I'm having a problem with my Jabsco marine head.
The unit is relatively new (used one season).
The issues are:
I have taken the pump apart top to bottom: checked the joker valve and the flapper valves at the top and didn't see any obvious issues.
I checked the vent and found that a spider had nested in there. I removed the vent through-hull and the vent tube right down to the tank. The tank seems to be venting well now, but the pressure issue still persists.
The drain hose is free of obstruction.
I'm convinced that the problem lies in a faulty pump assembly, but am open to any other suggestions as to what might be the problem.
A replacement pump kit is almost as expensive as a new unit ($159.00 at my marina). I'm inclined to replace the whole toilet.
If I were to replace the existing toilet any suggestions for a replacement brand at a comparable price?
As always: time is of the essence.
Thanks in advance.

The issues are:
- even when the lever is on the 'dry bowl' side and the handle is twisted into the 'locked' position, water slowly seeps in from the intake side, filling (and overflowing) the bowl.
- on the down-ward (flush) plunge there is a lot of resistance. This feels like pressure, not friction. I noticed this when I first installed the head but found that by pushing the further over to the 'dry' side the pressure was aleviated. I figured it was a slight misallignment of the flapper valve and could live with it. This year the issue is worse and no amount of adjusting the lever resolves the issue.
