Review: Excellent Product - I have two bathrooms and both of the flush valves suffered from the same issue. They would not stop running. I received a replacement for one of them under warranty and the replacement was one of this model. It worked perfectly so I decided to order TWO more of the exact same model. One in a spare and the other was installed in my second bath room. Could not be happier with the installation, and performance. I am 78 and the toilets are not easy to get to. But the installation was so simple that even I could do it. Review: Muy buena - De muy buena calidad ## Features - Easy-to-install - EZ twist height adjusts from 9 to 14 in to fit most tanks. - Set of 2 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00G9OGNKC | | Brand | Fluidmaster | | Brand Name | Fluidmaster | | Customer Reviews | 4.6 out of 5 stars 158 Reviews | | Exterior Finish | Plastic | | Exterior finish | Plastic | | Included Components | Fluidmaster - 39961000026 | | Inlet Connection Size | 0.88 Inches | | Inlet Connection Type | Fill | | Inlet connection size | 0.88 Inches | | Inlet connection type | Fill | | Item Dimensions | 7.6 x 7.6 x 31.8 centimeters | | Item Type Name | Fluidmaster - 39961000026 | | Item Weight | 1 Pounds | | Item dimensions L x W x H | 7.6 x 7.6 x 31.8 centimeters | | Item height | 12.5 inches | | Manufacturer | Fluidmaster | | Material | Plastic | | Material Type | Plastic | | Model Number | Fluidmaster - 39961000026 | | Number of Ports | 1 | | Outlet Connection Size | 0.88 Inches | | Outlet Connection Type | Fill | | Specification Met | IAPMO, UPC | | UPC | 685784211974 758399396678 | | Unit Count | 2.0 Count | | Valve Type | Toilet Fill Valve | ## Product Details - **Brand:** Fluidmaster - **Inlet Connection Size:** 0.88 Inches - **Inlet Connection Type:** Fill - **Item dimensions L x W x H:** 3 x 3 x 12.5 inches - **Manufacturer:** Fluidmaster - **Material:** Plastic - **Number of Ports:** 1 - **Outlet Connection Size:** 0.88 Inches - **Outlet Connection Type:** Fill - **Specification Met:** IAPMO ## Images ![400A Toilet Tank Repair Fill Valve - 2 Pack - Image 1](https://m.media-amazon.com/images/I/51iNxfe3yBL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Excellent Product *by B***I on 28 December 2023* I have two bathrooms and both of the flush valves suffered from the same issue. They would not stop running. I received a replacement for one of them under warranty and the replacement was one of this model. It worked perfectly so I decided to order TWO more of the exact same model. One in a spare and the other was installed in my second bath room. Could not be happier with the installation, and performance. I am 78 and the toilets are not easy to get to. But the installation was so simple that even I could do it. ### ⭐⭐⭐⭐⭐ Muy buena *by C***M on 30 September 2024* De muy buena calidad ### ⭐⭐⭐⭐⭐ Fixes that ghost toilet *by B***Y on 26 June 2020* We have three American Standard toilets and all had issues with water continuously running. I was going to bite the bullet and call a plumber when youtube came to the rescue. Watched a 10-min video, identified our toilets as being American Standard, and ordered these parts. Shipping was fast and install a breeze and success; no more running toilets. Life span is from 2-3 years so I purchased a few as spares. ## Frequently Bought Together - Fluidmaster 400A Toilet Tank Repair Fill Valve - 2 Pack - Fluidmaster 218 Toilet Refill Tube and Clip Replacement, For 100,200,200A, 400A and Most Other Valves , Black --- ## 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.kr/products/378425643-400a-toilet-tank-repair-fill-valve-2-pack](https://www.desertcart.kr/products/378425643-400a-toilet-tank-repair-fill-valve-2-pack) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-07-12*
