American Standard 4188A074.020 – Frequently Asked Questions

1) Will this Cadet PRO tank fit a 10-inch or 14-inch rough-in bowl?
No. The Cadet PRO 4188A074 is built for a 12-inch rough-in, which is the dimension from the finished wall to the closet flange bolts. If your existing bowl sits on a 10-inch or 14-inch rough, this tank will not seat correctly on it. Measure wall to bolt centers before ordering.
2) What trim comes with the 4188A074 tank, and do I need to buy a flush valve or fill valve?
The tank ships with its working trim: a metal trip lever in chrome finish, a metal shank fill valve, and a 3-inch flush valve. You do not need to source those separately. What you do need on top of it is the bowl, the tank-to-bowl bolt and gasket kit, a wax ring, closet bolts, and a supply line.
3) Why does this toilet tank have a locking cover, and is that useful for a commercial restroom?
The tank cover locking device secures the lid so it can't be lifted off casually. Property managers and facility crews use that in public or semi-public restrooms to stop tampering with the flush valve and to keep lids from being dropped and broken. Note that American Standard classes the Cadet PRO tank as a residential product, so for heavy institutional traffic you may want a commercial-rated flushometer setup instead.
4) Is this a 1.6 gpf tank or a 1.28 gpf tank?
It is rated 1.6 gpf / 6.0 Lpf. American Standard also publishes a 1,000 gram MaP score at 1.28 gpf for the Cadet flushing system, meaning the design clears 1,000 grams of waste even at the lower volume, but the tank as sold flushes 1.6 gallons.
5) Does the 3-inch flush valve make a real difference over a standard 2-inch?
Yes, and it is the main reason contractors spec the Cadet PRO tank. A 3-inch flush valve dumps the tank faster than a 2-inch, which is what drives the bowl clearing performance behind the 1,000 gram MaP score. It also means the flapper is a 3-inch part, so keep that in mind when you stock replacement flappers for a building.
6) What does the Aquaguard liner on the Cadet PRO tank actually do?
It is an insulating liner inside the tank that keeps the cold supply water from chilling the china wall, which is what causes sweating and drips onto the floor in humid bathrooms. If you are replacing a tank that has been puddling on a tile floor every summer, that is the feature you are buying.
7) What color does the Cadet PRO 4188A074 tank come in?
White only, under part number 4188A074.020. If you are matching an existing Cadet bowl in a colored finish, this tank will not match it.
