## Description

1.28/0.8 GPF WH CONC TANK CARRIER

Review: Great product - Works great. Install was a little difficult only because never done before.
Review: reliable duo flush tank carrier that works with Toto CT437FG#01 - I bought this to work with Toto CT437FG#01. They seem to work well together. Toto has its own tank carrier but I trust Geberit more since it's the inventor of wall-mounted toilets and has a lot of experience and installed bases (60 million as I read somewhere). I think Toto tank carrier is cheaper. I like its duo flush and easy access to all the parts (Toto may be similar in this regard.) It's solidly built and well designed. Amazingly it can carry 850 lb and itself weighs around 40lb. Installation seems to be straightforward. It's my plumber's first time installing Geberit (he had done Toto before) and he installed it without any problem. I am happy with it.

## Features

- Concealed tank allows full operation of a toilet without taking up space
- Fully insulated tank - prevents condensation build up
- Built-in dual flush capabilities
- Adjustable toliet seat height - 15" to 19"

## Questions & Answers

**Q: There are two pieces loose in the tank, what are these for?  One is grey in color about 11" by 2" (packaging?)  the other is white cap 7/8 by 1"**
A: It is not clear what the second item is, but the first does sound like a piece of packaging and not a part of the unit.

**Q: Does this come with both the carrier and concealed tank?**
A: Yes.

**Q: Will the opening in the frame to the right of the drain accommodate an electrical outlet for use with the Kohler Veil and bidet seat?**
A: No it will not

**Q: hi i went on the geberit official site, and they just seem to give 3 toto bowls options for the 1,28/0,8 GPF model, how is that possible?**
A: Hello, it could be that specific flush flow rate only offers three bowls, but you have the option to adjust your flow rate, which opens up the possibility for more options of bowl models. All of the flow rates listed on the spec sheet can be achieved with this model, according to Geberit. I would reach out to Geberit directly for technical support, they will be able to walk you through these options and provide guidance with choosing the proper bowl. Hope this helps! Thank you!
