That sounds like the check valve on the rear of the water heater on the hot water discharge is jammed or gunked up with too many calcium deposits. That would be the usual cause as long as this is the case with all the hot water taps. Some are plastic and some are brass and can be cleaned up and reused as long as the spring is intact. Otherwise, they need to be replaced. About $10 and not hard to do most of the time if you are somewhat handy with tools. You just need to turn the water heater off and drain it and get to the hot water outlet on the rear of the unit. I larger Crescent wrency or pipe wrench can take it off. Be careful not to lose the rubber grommet on the pipe fitting. It can drop out sometimes and not be noticed. Hope that gives you some direction here. Please get back to me if you need more as all follow ups are included in our fee. No time limit.
