Water heater tee on output

[Steve Conkin]

I would like to add a garden hose connection via a tee connector in the output of a water heater. Can anyone point me in the right direction of what piece I am looking for? Thanks.

You mean a threaded 3/4 brass tee

with a 3/4 inch nipple for the top? Or do you mean a garden hose thread valve that can fit into the side port?
