1989 Carver 3607 Aft Cabin Head won't flush
We just took ownership of a 1989 Carver 3607 Aft Cabin. Our first boat of this size. She is in great shape and looks to be well maintained except for the aft head.
The electric Raritan doesn't want to flush. When you push the button the pump cycles, "water" is moving in and out at the bottom of the bowl, but water doesn't come from around the top to fill/flush the bowl.
I read through the owners manual, no help there. Is there a switch or a valve or a pump that I am missing?
Someone help the newbie.
