American Standard 4133A204.020 – Frequently Asked Questions

1) Does the American Standard H2Option 4133A204 tank come with a bowl?
No. The 4133A204 is a tank only, shipped less bowl and less seat. You order the matching H2Option dual flush bowl separately, plus a seat. The tank does arrive with a chrome trip lever mounted on the left hand side, so no trim purchase is needed for that.
2) How much water does the H2Option dual flush use per flush?
Two volumes: a full flush at 1.28 gpf (4.8 Lpf) for solids and a reduced flush at 0.92 gpf (3.5 Lpf) for liquids. It is WaterSense listed and carries a MaP PREMIUM rating, so it meets the criteria utilities usually require for water conservation rebate programs.
3) Is the trip lever on the left or right, and can I get it in another finish?
Left hand trip lever, supplied in chrome. That is how the tank ships, so if your bathroom layout or adjacent wall makes a right hand lever necessary, this is not the tank for that opening.
4) What is the exact part number for the white H2Option ADA dual flush 12 inch rough tank?
American Standard part number 4133A204.020, the .020 suffix being the white china finish. It is the only finish this tank is built in.
5) Will this toilet tank hold up in an apartment or rental unit?
American Standard classes the H2Option tank as a residential product. The tank interior carries the EverClean antimicrobial surface, which inhibits the growth of stain and odor causing bacteria and mold on the china. For property managers standardizing across units, note it only comes in white, so it matches existing white china fixtures.
6) What are the dimensions and weight of the American Standard 4133A204 tank for shipping and handling?
The tank measures 16.125 x 9.375 x 17.563 inches and weighs 33.23 pounds. That is a one-person carry but heavy enough that a second set of hands helps when setting it on the bowl and seating the tank-to-bowl gasket without cracking the china.
