OEM Flush Valve For Gerber 99-648

This is an Original Equipment Manufacturer (OEM) Replacement Flush Valve for the Gerber 99-648 flush valve.

Includes an OEM replacement flush valve body with locking nut and gasket, 2” 99-647 OEM replacement flapper, refill tube, and installation instructions. This does NOT include a tank to bowl gasket or any hardware between the toilet tank and toilet bowl.

Used in various 2 piece Gerber toilets. Can be used in MOST variants of the following tanks: 28-490, 28-492, 28-494, 28-790, 28-794, 28-795. Model and part information is typically printed inside of the tank.

Check the height of the existing fill valve and flapper size to verify fit. The Flush Valve Body is 9 7/8” high from the bottom of the base to the top of the overflow tube. Overflow tube (shank) is 8 1/8” high from the bottom of the overflow tube to the top of the overflow tube. Because each individual toilet varies slightly, some adjustment of the included stainless steel chain on the flapper may be required.

Note that the exact color and shape of components may vary slightly due to minor revisions of the parts by Gerber although this product is backwards compatible with older revisions of the same part with identical or improved performance. 

Comes in an economical plastic bag and clamshell with cost savings passed on to the customer. Meets or exceeds all applicable US and Canadian Plumbing Standards.
