Toilet Bowl won't hold water

We got home from our trip to discover that suddenly the rear toilet bowl won't hold water. We need to get that fixed before putting it into storage. Has that happened to any of you? I read one thread that said their bowl needed to be reseated due to being out of alignment. Anything is possible I suppose - especially with the roads we traveled on.
Any other suggestions? I have searched for an hour now and would like to get started! Thanks for any advice you can provide.

It depends on the model you have.

Check the seal around the flush valve/blade. It's either loose or has come off.

I have had the same issue on my older trailer a 2010 Cougar. It turned out that the rubber seal was cut when the toilet bowl was cleaned or the tear was already there and cleaning the bowl jut made it worse. Also sometimes debris will get underneath the rubber seal and the plastic flapper allowing water to drain. So check this first.

I needed to replace the rubber seal and then the bowl would hold water. I purchased a seal on line from a parts dealer for my brand of toilet; replacement was easy .

Should have nothing to do with mounting the toilet. There is a rubber seal on the bottom of the bowl that rubs against the flapper to seal it. Hold the flap open and run a toilet brush around the bottom of the seal. Then boil up some water and pour it into the toilet. Let it sit for awhile. Next after that has cooled a bit, run your fingers around the seal and press it into place against the flapper to re-seat it. If you don't wear gloves for this don't lick your fingers when done...I got this info from the manual for my toilet, well most of it. It has worked every time...

IT has happened to me a few times over they years.
Happens when I use a toilet brush and may unseal the rubber seal.
Like GOTOYS says grab some gloves and put your hand down the hole and run finger around the inside edge while pulling up.
Go all the way around the seal.

If there is nothing physically wrong with the seal, its most likely just junk stuck on the seal. I have had success with vigorous cleaning with a toilet brush. If that , or one of the suggestions above doesn't work, make a cleaning tool by bending 1/4 inch of a coat hanger 90 degrees. Use this to scrape the sealing side of the gasket all the way around

That happened to mine. The flapper had come out of one side of the pedal. All it took was putting it back, and paying for the guy to come out and do it.

I tried the below advise and it worked for me the frist time.

"I heated two cups of generic vinegar in the microwave for about 30-45 seconds. This warm solution is poured into the toilet bowl. The warm vinegar will slowly seep out of the area that is not sealed. Allow the vinegar to soak on the leaking seal for about 30 minutes.
It will dissolve any remaining lime, sediments, tissue, etc., making a good seal. Turn the water on and check to see if the unit now holds water.
You may need to repeat the process several times depending on the amount of sediment around the seal area. Others add a small amount of 303 to lubricate the flush mechanism and the seal. Vaseline is not recommended since it may damage the seal over a period of time."

Good luck

Happened to me. I shut off the water and cleaned both sides of the seal with a soapy rag. No more problem.
