American Standard M954319-0070A – Frequently Asked Questions

1) Will the American Standard Ultima diaphragm kit work on a Sloan or Zurn flush valve?
Yes. The Ultima diaphragm assembly, part M954319-0070A, is built to retrofit Sloan and Zurn diaphragm-type flushometers as well as American Standard Ultima valves. It swaps in through the top of the valve body once the cover is off, so the valve stays on the wall and the supply stays connected.
2) Does one Ultima diaphragm kit cover both 1.6 GPF toilets and 1.0 GPF urinals?
It is sold for both. The kit is specified for 1.6 GPF water closet flushometers and 1.0 GPF urinal flushometers, so a facility running both fixture types can stock a single repair part instead of two.
3) Does the diaphragm kit include the trip mechanism, or do I have to order that separately?
The trip mechanism comes with it. Kits are furnished complete with the closet or urinal trip mechanism, so you are not sourcing a separate relief valve assembly to finish the repair.
4) Is this a full flush valve replacement or just the internal repair part?
Internal repair part only. It is the diaphragm seal assembly that goes inside an existing flushometer, not a complete valve, and it does not include the valve body, cover, handle, vacuum breaker, or spud coupling. If the chrome body itself is damaged or the threads are stripped, you need a complete flushometer instead.
5) Can I put this diaphragm in a piston-type flushometer?
No. This is a diaphragm assembly and it only fits diaphragm-operated flushometers. Piston-style valves use an entirely different internal cartridge, and forcing a diaphragm kit into one will not seal. Pull the cover and confirm you are looking at a rubber diaphragm before you order.
6) My flushometers keep running or double-flushing on chloraminated water. Will this diaphragm hold up?
That failure is usually a diaphragm that has hardened or torn, or grit lodged in the bypass. The Ultima diaphragm is made chemical resistant and clog resistant for exactly that duty, which is why it is a common standardization choice for schools, stadiums, and other high-traffic restrooms on treated municipal water.
7) Will a 1.6 GPF diaphragm kit change the flush volume on my urinal?
Flush volume is set by the diaphragm and relief valve you install, so match the kit to the fixture. Order it for urinal service on a 1.0 GPF urinal and for closet service on a 1.6 GPF water closet. Using the wrong one either short-flushes the bowl or over-uses water at the urinal.
8) What is the exact part number for the American Standard Ultima diaphragm assembly?
Order by manufacturer part number M954319-0070A. It is an internal repair kit, so it carries no decorative finish, and there is a single configuration rather than a range of options to specify.
