Bubbling when you flush?

Turn off the water, but not the air. Don your rubber gloves. Hold the flush button down to keep the door open. Remove old gasket and install new one. Much easier to do than you probably imagine.

Five minute project.

I have found that a dose of Mr. Clean, Lysol, Pinesol, or other cleaner added to the potty about once a week really cuts down on the swamp gas smell that can come from the hopper in the Microphor.
