I am renting a single bedroom apartment that does not have a built-in dishwasher. So, I bought a countertop dishwasher. To feed water to it, I decided to get this valve to divert some of the hot water to the dishwasher. This was very easy to install and does the job pretty well. I thought that the knob would direct the flow of water between the faucet and the dishwasher. Nope. That knob is solely to control the flow of water out to the dishwasher. What a neat little gadget!

Exactly what I'm i needed. It was a struggle with local hardware stores getting something that wouldn't leak installing water lines to fridge. This did the job right. I would recommend if your having issues with leaks. Connections fit perfect with no leaks the first time and continue to work.

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.

I recently purchased this Brass Angle Stop Add-A-Tee Valve to install a countertop RO system in my kitchen without disrupting the existing faucet supply line. I’m not a plumber, but with a bit of DIY experience, I found the installation fairly straightforward. The build quality is solid—it’s made of brass, not cheap plastic like many other options out there, so it feels durable and long-lasting. The 3-way diverter worked exactly as described. I was able to maintain my 3/8" compression connection to the faucet while adding a second 1/4" line to feed the RO system. The threading was precise, and the compression fittings sealed well without leaks using just a little plumber's tape on the male threads for extra security. One minor issue: the valve handle is a bit small and stiff, especially when turning it on or off for the first time. Not a dealbreaker, but it took a little extra effort to operate, and I wish it had a more ergonomic grip. That said, once installed and adjusted, it has been working perfectly without needing any further tweaks. It’s great that it supports both 3/8" and 1/4" or 3/8" output sizes, giving flexibility depending on your water line or appliance setup—whether it’s a fridge, ice maker, or RO system. If you’re looking for a reliable and space-efficient way to split your cold water line, this is a great value and solid performer. Just be aware of the slightly tight valve control. Overall, very happy with it—4 stars.

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 Amazon 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!

This valve has solid construction and comes with all the parts you need. Make sure to use thread sealer or it will leak. Don’t blame the valve for bad installation

I needed to attach a hose from my Genie Bidet to my plumbing, but unfortunately there was no access to the bottom of the toilet tank on my American Standard Town Square toilet so I could not use the very nice tee valve provided with the Genie Bidet. Unfortunately the big box hardware stores had no easy solution, but then I found this tee connection with valve and adapter which solved my plumbing dilemma. The build quality seems good enough and I was careful to ensure the rubber seals were properly in place and I did not cross thread or over tighten the fittings. No leaks from the get go and after a month, still no leaks. Without this tee adapter I don't see how I could have put a bidet on this particular toilet. Thanks Amazon for making it available!

I used this in place of a saddle clamp (POS) for my RO water purification system. More reliable, less likely to leak, and easier to turn off/on the flow.

This YUHX brass angle stop tee valve is exactly what I needed to hook up both my TOTO Washlet and a handheld sprayer. It feels solid and well-made, with no cheap parts. The 3/8" x 3/8" x 3/8" connections were a perfect match for my setup, and installation was quick with no leaks at all. It’s great to have a clean-looking solution without needing extra hoses or adapters. The valve handle turns smoothly, and the brass construction gives confidence it’ll last. Highly recommended for any bidet setup!

Needed this so my Luxe Bidet 185 Neo could connect to the wall. We have stupid toilets that use 3/8 so I needed something to connect to the 1/2 that Luxe uses. No leaks. Didn’t even use plumber tape. Easy to install (recommend some pliers for final tighten twist). Good product. The switch a bit cheap feeling but who cares, I leave it in open position for my use case.

Great...Great...Great

Works great. Easy to install.
