GenieBidet Hybrid LEAK-STOP Chromed Brass 3-Way T Valve Adapter for Bidet With ON/OFF. Simple Hand-Nut Install. Resists Cross-Threading. 7/8 X 7/8 X1/2 Toilet Fill Valve

I purchased this to go with my new Luxe Neo 120 bidet attachment. The Luxe came with both plastic and metal T adapters, but neither had a lever to control the water pressure to the bidet. The beauty of the lever is that it doesn't affect water pressure to the toilet tank, but can decrease pressure to the bidet as well as shut off the water to the bidet if needed. It was easy to install and included a rubber washer (plus an extra one). I applied teflon tape on the metal connections to the supply hose and bidet hose, but did not for the plastic connection to the toilet tank. No leaks! Just make sure you check inside the toilet tank - when tightening the adapter, the float mechanism was pushed up against the tank wall, so the tank wouldn't stop filling. Easy to fix, but something to pay attention to while installing. Very happy with this high-quality adapter!

As intended, dont have leaks anymore

The bidet I bought came with a metal T-adapter but it was cross-threading with the plastic toilet fill valve and it would leak no matter what I do. I installed this and there were no leaks!! I highly recommend this product if you are having the same problem.

I tried some other T-valves, and they didnt work. Most are from China where the thread standards must be slightly different. They dont quite fit the threads of American Toilets, and can actually strip your plastic toilet pipe. This one thread perfect. Also, the others have metal nuts with not much threading. This one has a plastic head, that threads very deep into the toilet. Its a good quality valve, it is super smooth when turning on to off. This was the only one I tried that actually worked. The only drawback, is that the part that screws to the toilet is plastic, which is fine, but has a flat washer. A plastic connector like this should have a cone washer. That is the reason so many reviews mention leaking. I just took a cone washer from an extra toilet water hose I had, and put it on top of the washer already in the valve. Also, make sure the washer in the valve is completely seated before installing.

I purchased my home 7 years ago and since then I have done 95% of my own Plumbing I've replaced hubs for my in-ground sprinkler system. Removed and replace my dishwasher removed and replaced my garbage disposal I have removed and replaced toilets, so I decided to install my own bidet. I figured this was a 30 minute task seeing that I got a simple model with hot water. While looking up and researching the bidets I came across this adapter decided it was not needed. Fast forward 2 weeks later with a constant leak in my master bathroom to the point where I had to shut off the water to the toilet because NOTHING, I did could get rid of a leak from the toilet tank to the first connection of the water line. At my wits end I went back in my Amazon account and found this adapter that I had saved for later and ordered it. I did take heed of the reviews that warned the cone washer is not in this adapter so I supplied my own cone washer and in three and a half minutes my leak issue was GONE, this adapter is super easy to install and it is exactly what is needed to make sure you have a secure leak free installation of your new bidet.
