American Standard 4133A518.222 – Frequently Asked Questions

1) Is this an American Standard tank only, or does a bowl come with it?
Tank only. Model 4133A518 is the vitreous china tank portion with its chrome plated top mounted push button actuator, sold without a bowl. If you are replacing a cracked tank on an existing H2Option two piece, this is the part you need; for a full new install you order the matching 12 inch rough H2Option bowl separately.
2) How much water does the H2Option dual flush actually use per flush?
Two settings: full flush at 1.28 gpf (4.8 Lpf) for solids and partial flush at 0.92 gpf (3.4 Lpf) for liquids, selected with the top mounted push button. It meets EPA WaterSense criteria and is MaP PREMIUM listed. For a property manager swapping out 3.5 gpf legacy toilets, that is a large per-flush reduction across a portfolio.
3) Can I put this dual flush tank on any American Standard bowl?
No. Two piece tanks are matched to a specific bowl by bolt pattern, gasket location and flush valve outlet, and the H2Option system is engineered as a pair to hit its 1.28 and 0.92 gpf ratings. Use the 4133A518 with the H2Option bowl it was designed for. Dropping it on an unrelated bowl risks leaks at the tank-to-bowl gasket and poor bowl evacuation.
4) What colors does the H2Option 4133A518 tank come in, and will it match my existing bowl?
Three colors: White (4133A518.020), Bone (4133A518.021) and Linen (4133A518.222). The suffix after the model number is the color code, so match it to the code on your existing bowl. American Standard White, Bone and Linen are distinct shades, and a Bone tank on a White bowl will read as a mismatch across the room.
5) Does this American Standard tank have an insulated liner to stop sweating?
Yes, it is a lined tank. The internal liner slows condensation on the outside of the china when cold supply water meets humid room air, which matters in basements, un-conditioned restrooms and humid climates where a bare tank drips onto the floor.
6) Is the H2Option dual flush tank suitable for apartments and multi-family units?
It is classified as a residential product and fits well in apartments, condos and single family rentals. The push button actuator is mounted on the tank lid rather than a side lever, so tenants operate it from above. For high-traffic public restrooms in schools or stadiums, a flushometer valve and bowl setup is the usual specification instead of a tank type toilet.
