American Standard M964905K-0071100A – Frequently Asked Questions
1) What is the American Standard M964905K-007 piston assembly used for?
It's the internal piston repair kit for a manual (handle-operated) American Standard toilet flush valve, rated at 1.1 gallons per flush. The piston is the moving part that opens and closes the valve on each flush, so this is the part you install when a diaphragm/piston flushometer starts running on, flushing short, or not shutting off. It's a toilet-side part, not a urinal part.
2) Will this piston work in a sensor-operated flushometer?
No. This piston assembly is specified for manual flush valves, the kind with a handle. Battery or hardwired sensor flushometers use a different operating assembly, so for a touchless valve you need the sensor-model repair part instead.
3) Can I use this piston to change my flushometer's flush volume?
It won't convert a valve to a different flush rate on its own. The piston is matched to 1.1 gpf operation, so use it where the valve is already a 1.1 gallon toilet flushometer. Dropping it into a valve built for a different volume is not what the part is specified for.
4) What is the American Standard part number for this 1.1 gpf manual toilet piston?
Order it by American Standard MPN M964905K-0071100A. That is the number to quote if you're stocking flushometer repair parts for a building and need to match the same piston across multiple fixtures.
5) Does this piston assembly come in a finish option?
No finish choice applies. It's an internal flush valve component that sits under the valve cover, so it ships as a single unfinished assembly, unlike the chrome exposed parts such as the cover cap or handle.
