Review: very good value - Most importers seem to be using this WDI brand concealed tank system so parts should be easy to get. WDI appears to be the largest manufacturer of toilet components in China and their quality seems to be quite good. I've used their flush valves and float valves as replacements in other toilets and had zero issues. Everything can be accessed through the actuator plate opening. The float valve and flush valve snap in place and are easy to remove and replace. Overall quality seems to be quite good. Frame is sturdy with clean welds. Instructions are a bit fuzzy. Watch some YouTube videos about similar units before attempting an install. Use the version for 2x6 walls if you can. The 2x4 wall version is more money and the drain is more of a pain to install since it barely fits inside the wall. Really can't be beat at the price. Very satisfied.
Review: Good wall-hung toilet carrier - Good wall-hung toilet carrier for residential use. Installed six months ago and it is working fine. Adjustments to flushing mechanism are possible, but no instructions are provided. Used instructions from a similar toilet to make adjustments. Drain connector requires 4" flexible coupling with 2x steel tightening straps (separate purchase, see Fernco). Standard PVC fittings will not work.

### ⭐⭐⭐⭐⭐ Update
*by A***R on June 22, 2021*

Missing parts. Loose or broken parts in tank. If they make this right I’ll make an update It wasn’t missing any parts. A part came loose and probably happens from time to time that a plumber on his first day could figure out. This is a great toilet system, the best I’ve ever used
