I have galvanized steel pipes, about 47 years old, and the hot water pressure is very low, even on the short runs. I can see where some leaks have been repaired in the past and there are some rust spots in other areas. I've been advised to change the horizontal supply lines first because they are easy to access, and then the risers if the problem still persists (idea is not to cut open too many walls unnecessarily).
Questions are:
1) Is this sound advice
2) Could there be other reasons for the low pressure (the heat traps have already been removed from the water heater and the fittings cleaned)
3) Is there a way to clean out galvanized steel pipes either with pressure, a chemical or mechanically to avoid changing the pipes?
Thanks in advance
