Toilet gasket not holding water. Need a temporary fix.

Sorry to be MIA after posting original. Been on the road trying to make up for lost time.(Another issue. Had to have engine part overnight shipped to Midland, TX).

Talked to Thedford and they recommended only silicone lubricant, which didn't help. Got part being shipped, along with a malfunctioning flush valve replacement. Technician said to stop using Softscrub.

Only two more nights. Pouring hot water into the bowl seems to swell the rubber enough to seal pretty well. Will do an overhall when I get home.
