Ariel Platinum 'The Hermes' Dual Flush Toilet
We installed this toilet a couple of days ago and we love it. It took me about 3 hours, including removing the old own.
Installing this toilet does take a small amount of mechanical aptitude; about the only thing that looks like a typical U.S. toilet is the wax ring. Be sure to measure carefully. If you don't know how to find the center line of the drain/flange, measure from the edge to a wall, then again 90 degrees to that. Measure the flange diameter, divide by two, and add that to the wall measurements - that's the center of the hole. Now, subtract the dimensions given from the center of the hole to the screw holes from the wall number, and you have your hole positions.
Another suggestion - attach the water line to the back of the tank before setting the toilet in place. If like ours, it's close to the wall, it's awkward to attach then.
One last comment; if you go the bathroom, you may hear water drips. That's because as you add volume to the bowl, it forces water over the air trap and causes a dripping sound; nothing to be concerned about.
