Winnebago Vista toilet clogging

Our 2016 Vista frequently experiences clogging at the bottom of the routing tube beneath the ball valve. Toilet paper seems to collect there and no, we don't flush anything large or copious volumes. A stick pushes the material down and out of the way. Happens on even a very low black water level. Happens to a friends similar 2014 Vista too. Seems like that tube is too long, perhaps extending too close to the tank bottom. Is there a fix out there aside from a stir stick in the bathroom??

Try using more water when you flush or less toilet paper.

Marc, you may want to remove the toilet and check the tube length. It's happened in the past with various brands where the down was too long and was too close to the bottom of the tank. You may need to shorten the tube.

This has been an on again off again problem with ours. Trick seems to mostly be to use a lot more water in the bowl before flushing. This seems to lessen the problem.

Indeed, I have found that works. However, it consumes a limited resource, water. Bottom line, there is a design problem and I would like to fix it. Next time I clear black water and thoroughly clean the tank and toilet, I'm going to look at the down tube to tank bottom clearance. It really should take a minimum of water to clear the tank bowl rather than excessive water to clear the down tube because of buoyant toilet paper.

I'm wondering if anyone has shortened the tube, what is involved and the results.

Thanks.

If you have a pressure regulator on your water input connection, remove it and see if that doesn't help flush things a bit better. I was having the same problem until I removed my regulator.
