American Standard M964905D-0070500A – Frequently Asked Questions
1) What does the American Standard M964905D-007 piston assembly fit?
It's the internal piston for an American Standard manual (non-electronic) urinal flush valve rated at 0.5 GPF. If the valve on the wall is a handle-operated American Standard urinal flushometer flushing at half a gallon, this is the rebuild piston for it. It is not a part for a closet (water closet) flush valve, and it is not for sensor-operated valves.
2) Will this piston work on a 1.0 GPF or 1.5 GPF urinal flush valve?
No. The piston is specified for 0.5 GPF manual urinal flush valves. Flush volume on a piston-type flushometer is set by the piston internals, so fitting a 0.5 GPF piston into a valve intended for a higher volume, or the reverse, changes how much water the fixture discharges. Match the piston to the rated flush volume stamped on the valve.
3) How many pistons come in American Standard part M964905D-007?
It ships as a blister pack of 100 pistons. That is a bulk maintenance quantity, not a single repair part, so it suits a facility crew or an MRO stockroom rebuilding urinals across a building rather than a one-off fix on a single fixture.
4) My urinal flushometer runs constantly or won't shut off. Is the piston the part to replace?
On a manual piston-type flushometer, a continuously running valve is usually the piston, its seals worn or fouled by debris so it can't reseat and close the valve. Swapping the piston assembly is the standard rebuild for that symptom on an American Standard 0.5 GPF manual urinal valve. Short or weak flushes point at the same part.
5) What part number do I order for the American Standard 0.5 GPF urinal piston?
The manufacturer part number is M964905D-0070500A, sold under American Standard's M964905D-007 designation. Give that number when matching a repair kit to an existing American Standard manual urinal flushometer.
6) Does the piston assembly come in different finishes?
No finish choice applies. The piston is an internal working part that sits inside the flush valve body behind the cap, so it is supplied unfinished in a single configuration. Finish selection only matters for the exposed valve body, cap, and handle.
