We bought our camper used. It was fairly new had only been used a few times and then traded in to the dealer. When we used the toilet for the first time, we noticed a Puddle of water around it. We clean that up and then the second time we used it. It was the same thing we thought perhaps the toilet ring had come unsealed. This kit has everything you need to replace the ring on your toilet easily. We actually ended up purchasing a new toilet this one ceramic and didn’t need to use this kit. But I am keeping it around because it is A great repair kit in case the pieces that came with our new toilet fail. Great value because you do not need to buy each part Separately.
