a floor drain.

You might check with the local building inspector or code official

The International Building Code doesn't require floor drains in toilet rooms.

The International Plumbing Code doesn't require floor drains in toilet rooms.

That being said, I always put them in any toilet room that has more than one toilet or has a water heater in/above the room. Depending on the situation, I have put them in the one unit rooms as well.

I have heard too many horror stories of flush valves that break and then flood the entire building. It is a 1" pipe flowing under pressure. Or the relief valve on the water heater releasing. That is a lot of water as well.

PEDARRIN2,

Does the IBC require a floor drain in a building?

BIMR,

Not that I could tell from my search.

He did ask about building codes so I answered with what I have worked with.
