Question

Hot water pressure is bad throughout the house not just at washer and shower, but cold water is fine everywher

Answer 1

if you have 30+ yr old house, and you have steel pipes, they will rust up and have to be replaced, if not, check valve on top of waterheater and make sure its full open, also (what I would do) ischeck for t&p valve leaking severely or look at meter (make sure no one is using water inside) and see if meter is turning ( possibly underground leak)

Answer 2

Run water from the faucet at the bottom, and see if flow there is adequate.  If so the problem is in cold water line or inlet, the heater or in the hot water pipes themselves.

You could temporarily disconnect the hot water pipe from the heater and see if flow there is adequate.  This might necessitate putting a faucet on the hot water discharge pipe.

Answer 3

Either the hot water pipes need to be replaced or the water heater needs to be replaced.

Answer 4

You may have some rust in your pipes or your heater that is slowing down the water. Best thing to do is call a pro and get it cleaned.

Answer 5

2) you have an obstruction near or at the water heater outlet side such as corrosion at the union.
