The trailer is in winter storage and suddenly for some unknown reason it quit holding antifreeze in the bowl. I feel replacing the entire toilet will be quicker and easier than trying to replace the flapper and gaskets on the old one.
This issue is very common issue with all Rv toilets, it comes from one of two issues;
1) dirt that has become stuck to the ball gasket, this is easy to clean and should be cleaned on a somewhat regular basis to stop this condition
2) The ball gasket on the new models pulls out "without removing the toilet" they where made for just this kind of issue if the gasket become ripped for some reason. It is a one minute fix at most.
If you are like some who have added some type of grease to the ball gasket the water makes the grease ball up and stop the gasket from making a full seal, all that needs to be done with this issue is again clean the gasket.
There are many videos around the internet and utube that will show you how-to clean this ball gasket, so do nor waste your money on a new toilet.
The only reason to replace the toilet is to upgrade to the 320, which is a better model but is also more expensive.
Hope this helps you out and Happy camping and Merry Christmas
