The hot water pressure in my house is getting noticeably low since the
beginning of the year. The hot water still runs, but if there're two
faucets running, there's barely enough hot water for both of them.
I've tried draining the hot water tank, but problem still persists.
I'm wondering if it's time to replace the hot water tank (which is 9
years old), or is it due to clogged pipes (I live in San Francisco bay
area which have hard water)?
Also, the shower in the bathroom that is closest to the hot water tank
has no hot water. It seems like the pipe to the shower is clogged, but
the hot water flows fine in the faucet next to the shower.
Any help is greatly appreciated.
