    Early on but super impresses so farWe had 3 clogs in 2 weeks with out old toilet!!!After converting our garage into an apartment we had significant clogging issues. Our garage was orinigally the log cabin that the first owners lived in while the main house was built. We tried to save some money so during the renovation we kept the old cast iron sewer lines that were already in the poured concrete floors. Unfortunately, after 60yrs there are two rust spots just past the inlet for our toilet.Needless to say we have made changes. Rapid dissolving toilet paper and this SUPER POWERED toilet should do the trick. Given that our issue is close to the toilet we are hoping that this turbo blast that this toilet provides can speed the TP past the rust spots and on to the smoother pipe. After our initial tests I cannot imagine how this wouldnt be possible. SO MUCH POWER!

    Leaves Nothing to WasteLoud but amazing flush. Equals anything professional. Cost alot of $ but seems worth it.

    Works better than expectedDidn’t know what to expect with the pressure assist but this toilet definitely flushes hard.It does make alot of noise to the point my son said it sounds like the toilet on an airplane, which is actually extremely accurate. Even with the sound I love it for the main floor bathroom. The flush is so strong i doubt even my boys can clog it. It’s also a conversation piece for any guest that has used it!I will admit as much as I am happy with this toilet that I bought a different one for the bedrooms given the sound of the flush. Will buy another for the basement bathroom though.

    Best there is!We’ve used these for over 20 years now. 3 in last home, and 7 in current primary and secondary homes. Yes I bought 10 of them over the years. The flushing performance is truly commercial grade. Yes, definitely louder than standard, but no need to ever own a plunger or worry about overflows. Easy to install except a bit heavy to handle.

    Great Toilet but a little loudI didn’t realize this one had one of those Pressure assist units in it when I bought it. One of the problems with buying online is you don’t always understand what your buying, but I needed this color and it was about $150 cheaper @ Amazon then the local home center stores and I could get it in a few days via Amazon and the local home centers take a week minimum to deliver it, already did that twice with an earlier white one(the first one HD sent me was defective). But this baby showed up in tact and although I was surprised buy the pressure assist unit it works great, best one in the house now. Sounds like a 747 taking off when you flush it but it sure doesn’t look like you can clog this baby, works outstandingly for a 1.4 gpf unit. I wish all of mine worked this well, two of the others are about 18 years old and look exactly the same but they have never worked half this well.

    Fast shipping, great productSo far this toilet works like a champ! Has a nice bladder inside the tank that creates a powerful flush! Happy with my purchase! Also, the seller was great and the toilet arrived 2 days later and was packaged beautifully!! 👏🏼👏🏼

  9. Kaisa Nagel

    Flushes like a dream!Arrived early and was well packaged to help avoid damage during transit. Installation was easy and flushes like a dream! No complaints about the noise so far. Very happy with this toilet.
