I pulled the plug Sunday night on a 80 hour Kerdi DS flood test. No wicking issues. No leaks.
Test monitored by an evaporation control as well.
When building a Kerdi Shower it is so important that you mark the flood test properly. My tipped coin technique best in class. Make sure you visit my Kerdi Inspection Check List to see how to set up and measure a proper flood test.
There was no drop in water level. No balloons. Just time and proper techniques.
Kerdi shower installs do not wick when properly installed. You find this out in the flood test portion of the build. Tile men building Kerdi Showers and not checking there work are not following building codes. You are not getting any piece of mind that the work was done right.
Insist that this step get done and done for a period of three days.
After a flood test all water should drain away. Here you can see the weep hole locations on this ACO clamping drain.
You only get one chance to waterproof a shower properly - When It's Perfect. It's Good Enough. - JW
