We drained our hot water heater a couple of months ago, and we have had low hot water pressure ever since. Any suggestions?

My guess would be, the valve that was turned off on the water supply did not open up all the way when it was turned back on. Make sure the valve is all the way open, if that not it then the supply valve needs to be replaced.
