Under the blue cap just a few drops than it stops leaking. Is this a normal release of water when flushed ?** A: I would have been thrilled if mine had only leaked a few drops. Mine sprayed water like a fire hose so I returned it. **Q: Will this fit a Kohler 1.6 gallon toilet?** A: I see no reason why not, unless your tank is too low to put the tank lid or cover back on. check height of fill valve and tank depth **Q: Does this work with the toilets that does not have handles.. we have the one where you have to push the button in the center top of the tank.. Thanks** A: The part you are buying is the tube that refills the tank after the flush has occurred. Whether the flush is because of a handle or a button on the top of the tank. this unit is is separate from that action. The flapper valve included may or may not work with your tank but the unit itself to fill the tank over and over will work just fine. ## Frequently Bought Together - Fluidmaster K-400H-039 High Performance Toilet Fill Valve with 2-Inch Adjustable Toilet Flapper Kit - Hibbent Universal Metal Front Mount Toilet Handle Replacement Kit, Brass Toilet Flush Tank Lever with Stainless Steel Flapper Chains for Most Toilets, Chrome - Toilet Flush Handle Replacement Kit: Front Universal Toilet Bowl Replacement Kit, Toilet Repair Kit Inside Tank Chain Flusher Handle Lever Replacement Parts Compatible with American Standard Mansfield --- ## 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.us/products/431653417-k-400h-039-t14-performax-fill-valve-and-2-inch](https://www.desertcart.us/products/431653417-k-400h-039-t14-performax-fill-valve-and-2-inch) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-05-17*
