Near the bottom of my hot water tank there is a plastic valve that looks like it is used for draining the water out of it. It has developed a hairline fracture along the length of it and small jets of hot water were shooting out of it.
I've shut off the cold water supply valve and turned off the gas running to the hot water tank. My plan is to drain the hot water tank and replace the valve. However I do not know if this is some sort of special valve and if there is anything extra I would need to do with it's replacement besides just screwing it in.
What kind of valve should I be asking for at my local hardware store and how do I replace this valve?
