TOTO THU855 Auto-Flush Kit for Washlet S7A/S7 - Dual Flush Toilets Only

Fair price for genuine Toto washlet that was shipped promptly

Searched Amazon for the TOTO part I needed to convert TOTO toilet to auto flush. Everything went well, but the part received was the wrong part, due to some assumptions on my part as well as lack of information on Amazon website. Thank goodness for Amazon return policy!!
Continued search on web after clarifying with TOTO which part I actually needed. Found Premier Bidet website, and liked the details they provided, as well as favorable reviews. Part was in stock, ordered part, and received part in timely manner. NO problems with entire process. HIGHLY recommend to others seeking assistance in purchasing products of this nature.

Recently purchased a Toto S7A and the auto flush from premier toilets. After visiting Japan getting these in our new home was our top priority. It’s been spectacular so far - no flaws with the purchase and everything works without a hitch. There was a hiccup with the valve flap being chipped but Toto was quick to respond and replace that little part ASAP. The auto flush was the easiest thing ever to install - I’ve never done anything plumbing related in my life but found it so easy to do. The product itself shipped fast and the purchase was the most competitive in terms of pricing. Will definitely be looking to premier bidets for all our future needs!

Install was super easy. There are instructional videos on YouTube. The package includes the additional buttons to add to your S7A remote. The autoflush and remote flush is a very nice upgrade that I appreciate even more that I thought I would. This part is of very high quality.

I do not believe the S7 is as good as the S550e we have enjoyed over the past few years.
In a word, We are disappointed with the S7

I was grateful to Premier Bidets for getting me the new S7A bidet and the updated Flush Unit. I'm just in the process of installing them -- and I've had a hard time to find installation instructions. All the ones that pretend to be for the THU855 are really for the last generation, which are very different. I finally found one Toto video on YouTube, which seems to do the trick. But Toto needs to update what they include with the new products. Hope all this technology fits together well. To be continued . . . .

The auto flush unit is compatible with my toilet seat, it’s just not compatible with my toilet flush system. And there are no directions that advise what kind of compatible flush system would work with it. So, I can only caution a buyer on this factor.
