Dometic 320 toilet , bought new and installed a little over a year ago.  Worked fine on three trips last year,  but now the bowl won't hold water . Cleaned flush ball and seal , replaced seal , tried petroleum jelly . Still leaks . New seal was not from Dometic. 
Any advice appreciated! 
Thanks, 
Chris
I too had this problem. I paid 9.95 for the generic seal and ball and it has leak down l. Paid an additional 25.00 for the  oem real deal and my problem was solved. We full time, and have discovered that even  the life span on the oem is less than 2 years.
