American Standard M964938-0020A – Frequently Asked Questions
1) What is the American Standard M964938 vacuum breaker connection kit used for?
It's the vacuum breaker connection kit for a toilet flush valve installation, ordered as American Standard part M964938-0020A in chrome. The vacuum breaker is the backflow protection piece that sits between the flushometer and the fixture spud, and the kit covers that connection.
2) Is this American Standard kit for a top spud or back spud toilet?
Top spud only. The M964938 kit is the top spud version, so it suits a floor-mounted or wall-hung bowl with the flush connection entering through the top of the fixture. A back spud bowl, where the connection comes in horizontally from the wall, takes a different vacuum breaker connection assembly.
3) I have a leaking vacuum breaker on my American Standard flush valve - is this the repair part?
Yes, for a top spud water closet installation. The M964938-0020A kit is the vacuum breaker connection assembly, which is the usual replacement when the breaker is spitting or weeping at the tube. Confirm your fixture is top spud before ordering, since the back spud assembly is a different part.
4) Can I use this on a urinal instead of a toilet?
The M964938 connection kit is specified for toilet (water closet) service. Urinal flushometers use a smaller connection, so order the urinal-specific vacuum breaker kit for that fixture rather than this one.
5) What finish does the M964938 vacuum breaker kit come in?
Chrome, and that is the only finish it's built in. Part number M964938-0020A. If the rest of the exposed flushometer trim on the fixture is polished chrome, this matches; on a brushed or rough-brass flushometer it will not.
