If the hot water heater is gas be sure it's turned off same if it's electric so you don't burn out theelements in the tank, I would advise you to buy some plumbers putty and pull the drain scre out and put putty in it then reinstall the screw. all the ones I looked at I could not tell by looking to see where the drain was and if it has like a hose bib on it or not. also pull the screw all theway out and see if you got some sand in the valve and if so use some compressed air in a can to blow the stuff out of the seating area of the screw. Hope this is helpful would be nice to have a picture of the drain.

You can buy a replacement relief valve at any hardware or home improvement store. It's real name is a T&P valve or temperature and pressure relief valve. It always has a 3/4" inlet and outlet. It is a very easy procedure to replace. You will need a bucket, teflon pipe thread tape, and a 3/4" x 6" black iron or galvanized pipe nipple. To start the valve replacement, turn off the shuttoff valve on the cold water line. Then open the handle on the relief valve and drain water into the bucket, that is, unless you have a pvc pipe coming off of it into a drain floor, then just drain it without the bucket. Be careful, the water is hot! When the water level gets below the relief valve, it will stop draining. Then remove the pvc pipe, if applicable, and thread in the 6" pipe nipple to use as a leverage tool to remove the valve from the water tank. Turn it counter clockwise to remove. Then put teflon tape on the new valve, going from left to right with the valve threads facing downward. Wrap about 3-4 layers all around the threads. Then twist the new valve into the water tank clockwise and using the pipe nipple tighten by hand until very snug and outlet is facing downward, as before. Remove the pipe nipple and install pvc pipe, if applicable. Leave valve handle open and turn on the cold water until the valve starts spitting, then close the relief valve and let it fill up the tank. If you did it correctly, you are now finished! Good luck!

GE uses MMYY as the first four digits of their serial numbers. That unit was manufactured in August 2001.
FYI, a nice little page on decoding water heater manufacture can be found here.
