THU9090R 6 Inches Hose Extension for TOTO C110/E200/S300/S400 WASHLET, 7/8 Male to 7/8 Female,Stops Leaking of Bidet Sprayer T Adapter Connection to Toilet Tank

As part of installing a fancy toilet seat with built-in bidet, I needed some extra flexible hose between a water supply splitter and the toilet tank. This little part allowed a firm connection to the tank in a cramped area (hoses and parts feed through hidden “cubby holes” at the rear of my toilet bowl).

I was very concerned our skirted toilet would not have the necessary clearance to easily accommodate the T valve needed to install a Brondell bidet seat. In doing some research I came across a short post on Reddit recommending this hose extension. Thank you to the original poster there, it worked perfectly, was easy to connect everything together, no leaks. It even came with a cute little roll of teflon tape.

I actually found this product through a referral from the Toto USA customer support line. We recently purchased a Toto K300 bidet seat to install on our existing Boulevard American Standard toilet. Unfortunately the T-adapter for the Toto bidet would not fit in the tight space to connect to the tank. This hose extender allowed me to attach this hose to the tank and then the T-adapter for the bidet water supply to the end of the extended hose. Perfect!

J'avais besoin de cette pièce pour l'installation d'un siège-bidet. Eh bien j'ai fait une dizaine de quincailleries et nulle part on n'avait cela. Je me suis même fait dire d'aller relire les instructions d'installation à un endroit. Après une semaine de recherches, je suis finalement tombé sur cette rallonge qui correspond exactement à ce que je recherchais. Installation facile et fonctionnement impeccable. Super !

This works, thankfully! I have a terrible situation where I have a Toto C200/SW2044 and a Kohler K-3564/Saile, a skirted toilet. The Kohler had (and called for in the instructions) a 20 inch toilet connector water supply line. Toto claimed universality and ease of use - but obviously failed to research how Kohler doesn’t even bother to have their own standards, lol. Anyhow, in brief, I took a chance on this off brand connector and testing validated that it worked. It was still too short for me to feel comfortable so I bought a second one nad now everything is working. No leaks! Of course, it’s literally been one day since the second one arrived and was installed. I’m happy about this purchase and still POed at Toto for creating the situation - I would have been even more POed if I’d had to pay double!
