I'm at the stage in my guest bathroom remodel where I was finally able to install my new Toto Drake (CST744, 1.6 GPF) last night. My issue is that I've got a heck of a gap between the tank and wall. I knew that I was going to have a big gap between the wall and tank due to my 14-1/2" offset from drywall. That being said, I thought it would be closer to a 3-5/8" gap (since spec says 1-1/8" gap for 12" R.I.). Right now the gap between top of tank and wall is more like 4-1/2"! Even though it doesn't seem to be leaking, I'm thinking that my Drake may be set a bit forward on the flange.
I think I'll do what Wallijonn suggested in another thread: flip the bowl upside down and check the minimum bolt spacing, and then secure the bolts more towards the back of the closet flange at that width using some extra nuts. The reason I didn't do that initially is because I used a SaniSeal ring and it sort of holds the bolts at a set width. Think the SaniSeal will still work with this method, or do you think I need to go back to tried and true wax?
As for the tank to bowl fit, how much of a gap should there be between the two at the at the front? Mine has a pretty tiny gap there (around 1/8"?), but I'm pretty sure I installed it as per instructions. I tightened the nuts down slightly, checked it with a level, and then continued evenly tightening until the 3 points made contact with the bowl. I'm paranoid about cracking the porcelain, so I just carefully tightened it until there was little to no movement when the tank is pushed.
One thing I'll say is that the flush performance seems pretty impressive! The water doesn't just slowly fill up the bowl during a flush like my 1.6 GPF Kohler... it's a much quicker, more forceful flush on the Drake.
Thanks for the help!
