[C320-list] Hot Water Pressure at a trickle

[BA1978 at comcast.net]

Hi Rich!

New member here... So, given that you can't fully drain the hot water tank with the drain being 3-4 inches above the bottom of the tank, do you not add antifreeze to the tank and just figure that the freezing of the water in the tank will expand into the empty portion of the tank and not cause damage to the tank?  Seems like there must be a way to more thoroughly drain that tank.

Do you see the same effect at the head sink and galley?  If so it points to a restriction in the plumbing going to and from the hot water tank, or within the tank itself.  When I winterize the fresh water system I bypass the hot water tank and drain it - if this is how you winterize it may help isolate where the restriction is happening.

All of the plumbing connections are located under the sinks, behind the drawer assembly (which is held in place with 6 screws.  This is an area of the boat worth becoming familiar with.  Lift the stairs up and hook them to the companionway slide, then remove all three drawers (there is a toggle stop on the back of each drawer which prevents them from coming out until you turn the toggle to the horizontal position).  Once the three drawers are removed, remove the 6 screws holding the drawer assembly in place and slide it out (you could keep the drawers in while doing this, but the assembly is heavier and harder to maneuver this way).  Once this is out you can see the plumbing lines.

Others will likely chime in with suggestions as well.

Hoping you find it is something simple.
