hard to pump

[dave]

When pumping in raw water to flush the bowl the pump appears to be pressurized and hard to pump,very little water is taken in to flush.Whats up?

 

[Bob Lufkin]

I have the same thing, I have a very tight kink in the hose which I need to fix.Dumb question, but is the sea water valve open?

 

[dave]

yes the valves are open,could it be the holding tank needs a pumpout?

 

[Steve Dion]

Vent Clear?

Dave:What type of head do you have?Have you checked the vent to see if it is clear?

First questions, then answers

Make/model of the toilet?Do you only feel the backpressure when the valve is set to "Wet" or also on dry?

 

[DAVE]

IT IS A PAR MODEL??CHEAPIT PREASURIZES WHEN VALVE IS IN WET POSITION AND APPEARS TO EVACUATE OK IN THE DRY SIDEI,M JUST BUYING THE BOAT AND HAPPENED TO NOTICE IT.

Aha...

The wet/dry valve has failed...it's a VERY common problem with Jabsco toilets. The valve hangs, partially closing off the intake, preventing the toilet from bringing in any water and creating back-pressure. The cure: replace the wet/dry valve. While you have it apart is a good time to lubricate the toilet. Buy a tube of Super-Lube (same thick teflon grease that was in it when it left the factory). Put a healthy squirt in the pump, pump a few times to spread it all over the inside of the cylinder. Not only will your toilet need no further lubrication for a full season, but by doing it now, the grease protects the rubber parts in the toilet from drying out over the winter. You'll be good to go next spring.
