In a 2 level house on a slab there is an old floor drain. The basement is dry, it's on high ground with city sewer and excellent drainage. No backups, no problems other than the trap dries out, and allows sewer gas to permeate the basement. The homeowner wishes to have it capped off. Is it OK to get a drain cap and caulk it and tighten it down? She had a contractor look at it and said no problem, just pour concrete into the drain.
Anybody in NC know if it's legal to cap the lowest floor drain fixture in a slab foundation? Thanks all.

Pour RV antifreeze into the drain. It will NOT dry out and will stay there until she has water on the floor draining into the floor drain. At that point, she will be happy she did not seal the drain, and all she has to do is replace the antifreeze.

I wouldn't cap the drain. In the event of a pipe break or leak, the basement can fill up.
Either run a trap primer to the drain, or follow hj's advice and fill it with non-toxic anti-freeze.

If it seems to be evaporating excessively fast, the trap may be cracked and the water may be slowly draining out. I have ran into this problem a couple of times.
Typically around here a giant truck called a stone slinger shoots the pea gravel into the basements. Either the stone hit the pipe as it was shooting out and cracked the pipe, or one of the workers did something to it. It could have been the concrete guys as well.

Yes its legal in NC to cap the floor drain, but I would advise against it.

Install a temporary test plug that can be removed if the drain is needed.

That's assuming you are there to remove it, even if it is under two feet of water at the time.

Thanks, NC. I'm with you.. I'll tell the homeowner it's best to leave it, and put in some rv antifreeze like hj said. The house has been vacant and on the market for a while.
