American Standard 4188A104.222 – Frequently Asked Questions
1) Is the American Standard Cadet PRO 4188A104 tank sold with a bowl, or is it tank only?
Tank only. The Cadet PRO 4188A104 is the rough tank by itself, so you need a matching Cadet PRO 12-inch rough bowl to make a complete toilet. It ships as a trade-specific tank for replacement and new-construction work where the bowl is already on site.
2) Does the Cadet PRO rough tank come with the fill valve and flush lever installed?
Yes, the trim is included and it is metal where it counts: a metal trip lever and a fill valve with a metal shank rather than plastic. Those are the two parts that get broken most often on rental and institutional toilets, which is why the PRO version specifies them. You still supply the supply line and the closet bolts/gasket kit that come with the bowl.
3) Can I use this Cadet PRO tank as a replacement for a cracked tank on an existing toilet?
Only if the existing bowl is a Cadet PRO 12-inch rough bowl. Tanks are not interchangeable across models or brands, the bolt spacing and the outlet location differ. Match the bowl family (Cadet) and the rough-in, and match the color suffix so the replacement tank isn't a different shade than the bowl it sits on.
4) How much water does the Cadet PRO 4188A104 tank use per flush?
1.28 gallons per flush (4.8 liters), which is about 20 percent less water than a 1.6 gpf toilet and meets EPA WaterSense criteria. That matters on multi-family and hospitality retrofits where a water-conservation rebate or a local 1.28 gpf mandate is in play.
5) What colors does the Cadet PRO 12-inch rough tank come in?
Three: White (4188A104.020), Bone (4188A104.021), and Linen (4188A104.222). Order the tank in the same color code as the bowl, since the suffix after the part number is the color and mismatched suffixes give you a visible tone difference between tank and bowl.
6) Is the Cadet PRO 4188A104 tank meant for commercial or residential use?
American Standard classifies the Cadet PRO 4188A104 as residential. It shows up constantly in multi-family and light hospitality work because it is a trade-line tank with metal trim, but if you are specifying for a high-use public restroom, a flushometer-valve or commercial-rated fixture is the better call.
7) What is the EverClean surface on the Cadet PRO tank and does it help in high-traffic restrooms?
EverClean is an antimicrobial glaze fired into the china surface that inhibits the growth of stain and odor causing bacteria, mold, and mildew. On the tank it mainly keeps the exterior looking clean longer between housekeeping rounds, which is why property managers spec the PRO line on apartment turnovers.
