Question about bathroom sinks

self

[rudy45]

Friends of ours moved into a home recently. To my surprise, when I went to a bathroom, I found that the sink had NO overflow protection. Wouldn't you know it, a few days later, I learned that someone had stopped the sink but left the faucet running. The overflow caused damage to the ceiling below the bathroom.

I called Home Depot and they said the only sinks they sell are ones WITH overflow protection.

Are there any code requirements regarding overflow protection for bathroom sinks? Thanks.

There's a code against beating the person who stopped up the sink and left the faucet running.

CODE RED

Most all codes would be local.

Some might be statewide but would only apply to new construction or possibly to remodel jobs.

If the owner did it himself, you might be SOL.

I think the key is 'don't leave the faucet running with the drain stopper in'.

The sinks I've noticed without overflows have drains that don't seem designed to accept stoppers. Does someone actually make sinks that accept stoppers but don't have overflows? That seems silly.

BTW, even if an overflow can't keep up with a full-on faucet, an overflow that actually exists can keep up with a leaking faucet.

Also, a design I've not noticed in any new sinks but which I have seen on old sinks and bathtubs had a vertical pipe next to the sink/tub with a stopping-pipe in it. It's a little hard to describe, but the net effect was an overflow which sat entirely outside the sink. It wouldn't work if someone plugged up the drain hole (which was designed not to accept a plug) but would work if someone used the stopping-pipe as intended.
