Manual Flush Toilet

The Jabsco toilet on my 2006 FV270 always bubbles back when I flush it out. Does this happen to anyone else? It is a manual flush toilet. What can I do to prevent this from happening
Thanks in advance

Change your joker (check) valve. It is about $13 on amazon. Its a little black rubber piece. Kind of looks like a funnel. Link below...

When you change it, flush a few gallons of fresh water down the drain. Nothing worse than getting stale urine on you when you replace the valve. Plan on doing that every year or every other year as part of your maintenance.
