I have real low hot water pressure. My cold water pressure is fine, what could be the problem? The hot water is hot, it is just comming out real slow.
You most likely have a piese of rust from the hot water heater stuck in the hot water valve or the water line to it. Turn off the water pump and relieve the presure. Remove the valve and check for damage to the valve or debris blocking it. In a house you would have an angle stop to turn off water to that valve. you don't have that luxury. I would flip the pump on and off to purge the water line. Put a rag or something over the opening so you don't shoot water up on the liner. Also, check for a kinked water line.
