TOILET VALVE - Event Date: 27 Mar 2023

The cracked flange issue, I believe, related to the fact that on that particular trailer they use a very tall Dometic toilet that feels a bit like the leaning tower of Pizza when you sit on it.  I was lucky in that when I went to replace the valve, I found that there was also a recall on the toilet and received a new one from Dometic so waited to replace the valve until the new throne arrived.  I had earlier looked at taking the valve out and realized that it was going to be a lot easier to take the toilet off, so I held off until the new toilet arrived.  I believe the flange cracked because the leverage from the tall toilet was just too much for the plastic flange and it cracked at the attachment bolt holes.  The ceramic toilet I mounted solved the leverage problem because it is only about 18" tall, but it is solid as a rock and will not exert any undue force on the flange.

The ceramic toilet is much easier to clean and much more stable.  It was a challenging installation because it needed more rear clearance vis-a-vi the center point of the drain, so I had to cut out part of the wall and inset the toilet.  The advantage to doing that was that I was able to put foam around the part of the toilet at the very back where it went inside the wall space making a very solid installation.  A little bit of seam tape that matched the back wall made the cut out virtually invisible.  i'd post a picture but I don't know how.
