Hi Sue,

Draining your hot water tank isn't the same as flushing it. It sounds like you have allowed mineral build up from the pipe walls and heater to enter the hot water system. The faucets will have to be opened up and checked and cleaned and the hot water system will have to be flushed clear. If you have heat trap mipples on the water heater that's where I'd start. In the mean time here's how to flush and maintain your heater.
For long life and fewer troubles you should keep your heater clear of mineral build-up by flushing on a regular schedule. Attach a hose to the boiler drain at the bottom of the tank. With the pressure on, open the boiler drain and let it run untill the water runs clear. You will see a spurt of red,(rust) followed by white grains,(lime or calcium carbonate). This shouldn't take more then a few minutes. Do this monthly to keep it clear. Now flush out your hot water lines on ALL fixtures. Now pull each aerator and clean the screens. Be sure you put them back togather the same way you took them out. Don't forget to flush it out every month. Your heater will thank you for it. Hope this helps, Tom

I have the same problem but I don't have faucet aerators to trap sediment and my shower head flows freely with COLD water on. The hot water is the only one affected. Can tank sediment reach the outlet piping from the hot water tank? If so what can I do to clear it out? I have opened all faucets fully at one time and tried turning the water supply off/on to surge the flow, no difference. As I said above, I don't have faucet aerators to clog and some 3/4 in. copper tubing as well routed to this bathroom.
Please advise ?????
Thanks,
Kenny

Kenny, You ask, "Can tank sediment reach the outlet piping from the hot water tank? If so what can I do to clear it out?"

Yes it can. Minerals build up in the bottom of the tank. If not flushed out they will build up and get in the hot water system and clog the inlet ports of a cartridge or the seats of a faucet. Let me show you how to flush your water heater
