We had 3 Universal Rundle toilets in our house and all of them would clog up and require a plunger to clear. I have to admit my solids can be a bit awesome at times so I needed a powerful toilet system. We purchased a TOTO UltraMax with GMax and CEFIONTECT finish. I replaced one of the toliets about 2 months ago and the UltraMax has been a great improvement. I have only managed to clog it twice before I learned how to flush this toilet. It has a unique flushing action and the flushing handle works different than any toilet I have ever seen. Since I learned the secret of flushing this toilet it hasn't clogged again. It appears that the UltraMax will solve my continual plunging problems.
