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! ## Frequently Bought Together - Pentair R172086 1/2-Inch Control Valve Replacement Rainbow Automatic Chlorine/Bromine Pool and Spa Feeder - Inline Poppet Check Valve 685 Series PP 1/2 FPT - BUNA - Banjo NIP050-SH Polypropylene Pipe Fitting, Short Nipple, Schedule 80, 1/2" NPT Male, 1-3/4" Length --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.es/products/15420622-pentair-r172086-1-2-inch-control-valve-replacement-rainbow-automatic](https://www.desertcart.es/products/15420622-pentair-r172086-1-2-inch-control-valve-replacement-rainbow-automatic) --- *Product available on Desertcart Spain* *Store origin: ES* *Last updated: 2026-09-05*
