On the original there is a hole beside the inlet and outlet. This is what turns the valve on when you twist it into place. This supposed copy doesn’t have that so it doesn’t work. It also took 2 weeks to arrive and now I have to send it back and order a different brand. ## Frequently Bought Together - AQUA CREST RC 4 EZ-Change Premium Water Filter Replacement, Replacement for Culligan RC-EZ-4, IC-EZ-4, US-EZ-4, RC-EZ-3, DuPont WFQTC30001, WFQTC70001, 2K Gallons (Pack of 1) - AQUA CREST RC 1 EZ-Change Basic Water Filtration Replacement, Replacement for Culligan IC-EZ-1, US-EZ-1, RV-EZ-1, Brita USF-201, USF-202, DuPont WFQTC30001, WFQTC70001, 3K Gallons (Pack of 2) - AQUA CREST RC 3 EZ-Change, WFQTC30001, WFQTC70001 Advanced Water Filter Replacement, Replacement for Culligan RC-EZ-3, IC-EZ-3, US-EZ-3, RC-EZ-1, Brita USF-201, USF-202, DuPont, 2K Gallons (Pack of 2) --- ## 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.hr/products/329910452-aqua-crest-rc-4-ez-change-premium-water-filtration-replacement](https://www.desertcart.hr/products/329910452-aqua-crest-rc-4-ez-change-premium-water-filtration-replacement) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-04-24*
