## Description

Pentair R172086 1/2-Inch Control Valve Replacement Rainbow Automatic Chlorine/Bromine Pool and Spa Feeder

Review: When you need this, you need it! - Our dial broke, and luckily, this is the exact replacement. Easy swap out.
Review: Good valve but the problem might be the check valve too - I bought this item because I could not stop the flow of water into the in-line chlorine feeder even when I turned it to 0. I replaced the valve and I still couldn’t stop the water by shutting off the valve. There is a check valve (Pentair R172248) under the plastic screen at the bottom of the feeder. I replaced that check valve and the plastic screen (Pentair R172255) and now it works perfectly. My original shut-off valve was probably still working but this one is working good now. There is also a screw in the bottom of the feeder under the valve that needs to be loosened before unscrewing the feeder body.

## Questions & Answers

**Q: Is this directional? I don’t see any arrows stating so.**
A: Uncertain. I installed same direction/position as my old one

**Q: Why did this item go up by 49.5% in less than 2 months?**
A: Because soft wash has exploded and everyone is buying these it sucks. And I hear these are not very reliable. A lot of defective ones getting through but it's still cheaper than the other options

**Q: At 5 does t provide full flow through the valve or is it still somewhat restricted?**
A: A large volume of water flows through and, without testing, I would say it is full flow.

**Q: Do the numbers represent percentage?**
A: I'd say yes, if you look at the actual valve inside, off is closed , each number is the valve opening more and more until its fully opened. This valve is real Pentair,, buy this .Others on Amazon are cheap knock offs with wrong threads, won't work. This will!

### ⭐⭐⭐⭐⭐ When you need this, you need it!

### ⭐⭐⭐⭐⭐ Good valve but the problem might be the check valve too

### ⭐⭐⭐⭐⭐ Great Fit
*by B***E on September 6, 2024*

It is an exact replacement. For those that say they crack when installed this part is a tool less installation. All you need is Teflon tape and your hands. You don't need to get on there with both feet. It adjusts smoothly and better than the original that was installed.
