I recently moved into a 100+ year old house and ever since I moved my hot water pressure just sucks. I tried clearing out the faucets screens and shower head but nothing changed. I don't know what to do and I really don't want to pay for a plumber that "thinks" he might now what's wrong. I tried turning the pressure up but nothing changed. Im about to lose all hope, I don't know what to do at all. If I missed anything that might help let me know.

How old is your water heater?

I would suggest to shut the cold water valve to the heater, drain some water from the heater, disconnect the hot line going out from the heater, remove the nipple check if it is free or you may find it blocked if blocked and it is a galvanize nipple make a trip to a home supply store and ask for a proper nipple this will do it, Thanks.
