Review: Easy install, small package, absolutely no leaks! - So I wanted to connect a sprayer to the toilet bowl, unfortunately the typical connection wasn’t possible. Most sprayers or bidets connect to the base of the toilet tank using the 7/8” toilet tank pump. My toilet at my apt is one of these where most of the tank plumbing is hidden and inaccessible because I have some “fancy toilet” I guess. After so much borrowing and multiple trips to the hardware store I had purchased several pieces needed to connect a simple sprayer. In the pic I posted with this review you can see all the other parts needed in order to connect a sprayer or bidet. In total I had spend around $50 in parts. I’m the other hand this small affordable valve I finally found on desertcart was able to achieve what I needed; to connect a sprayer and a regulator valve to the toilet plumbing. It took me less than 5 minutes to install this valve. It works perfectly and easy access to it. I can control the flow and turn it off when not in use of while not home. It is sturdy, well built, and seems durable. It also came with all the seals needed to prevent leaks. You will not find this valve at The Home Depot, Lowe’s, or Ace Hardware. I went to all those hardware stores and I wasn’t not able to find it or anything remotely similar. The only option they have is to spend lots of money and to purchase several parts and if doing so, you have much higher chances of having a leak. I definitely recommend this valve. Completely worth it!
Review: Helpful for skirted toilets - Seems to work so far, does what it says on the page and is worth the extra money for those toilets where the tank fill is fairly inaccessible. Some other comments noted that the 1/2" adapter is a bit of a pain since tightening the hose on likes to unscrew the adapter. It's an issue for sure, but the adapter is kind of forced that way to work. It's fairly painless to put the adapter in, get it nice and tight, then use a second adjustable wrench or similar to hold while tightening the bidet hose on. Getting one without an adapter is an option, but the flexibility is nice. All in all, just what I needed and annoying that the actual bidets don't come with or give an option to get. It's not exactly an uncommon plumbing layout these days, especially with the pex waterlines pretty standard.

### ⭐⭐⭐⭐⭐ Fits Toto S5 washlet
*by A***N on November 14, 2025*

Adapter does fit Toto perfectly. Used Teflon tape since it is metal to plastic but no leaks and threaded easily. Obviously, be careful not to cross thread. Part is machined well and high quality. I ended up using a different 3/8 tee without a stop valve and used the adapter from this item to connect my Toto s5 Washlet bidet to my water supply. This would also work well and is pretty much plug and play. I just wanted less weight and didn't need an extra stop valve.
