What does the Texas Plumbing Code or UPC say about overflow prevention in bathroom sinks?
Question:Does anyone know if this it is acceptable in the state of Texas (Houston to be specific) or as part of the UPC Plumbing code to not have overflow prevention at bathroom vanity sinks? Or, does anyone know where i can find the part of the codebook to reference this question.
My bath vanity sinks do not have an overflow prevention. If i turn on the faucet and plug the drain, it will overflow. The Powder room pedestal sink has 3 small homes on the inside of the sink bowl on the fornt lip where if the water level reaches, it will drain out the sink drain. The Master bath and others with a vanity cultured marble cabinet top sink do not have these. I am trying to figure out if this is acceptable, I have googled everything i can think of. TIA.

I have noticed that many sinks no longer have overflow holes. I have to assume that the overflow was never in the code. I have not seen it addressed. The new vessel sinks that are becoming popular are one example. I have never seen a kitchen sink with overflows either.
They really don't care if you overflow your sink, they are just concerned with a proper air gap between the faucet and the sink so you don't contaminate the water supply. Sorry.
