Toilets are not the most glamorous thing to talk about in our RV, but I think we have a solution to a water leak problem in our toilet. The toilet bowl simply would not hold water for more than a few minutes so I did some research. After being told everything from replace gaskets to replace toilet, I found a handy inexpensive solution. Put on your rubber gloves and grab an old toothbrush and start scrubbing. I used Thetford’s Aqua Clean and cleaned the gasket around the ball shape closure. Now it closes tight and no more water leak. I was told by a fellow camper that this can be caused by a hard water build up or even tissue that dries on the gasket. No matter what caused it, this product and a little elbow grease solved the drip.
