My advice is DO NOT BUY THIS TOILET! Here's why:
In 2009 I remodeled/updated a couple of bathrooms in my home and decided to replace all of the toilets (so they would match). The original toilets that were installed in 1994 were Briggs, and they never flushed well. This time I wanted toilets that would not choke on a piece of toilet paper, so fell for Champion's claim that the Champion 4 could flush a bucket of golf balls. I bought three Champion 4 toilets model #4266 and installed them. So far, I haven't noticed any problems with the the toilets that were installed in the master bathroom or the downstairs bathroom, BUT the toilet installed in the MAIN upstairs bathroom has leaked almost constantly from the day it was installed. The water in the tank leaks out to a point near the top of the gray/green tower. So, I assume the water is slowly leaking at the seal or at the chain attachment at the top of the flush tower...
I did register the toilets with American Standard after purchasing them, so when I noticed the toilet leaking I called customer service and they sent me out a new seal. I replaced the seal and the toilet kept losing water. It's been so long ago that I don't remember all of the details, but at one point it seemed that water was leaking out of the black plug at the top of the tower where the chain attaches. I called customer service again, and they didn't have a solution for that. So I installed a washer around the plug and thought that helped for a while, but it has basically leaked from the day it was installed.
Since there are 2 other toilets here, I have resorted to turning the water off and on at the shut off valve to keep from wasting so much water (water/sewer costs are very high in my city!). About a month ago I called AS customer service again and told them it was STILL leaking. They sent out a new flush tower which I had the pleasure of installing about a week ago. Besides the constant leaking, the toilet is designed with a porcelain lip that hangs down along the sides of the base which makes it very difficult to access the nuts on the tank bolts. You can't see or find the bolts without lying down on your back on the floor and becoming some sort of contortionist. I have to thank the MORON for his lack of intelligence in coming up with this terrible design (It must have taken all of 2 brain cells....).
Anyhow, I was hopeful that this would fix the problem but I wanted to test it out. So after installing it, I allowed the tank to fill and then I turned off the water valve so it couldn't refill. Over night, the water level dropped to the top of the tower again; at the level of the gasket. How disappointing! Once again, I have to wonder what MORON designed this horrible toilet, and what MORON at American Standard approved the design? After reading about so many other people who have had the same problems, it seems criminal for AS to be able to continue selling this junk!
So yesterday I called customer service AGAIN to complain about the continual leaking. This time I was told that they would send me a new tank with new innards already installed. BUT, before they would send me the new tank, I would have to send them a copy of my original receipt, a photo of the toilet and a photo of the inside of the tank! So I spent approximately 14 hours digging through files yesterday with no luck. Then this morning I finally found one and emailed the "PROOF" of purchase and leaking to customer service so that I can eventually get a replacement tank. I can't help but wonder if they think I STOLE this piece of junk and WHY they were previously willing to send me the gaskets and the flush tower without the receipt and photos, but now they want proof of the purchase and photos of their stupid toilet? It seems to me that they were hoping I didn't have the receipt so that they could deny coverage under the warranty. I guess they don't know who they are dealing with...(someone who is obsessive about keeping receipts & booklets for just about everything purchased, and especially things that have a warranty. He, he, he).
When I spoke with the man at customer service yesterday, I asked him; "What if the toilet continues to leak after I install the new tank with new innards"? He said that the odds of me receiving another bad tank/innards would be "astronomically" rare and that if it leaks, the problem would have to be with the installation!!?? What a bunch of BS! I also asked him if the leaking was a major problem with this toilet. He said they have had problems with some of the older seals, but that the new seals and/or tower should have fixed the problem. Huh. I'm thinking that response is the company line...
Well, I tell you what, I have absolutely NO CONFIDENCE that a new tank with new innards will stop the leaking. I am convinced (after reading other posts here) that the toilet design is DEFECTIVE and that AS just won't fess up to the problem. I think that while I am waiting for the new tank to arrive, I will begin shopping for a Toto toilet. Maybe I can put this toilet on Craigslist and get a few bucks off this one, but I hate to pass the problem on to someone else. (Well, maybe it wouldn't be a big deal for someone who had a flat water/sewer rate). It sure seems to me that there should be a CLASS ACTION SUIT against American Standard for their defective Champion 4 toilet!
I'll try to give an update after I get the new tank installed and have had a chance to test it for leaks.
