My toilet ran like a whisper before--then I used this replacement valve kit and the toilet works--REALLY LOUD. It wakes people up in the other room (the bathroom is connected to the master bedroom). Get a better version from someplace else like Lowes or Home Despot. **Q: Will this work on my Costco WaterRidge-c22148c toilet?** A: No. This is not the correct piece. **Q: How do you secure the valve to the screw** A: The top half of the flush valve twists off exposing the screw and metal piece that will hold the valve down. Loosen the screw allowing you to fit the bracket into the water drain and then tighten up the screw which will tighten up the flush valve. Then twist and lock the the rest back. ## Frequently Bought Together - Toilet Flush Valves 2-Inch Replacement Valve Kit Assembly for One Piece Dual Flush Drain Valve Repair Compatible with TOTO THU338N - Teaayako Toilet Push Button 38mm Thread Diameter Dual Push Flushing Button Adjustable Toilet Water Tank Button,Black - Fluidmaster 400H-002 Performax Universal Toilet Fill Valve High Performance Tank and Bowl Water Control, 1-Pack, Multicolor --- ## 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.tn/products/217759070-2-inch-toilet-flush-valves-assembly-compatible-with-water-ridge](https://www.desertcart.tn/products/217759070-2-inch-toilet-flush-valves-assembly-compatible-with-water-ridge) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-09*
