Thanks!
I know this is kind of an old thread, but I wanted to thank everyone that posted here for helping me hopefully fix the problem our toilets were having. My Fianc'e and I closed on a bank owned house, "as is" and unfortunately despite having a home inspection and 2 plumbers check it out, the plumbing issues proved to be bigger than thought. We had figured out before purchase that all the indoor plumbing was above ground, which is pretty unusual here in AZ for a house built after the 40s, so I was unfamiliar with it. Basically what happened is about every pipe outlet in the bathroom walls had been fixed improperly and was slowly leaking underneath the tile floor. We decided to bite the bullet and just update the entire bathrooms, as they were the last rooms in the house to be updated. Obviously, with the above ground plumbing the new toilets had to be rear outlet, which I was totally unfamiliar with and found out the cost a quite a bit extra. My plumber got a pretty good deal on the Crane Economizer, so we went with that.
The toilet in the guest bath was working great, but the one in the master was slowly draining from the bowl and leaking on the floor. My plumber felt it was do to the bowl being unleveled and reset it, but still leak. He said he would try to reset it and if it happened again the bowl must be cracked and he would ship it back to be replaced. We eventually got the guest bath fully functional and with all the other house needs of a new home work on the master was pushed back, so I just cut the water supply and have been waiting to have the plumber back out when we are ready to work on the master.
So come 4th of July we decide to finally have some people over, had a good time but once our guest had left we found water all around the toilet in the guest bath. After checking everything it was obvious the guest toilet was doing the same thing as the master, a result of the extra use on it. We decided to use it sparingly and check into what else may be the problem. I looked up the installation at Crane's site and that is the first time I heard of a "neoprene" seal. I have only set a few toilets in my life and all have been floor outlet with wax rings, which I actually hate wax rings but they work fine for floor outlets. After running searches for neoprene I found this forum with great info! Unfortunately, I was only able to find 1 Zurn Neo-Seal 30 miles away, and no Sioux Chief, but did find some neoprene seal at a plumbing supply store no box or anything for $10.
I set the master toilet last night with the neoprene seal, after cleaning out 2 or 3 wax rings with of crap and after about 10 flushes most loaded no leaking! Hopefully, when I return home today everything will be ok and I'll set the guest toilet!
Sorry, this got so long, but I wanted to say thanks!
Aside from that, the Crane toilets are working well and I love the extra power from the pressure tank.
