Reckles, No, please don't put a clorox tab in the tank. It will ruin the seals and cause the tank to refill. Sincerely, your American Standard Consumer Connection Team
If you want flush volume ... 1.6 is the max I have found .. watch out for toilets with 1.28 flush ... great of No. 1; but, too little in my experience for No. 2. If you want a nice aethetic ... there will be compromises for flush capability ... Since, flush is really helped by the tank being higher. The old institutional toilets with tanks on the wall at about 7 feet up ... were made to gain the help of gravity. If you have kids ... a shorter bowl might be needed ... as low as 15 to 15.5 inches. If you have older/disabled/elderly persons in the house ... a 16/16.5/17 inch bowl height is needed so that they don't struggle to get off the toilet so much. For a 20 - 30 year lifetime ... consider those that are 'average' of 16.5 inches to top of bowl.
Use only mfrer recommended cleaners ... the vitreous shine is very necessary to help keep the bowl clean. Any marring, scratching, scouring will eventually render the bowl surface rough, and it will make cleaning very frequent and difficult.
If you investigate the H2Option as individual tank and bowl ... which is an expensive route .. you'll discover that the bowl on the An Std Cadet 3 Dual Flush appear to be exactly the same as the H2Option bowl. The tank for the Cadet 3 Dual Flush looks great though doesn't it? ... but, does not have quite the same capability of the H2Option tank. At $188 for the Am Std Cadet 3 ... it is the best value available .. buy it now at that price .. it's not always there. plus the replacement components will be available for years to come. I liked the 15 year old one so much, I added the same toilet for another bathroom recently.
A flexible braided supply line, with Metal connections is best ... it should be long enough to allow flex easily, as the toilet bowl will easily especially when heavy humans sit on the bowl. The new "click" type connector at the tank is highly recommended .. by insurance companies; a recent class action lawsuit against the manufacturer of one made with a plastic tank non-click connector was won by the plaintiffs ... because the plastic connector on its own, would loosen or even fracture over time ... And insurance companies filed suit against the manufacturer.
The wax ring did not come in my box .. nor did a supply line .. .at least the tank components are pre-assembled in the tank. Get a metal braided supply line, at least 1.5 inches too long, and with a 'click' connector to the toilet. The non-click ones, the connector is too soft, will either eventually loosen or crack, causing a flood in your bathroom and the floors below. Insurance companies have a class action suit against one manufacturer of these soft plastic connectors.
If you have your own favorite plumber .. .use him .. but, you'll have to buy the wax ring, supply line or tell him to bring them with him. If you don't have a favorite plumber ... you can ask HD to install .. but, again, include the wax ring and supply line ... and either bring them home too, or make sure they pick them up; having the plumber pick up the toilet and parts .. will cost you for the extra effort.
