Hi,

I have very low hot water pressure in my shower and tub. The pressure in the cold water seems to be fine. It's a double valve system. Is this an easy fix or do I need a plumber?

Did this just happen? What size pipes to feed the tub? Also is it steel pipe/copper/CPVC ?How are the other facuets bath sink(s) and kitchen hot lines.and are they slow also? Tub could be stem and valve seat problem with opening all the way. If the same now its to hot water heater nipples.
Need more info

It's copper piping but I'm not sure what the size is. All the other faucets in the house are fine. Another thing I noticed... if I turn the hot water valve just a little or a lot, it makes no difference in pressure or temperature. The cold water valve seems to be fine.

Brand and model of faucet would help. You say other fixtures are fine on hot. Is there any pressure difference from hot to cold at other fixtures. If even a little diffence, then pleae let me know.

I just moved into an 80 year old house so not completely sure on the brand and model. On the valves, it says "Central". From what I can tell, there is no discernible difference in pressure differences in any other faucets.
