Apparently, it was a different issue, the taller narrow thing to the left of this flush valve. I have zero confidence in some handymen - even the diagnosis was wrong. My motto is, generally, do it yourself and it will get done right. Review: Don't be afraid. It's not that hard to replace it yourself. - Quite pleased with myself for installing. Youtube helped. The toilet works great now. Being a 65+ female accountant this job was a bit foreign to me. I didn't realize until I got the toilet tank off that if you are going thru the trouble of replacing the flush valve then you really should get a new gasket kit as well. It took another day for the gasket to arrive but in the end my toilet is poised to be working well for the next 10+ years. ## Features - For use with American Standard Champion ONE-PIECE toilet- Check your model for compatibility - Compatible with 2034314-Champion 4 One-Piece 1.6 gpf/6.0 Lpf Chair Height Elongated Toilet With Seat - Compatible with 2004314-Champion 4 One-Piece 1.6 gpf/6.0 Lpf Standard Height Elongated Toilet With Seat - Easy to install- installation video available on our website ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00263YXYI | | Best Sellers Rank | #102,627 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #136 in Toilet Flush Valves #8,924 in Kitchen & Bath Fixtures | | Brand | American Standard | | Brand Name | American Standard | | Connector Type | Barb | | Customer Reviews | 4.3 out of 5 stars 1,186 Reviews | | Exterior Finish | Chrome | | Global Trade Identification Number | 00012611413728 | | Included Components | Flush Valve Assembly | | Inlet Connection Size | 4 Inches | | Inlet Connection Type | Barb | | Item Dimensions | 4.6 x 5.7 x 6.8 inches | | Item Type Name | Flush Valve Assembly for 1 Piece Toilets | | Item Weight | 113 Grams | | Item dimensions L x W x H | 4.6 x 5.7 x 6.8 inches | | Manufacturer | AMMM9 | | Manufacturer Part Number | 3280.040-0070A | | Manufacturer Warranty Description | β€œ*1 year Limited warranty from date of purchase” | | Material | Plastic | | Material Type | Plastic | | Model Number | 3280.040-0070A | | Number of Ports | 1 | | Outlet Connection Size | 4 Inches | | Outlet Connection Type | Barb | | Size | 6.40 in wide x 7.00 in tall x 10.3 in deep | | Smart Home Compatibility | Not Smart Home Compatible | | Specification Met | WaterSense | | Thread Size | 4 inches | | Thread Type | National Pipe Thread (NPT) | | UPC | 012611413728 | | Unit Count | 1.0 Count | | Valve Type | flush valve | ## Product Details - **Material:** Plastic - **Brand:** American Standard - **Item dimensions L x W x H:** 10.3 x 7 x 6.4 inches - **Exterior Finish:** Chrome - **Inlet Connection Size:** 4 Inches - **Inlet Connection Type:** Barb - **Outlet Connection Type:** Barb - **Number of Ports:** 1 - **Outlet Connection Size:** 4 Inches - **Specification Met:** WaterSense ## Images ![American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One-Piece Toilets(Compatible ONLY with SELECT Champion 4 One-Piece toilet), Black - Image 1](https://m.media-amazon.com/images/I/515jk4bk9iL.jpg) ![American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One-Piece Toilets(Compatible ONLY with SELECT Champion 4 One-Piece toilet), Black - Image 2](https://m.media-amazon.com/images/I/519D0mgjf3L.jpg) ![American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One-Piece Toilets(Compatible ONLY with SELECT Champion 4 One-Piece toilet), Black - Image 3](https://m.media-amazon.com/images/I/61-tSxRCK+L.jpg) ![American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One-Piece Toilets(Compatible ONLY with SELECT Champion 4 One-Piece toilet), Black - Image 4](https://m.media-amazon.com/images/I/51GUP3lXMlL.jpg) ![American Standard 3280.040-0070A 4-Inch Flush Valve Assembly for Champion One-Piece Toilets(Compatible ONLY with SELECT Champion 4 One-Piece toilet), Black - Image 5](https://m.media-amazon.com/images/I/61KZVUVdhTL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works fine, like the original. *by A***S on April 13, 2026* It works, but the squeal persisted.
