Review: Perfecto para mis necesidades
Review: Should have tried something with more reviews. - The male thread on the ball valve part is actually 1/2, not 1/4. And the male and female threads of the straight tube are both 3/4, not 1/2. I don't know if I received the wrong one or not. But I was able to connect it to a different part under my sink, which still allows it to serve its purpose. However, it leaks, I think due to poor design. Because these are two separate parts, once you screw in the ball valve part into the straight tube, it extends about halfway inside the tube. What happens is some water is being blocked by that overextension inside and thus some water being pushed under the overextension and out, creating a leak. I was able to slow it significantly by using A LOT of teflon tape and tightening it hard to where it's not a big issue, but I'll replace it down the line and try something else.

## Questions & Answers

**Q: does this connect to the kitchen faucet connection on the bottom where your water line goes?**
A: Yes. The water pipe coming out of the wall connects to a flexible tube that goes up to the faucet...this is inserted in between that connection.
