    Need this Adapter
  

*by A***R on Reviewed in the United States 🇺🇸 on October 23, 2017*

The reviews are mixed for some reason, I needed this part to connect to American toilet ..  I bought the Toto Washlet 100 and it came with a T which connects to the shutoff valve and to the bottom off the toilet tank. I spent hours trying to fix the leak which comes from the connection on the bottom of the toilet.  The even though it’s the same size connection, the thread pattern is different.  I think the Toto Washlet T has metric threads.  This 6 “ adapter had the correct thread pattern on each end to connect the T to the toilet and shutoff valve.  With that, the water hookup took 5 min.  If you are buying the Toto Washlet 100, you will need this part for American toilet.  Yes...it’s massively overpriced......but they have you by the nads on this adapter

    Essential if you don't have a lot of room under your toilet tank
  

*by P***H on Reviewed in the United States 🇺🇸 on October 12, 2017*

Expensive, but absolutely essential little extender.  Some reviews said this does not work with the e350 but I don't understand those reviews.  I found this extension hose to be absolutely necessary to install my e350.The e350 comes with a very large T splitter.  The size of the splitter makes it cumbersome to install correctly to the bottom of your toilet tank without leaking.  This extension hose installs to the bottom of the tank and gives your the room you need to connect it to the T splitter.  It's also a non-standard size so you can't find this hose in common hardware stores or the local lowes.  This is not a standard toilet waters supply hose. The connection threads are a different size from the common toilet supply lines.

    Needed for skirted toilets
  

*by J***N on Reviewed in the United States 🇺🇸 on August 3, 2015*

Exactly what I needed for my Kohler skirted toilet. I practically gave up on being able to install the Toto Washlet seat after having spent a couple of hours taking apart my toilet to separate the tank from the seat and found no clearance for the t-adapter. I was about to return the Washlet seat when I found this related accessory product. I can't believe I spent hours looking for something like this at Home Depot, Lowe's, Ace Hardware and all this time Toto had it available on Amazon - they should have mention this in the washlet installation instructions. I took away one star because of this and the outrageous price - should be no more than $10-15 as compared to similar hose adapters.
