In response to Re: Low/erratic hot water pressure
the same problem occurred with the hot water before the washer was changed (after the pressure regulator was replaced there were three days time before the plumber came back and changed the washer.)

: There should not have been a washer in the hot water tank supply valve. If there was, then it may not have been installed properly. If it was a gate valve, then the wrong piece could have been installed and it came loose and is blocking the water supply to the heater.

: : I have a split entry house with two up and one down. I began to have trouble with the water pressure. At first, the pressure had a large increase. After time, the hot and cold water pressure decreased to a trickle. We had the pressure regulator changed and also a washer in the shut off valve on the cold water pipe leading to the hot water tank. The pressure seemed normal for a brief time (until the plumber left). Then, the cold water pressure remained, but the hot water was/is erratic. The only way to get the pressure back is to turn on the cold water first, then the hot water at the laundry tubs in the basement (a few feet away from the hot water heater), then, the pipes bang a little and we get the pressure back in the whole house. (The downstairs bathroom pressure is also affected until we do this)
