toilet tank water

I had that same issue with plastic toilets when I allowed the gate to close too softly . When I let it slightly snap closed , it solved the problem allowing it to seal itself to hold water. During winter storage it's usually dry and I've never had any issues.

More than likely, your seal has crud stuck to it. You should keep the slide valves and rubber seals wet. Keep a gallon or two in the tanks so the water will fill around the neck of the outlet. In winter, drain all water and flush all contents .... all,,, then pour some TV antifreeze down. This keeps them wet over the winter.

If they are leaking, try some valve slide lubricant sold at Wall Mart or your local RV dealer. Put some in the toilet or down the sink. Then work the slide valves back and forth.

Other possible cause of this does not work, the casing around the valve could be cracked.

I always keep water/liquid in the toilet bowl to help prevent the seals from drying out - during the winter I use antifreeze.

OK I guess I need to see why they keep leaking and the tank won't hold water. I keep it cleaned no crud on the seal I have used lubricant. I just replaced the seal less than a year ago and the tank is leaking again already. No sure what the casing around the valve is I will google that. Thanks for the help

Don't use anything with a petroleum base. We clean our seal and put olive oil in for any long term non-use.

Tank=bowl?

Gently clean around and under the seal with a toothbrush....not yours..
