American Standard 4425B104.020 – Frequently Asked Questions

1) Does the American Standard Colony3 4425B104 tank come with a bowl?
No bowl. The 4425B104 is the tank only, complete with a color-matched right-hand trip lever. You order the matching Colony3 bowl separately, so plan on two line items to get a complete toilet.
2) Will this tank work on a standard 12-inch rough-in?
No. This Colony3 tank is built for a 10-inch rough-in, meaning 10 inches from the finished wall to the closet flange center. On a 12-inch rough-in it will sit off the wall and pair to the wrong bowl. For 12-inch openings you need the 12-inch rough Colony3 tank instead.
3) Can I use this as a replacement tank on a cracked Colony toilet?
It works as a replacement only if the existing bowl is a Colony3 bowl set on a 10-inch rough. Tank-to-bowl bolt patterns and the 3-inch flush valve opening are matched within the series, so a tank from one family will not reliably seal on another maker's bowl. Match the bowl model before ordering.
4) Is the Colony3 10-inch rough tank a low-flow toilet tank?
It flushes 1.28 gpf (4.8 Lpf) and is WaterSense certified, which is what most water-conservation ordinances and multi-family retrofit rebate programs call for. A 3-inch flush valve moves that reduced volume fast enough to keep bowl clearance strong.
5) Which side is the flush handle on the American Standard Colony3 rough tank?
Right-hand, and the trip lever comes finished to match the china. If the layout on that stall or bath puts a wall or vanity tight to the right of the tank, check the clearance before you set it, because the lever position is fixed as supplied.
6) Is the Colony3 tank suitable for rental turns and apartment maintenance stock?
That is exactly where it sits. American Standard positions Colony as its builder-grade line, so it is the spec property managers and GCs standardize on for volume work rather than a designer series. Vitreous china wipes clean and the 1.28 gpf flush keeps the unit compliant on water-use retrofits.
7) How much space does this toilet tank take up, and how heavy is it to set?
The Colony3 rough tank measures 21.248 x 16.063 x 10 inches and weighs 29.542 pounds. That weight is normal for vitreous china and is a comfortable one-person lift onto the bowl, but it is also why you want the bowl bolted down and level first.
8) What color is the 4425B104 tank available in?
White only, ordered as part number 4425B104.020. The .020 suffix is American Standard's white code, and the trip lever ships color matched to it.
