Kohler K-4645 Reviews

Rated 5 out of 5 by from Flushed with success This toilet is awesome! It really flushes "everything" away with the strength of a hurricane west wind! No kidding, I used to always plug up the toilet but have only done it once with this one. If you buy this you can almost throw away your plunger! Oh yeah!!!

Rated 5 out of 5 by from Better with Age My landlord bought two of these toilets two years ago and they were great. Now I have my own house, I bought three of them, and they work better now than 2 years ago - better as in just as effective but quieter. The tank uses water pressure, not gravity to flush. After flushing, water pressure fills up a sealed bladder, compressing the air in the bladder until the air pressure matches the water pressure. When you flush, the pressurized water shoots out the bottom, sucking the bowl contents down the drain using eduction. If a bowling ball could fit down the drain, this toilet would flush it. Pros: Will flush anything you put in the bowl. Cons: Since it is a mechanical device, it vibrates and the tank bolt nuts will work loose. Use blue Lok-tite to ensure the nuts stay tights, otherwise you will blow tank water out the side of the toilet every time you flush.

Rated 4 out of 5 by from Very good toilet Tank along w/bowl works great - replaced an old low toilet that I was unable to get up off of w/o leaning across to reach shower handrail on wall opposite from toilet. Now able to get up easily. Excellent flushing solids and liquids where old toilet took several flushings. Tank back is several inches away from wall & shakes when toilet is flushed, but I believe that is because of where the floor opening to the sewer is & the bowl has to be over that. I live in an independent senior living facility in a building built in the 1970's, so that can't be changed.
