American Standard 4133A115.020 – Frequently Asked Questions

1) Is the American Standard 4133A115 tank a right-hand or left-hand trip lever?
The trip lever sits on the right-hand side of the tank, and it's chrome. If the bowl you're pairing it with was set up for a left-hand lever, this is the wrong tank half.
2) What flush volume does this American Standard H2Optimum tank use?
It's a 1.1 gpf / 4.2 Lpf tank, so it's a high efficiency flush rather than the older 1.6 gallon standard. Worth knowing before you pair it with a bowl that expects a larger flush volume.
3) Which toilet does this 4133A115 tank belong to?
It's the tank half of the American Standard H2Optimum Siphonic Right Height toilet, in the H2Optimum / other dual flush family. It's sold as a replacement tank, not a complete toilet, so you need the matching bowl.
4) Will this tank work with a 10-inch or 14-inch rough-in?
No. This is a 12-inch rough tank, meaning the bowl it mounts to is set for 12 inches from the finished wall to the closet bolt centerline. A 10-inch or 14-inch rough-in opening needs a bowl and tank matched to that dimension.
5) How much space do I need for the 4133A115 tank, and how heavy is it?
Figure on 16.125 x 9.375 x 17.563 inches and about 33.23 pounds. That weight is a one-person lift but awkward on a ladder or in a tight water closet, so plan the approach if you're swapping one in an occupied unit.
6) Is this American Standard tank rated for commercial restrooms?
It's classed as a residential product. For a high-traffic commercial restroom, a flushometer bowl or a commercial-rated tank type toilet is the better call.
7) Do I need to buy bolt caps separately for this American Standard tank?
No, two color-matched bolt caps come with the tank. The tank ships in white, so the caps match a white bowl.
8) What color does the H2Optimum tank come in?
White only, ordered as part number 4133A115.020. If your other fixtures are bone or linen, this won't match.
