DO NOT OVER TIGHTEN nuts or you could crack the fixture. My advice is to replace the water line that feeds the fixture, from the wall, at the same time. ## Frequently Bought Together - Sloan Flushmate Pressure Assist Flushing System, 1.6gpf - Flushmate M-101526-F31 FM III 503 Pressure Assist tank less Handle for most OEM 2 piece toilets using Flushmate - Original Replacement C-100500-K FlushmateCartridge/Power Flush Toilet Piston Cartridge Parts,Fits Model 500, 501, 501A, 501B, 503, 504 Series Flushmate Tank System。 --- ## 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/42482247-m-101526-f32-replacement-system-1-6-gpf-fits-kohler](https://www.desertcart.hr/products/42482247-m-101526-f32-replacement-system-1-6-gpf-fits-kohler) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-09-17*
