American Standard M970451-0070A – Frequently Asked Questions
1) What are American Standard service stops M970451 used for in a shower valve?
They are the screwdriver stops that let you shut off hot and cold supply at the valve body itself, so you can service or swap the cartridge or trim without killing water to the rest of the building. American Standard sells them as a set of two, one per supply side, for Flash shower rough-in valves.
2) Do I get one stop or a pair with M970451-0070A?
The order is a set of two. A shower valve takes one stop on the hot inlet and one on the cold, so a single kit covers one valve body. For a multi-unit retrofit, count one kit per valve.
3) Can I add service stops to a Flash valve that was roughed in without them?
Yes, that is the usual reason to buy them. The stops install into the Flash rough-in valve body, so a valve set without them can be upgraded during a trim-out or a later cartridge service, giving you local shutoff at that shower from then on.
4) Are these stops for a tub and shower valve or lavatory supply?
Shower and tub service only. They are integral valve-body stops for the Flash rough-in, not angle stops for a lavatory or toilet supply line, so they will not substitute for a 1/4-turn supply stop under a sink.
5) Is there a finish choice on these American Standard service stops?
No finish option applies. The stops sit inside the valve body behind the escutcheon, so they ship unfinished under one part number, M970451-0070A. Nothing here affects the look of your trim.
6) Do I need a special tool to operate the M970451 stops?
A flat screwdriver. They are screwdriver stops, meaning each one is turned with a blade driver through the trim opening rather than by hand, which is why a tech can isolate the valve without pulling the whole escutcheon off the wall.
