Well, the Toilet Seal Conditioner didn't stop the leak so I took the toilet out and took out the seal. This is the seal that keeps the water in the bowl. The toilet doesn't come apart so you have to reach into the bottom where it attaches to the black tank, YUK!!! The seal seemed to have a lot of mineral deposits on it so I scraped them off, reinstalled the seal and it held water. It has held the water now for about 4 hours. If the water is still in the bowl in the morning, I will declare victory and reinstall the toilet.
There was a lot of other "stuff" in the toilet so I used the garden hose and gave it a through hosing to clean it out.
Oh yeah, I sanitized the fresh water tank and hoses and ran the chlorinated water thru the faucets. No leaks in the plumbing I did a while ago when I installed a new kitchen faucet.
