Clean the seal. Put on a pair of rubber gloves and run your finger around the seal. Careful not to let the ball snap shut on your finger! OUCH.

Easy 1st - Add some cooking oil to a dry bowl. Let it sit over night and fill bowl 1/2 way if water. Seal may swell enough to seal.
If that doesn't work, Go to Lowes/Hope Depo and get some silicone plumbers lube and when you have your gloves on to clean the seal, lube the seal with the silicone lube.

I just successfully affected an easy remedy on my Dometic #3 toilet. The posts above sound good, but here's what I did. Turn off the water supply and step on the pedal to open the toilet. Reach under the black seal and pull gently up all around the seal's circumference - do it all the way around several times. Release the pedal and then pour a quart of hot water into the bowl and let it sit until cool. It worked very well for me, after suffering with a leaking seal and the accompanying odors for months.
A proper quick, brave, steady, ready gentleman!

I did all of the above. I ended up buying a repair kit from my local RV store. Now I have no problems. Repairs took about one hour to complete. Comes with complete instruction on repair.
