I wouldn't do that. The tank and bowl are designed to work together and you really wouldn't gain much if any. Technically if the bolt hole pattern between the tank and bowl and the flapper hole matched EXACTLY you could. But if you are doing this to save water, you are already at .8 gallons per flush (GPF) which is near the liquids only flush volume. If you would want higher than .8 GPF for solids, even double flushing is 1.6 GPR vs. 1.3 GPF for other high efficiency toilets. It's a fantastic toilet designed for .8 GPF.
We don't have much trouble with that. But if you hold flusher down longer will dump more water out of tank in toilet to help flush things down. Hope this helps.
I bought one and simlpy installed it. I used high quality installation stuff (water line and seal). I've been using it for several months and I love this toilet! I will buy these from now on when I need to replace a toilet in my house. I still have two to go, so when they crack, the Niagra Stealth will replace them. Some people prefer to call their plummer to install them, which might be a really good idea if you want to make sure it is installed correctly. I have a backgound in Facilities Maintenance, so I know how to do it myself.
Most plumbers will charge in the range of $200. Some more, some less.
Funny..!!! I have had very little of that.
Everything but a good seal and water line.
Back to answer my own question: I installed a Niagara Stealth yesterday. The only sweat I've seen was after the tank was initially filled, which dried up in a few hours and has since stayed away, even after the evening showers. The Stealth uses only about a fifth of the water in the tank to flush so it isn't being subjected to a massive drop in temperature after every use.
My local water districts in Missouri and in Nevada did not offer a rebate. You will have to call Sequel Creek water district and the municipal government to see if either of them provides a rebate.
Yes. Just like a nomal one
