Ordered this one but installed another plastic one while I waited for it to arrive. It arrived and the new plastic valve failed... weird. But installed the brass one and it is working great. ## Frequently Bought Together - 1 1/4-Inch Check Valve,Female NPT,No-Lead Brass,Female Pipe Thread Compatible with Most Pumps,Silent Check Valve,Prevents Backflow in Well or Irrigation Systems - VEVOR Deep Well Submersible Pump, 1HP 115V/60Hz, 37gpm Flow 207ft Head, with 33ft Electric Cord, 4" Stainless Steel Water Pump for Industrial, Irrigation&Home Use, IP68 Waterproof Grade - SIMMONS 1350 Rubber Torque Arrestor, 1" to 1-1/4" --- ## 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.co.za/products/447201432-1-1-4-inch-check-valve-1-25-female-npt](https://www.desertcart.co.za/products/447201432-1-1-4-inch-check-valve-1-25-female-npt) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-04*
