Condensation floor pipes

[bbqbrisket]

I have been told that condensation pipes need to be installed in both a laundry room and HVAC room.

The the requirements are that the approx 3 inch looking floor drains are to be about 1 inch above floor tile grade.

Why can't they be recessed or sloping into the drain?

Need some more info:

Project location: code section?: & definition for "condensation floor pipes"

It appears you may be dealing with "floor drains", please clarify.

Unusual that your floor drain is going to be 1" above floor tile grade, clarify why as most floor drains are flush to floor tile grade as typically required by plumbing codes.

Maybe 'condensate' and not condensation?

HVAC typically has a condensate drain, though I don't get elevating the receptacle for it, and I don't understand having one in the laundry room....

An air gap between the condensate pipe and the drain would make sense, though I'd have to look for a Code Section if one exists.

As noted by jdfruit above, location would help as there may be a local or state amendment.

bbqbrisket, Welcome to the forum.

It sounds like they are asking for the condensate drain to stop 1" above the floor drain as an air gap.

Could you provide more details, preferably the Code Section you need to comply with?

This is a common correction picked up at final inspection. International Plumbing Code 802.1.5.

Are we sure that this is not what used to be referred to as a "Hub drain"? The hub of the fitting was raised above the floor surface so that other waste water did not readily go into that system. Oft times they were used on an independent system that went to daylight or the storm drainage system as opposed to entering the sewer system since it it is basically clear waste water. If it is a floor drain, then it is required to have a grate over it so that other material did not go into the system.

Until we get some more specific information from the OP,

we are not really sure about anything.
