Review on 🚽 Mission Automotive Dometic-Compatible Flush Ball Seal Kit for 300/310/320 RV Toilets - Replaces Parts Number 385311658 - High-Quality Replacement Gasket by Rob Allen

Worked on my Dometic. It fit perfectly and did its job. FOR ALL THESE PEOPLE WHO WON'T SAY: Either they don't know the model of their toilet (look at your toilet and google images for "Dometic 310" or 320 toilet) AND/OR your ball valve has slipped and you have to return it to its place. Turn off the water --> Open the ball valve --> Use a long tool with a hook on the end ie crowbar etc (or your hand if your hand is small enough, I don't have one) ---> Lever up the swivel arm --> pull carefully, BUT with some force. You MAY hear or feel a click as the ball valve re-engages. If that doesn't work, you have to turn off the toilet and turn it around and you'll see the connection point clearly. It is very light compared to a normal toilet. Much luck!
