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.

### ⭐⭐⭐⭐⭐ Toilet Turmoils.
*by R***S on March 31, 2021*

Well this unit was installed for a family member & they chose to cut cost a little by using least expensive brand & at first I was skeptical but 1st time setting a wall cistern unit so figured it’s their problem later on & my problem installing but actually was really easy & saved YUGE amount of money BC didn’t need to cut concrete in this application to make a 1st level pool bathroom available to all. Instructions are fair at best but always remember U have you-tube available? Some great hints & info there, will purchase this again & bowl as well as wall Unit was quality & substantially sound.
