I had a new water heater installed about a year ago. I have noticed
that over the course of the year the pressure has gotten worse to the
point that in the bathroom furthest from the hot water heater there is
barely any pressure coming from hot water in bathtub. When they
installed the new water heater they added a valve on the inlet side of
the water heater. Is it possible that this valve is either corroded
with sediment or bad all together. Please any help would be appreciated.


If the valve is blocked it would effect all your fixtures not just one.
So are all the fixtures losing pressure ? ( your actually loosing volume)
Did they install new dielectric nipples? they look like a 3/4" galvanized
nipple screwed directly into the water heater. If so some have a built in
check valve, This could be causing a problem could be stuck. If it is just
the bathroom it could be sediment is stuck in the fixture. Allot of times
when you work on a plumbing system crap gets in the lines.
