Toilet Holding-tank doesn't empty

[400sedanbridge]

Hello there!

I own a 1996 400 sedan bridge and have a problem with the holding-tank of my toilet.

The tank is full and doesn't empty. The macelerator works and the toilet itself does work too. Does anyone have an idea what can cause this problem?

Thanks a lot!

Seacock open?

Are you trying to empty it by pumping it out or running the macerator? If the macerator, check the seacock to make sure it's empty, like the Lord said above. If you're trying to pump it out, I don't have any ideas.

One thought....how long has it been since you pumped it out? Could there be a layer of solids on the bottom of the tank? If it's been a long time since you pumped out, get some enzyme stuff that will dissolve the solids to liquid then try it.

Is your vent open and free? If air can't get in, nothing is going to come out.
