American Standard 4188A105.020 – Frequently Asked Questions

1) Is the American Standard Cadet PRO 4188A105 a complete toilet or just the tank?
Tank only. The Cadet PRO 4188A105 is the toilet tank with a right-hand trip lever, sized for a 12-inch rough-in, and it ships with the EZ-Install Tools, a metal trip lever and a metal shank fill valve. You still need the matching Cadet PRO bowl, wax ring and closet bolts to complete the fixture.
2) Which side is the flush handle on the Cadet PRO 4188A105 tank?
Right-hand. Standing in front of the toilet, the trip lever sits on the right side of the tank. If the existing toilet has the handle on the left, this tank will not match it, so order the left-hand version of the Cadet PRO tank instead.
3) Will this tank work with a 10-inch or 14-inch rough-in?
No. The Cadet PRO 4188A105 is built for a 12-inch rough-in, meaning 12 inches from the finished wall to the center of the closet flange. Measure that distance before ordering; a 10-inch or 14-inch rough needs the bowl and tank combination made for that dimension.
4) How much water does the Cadet PRO tank use per flush?
1.28 gallons per flush (4.8 liters), which is high-efficiency and meets EPA WaterSense criteria. That is about 20 percent less water than a 1.6 gpf tank, which matters if you're chasing a water conservation rebate or a utility retrofit spec on a multi-family property.
5) Does this Cadet PRO tank use a 2-inch or 3-inch flush valve?
A 3-inch (76 mm) flush valve, paired with the Cadet Flushing System and PowerWash rim that scrubs the bowl on each flush. The larger valve moves water out faster, which is why a 1.28 gpf flush still clears the bowl. Flappers and seals you buy for service need to be the 3-inch size, not the older 2-inch.
6) What finish and part number should I order to match my other Cadet PRO toilets?
It comes in white only, ordered as American Standard part 4188A105.020. If you're standardizing a building on Cadet PRO, that suffix .020 is the white china, and the tank is the trade-exclusive Cadet PRO version with the metal trip lever rather than the plastic handle used on consumer lines.
7) What are the dimensions and shipping weight of the Cadet PRO trip lever tank?
The tank measures 18.938 x 16.125 x 10.375 inches and weighs 31.228 lbs. Useful to know if you're staging a unit turn and need to know how many cartons fit on a cart or in a van.
8) Is the Cadet PRO tank meant for residential or commercial use?
It is classed as a residential, non-luxury fixture in the Cadet family. For apartments, rentals and single-family turns it's a common standardization choice; for high-traffic public restrooms a commercial flushometer-style fixture is the better fit.
9) Does the tank interior resist staining and buildup?
The china carries the EverClean antimicrobial surface, which inhibits the growth of stain and odor causing bacteria, mold and mildew on the surface. It's a finish treatment on the fixture, not a substitute for cleaning.
