American Standard M955058-0020A – Frequently Asked Questions
1) What is the American Standard M955058 supply stop, and what does it do?
It's a 3/4 inch supply stop from American Standard, part number M955058-0020A, in polished chrome. A supply stop is the shutoff valve on the water supply line feeding a fixture, so you can isolate that one fixture and service it without killing water to the rest of the building. This is the 3/4 inch size, which is a supply main or larger-branch size rather than the 3/8 inch and 1/2 inch sizes used on most lavatory and toilet risers.
2) Will a 3/4 inch supply stop work on my toilet or lavatory riser?
Probably not. Standard toilet and lavatory supplies run 3/8 inch or 1/2 inch, and the M955058 is a 3/4 inch stop. If you're replacing the angle stop under a water closet or sink, you want the smaller size. The 3/4 inch stop belongs on larger supply runs, water heater feeds, and similar branch lines.
3) Is M955058 a repair part for an existing American Standard fixture or a standalone valve?
It's sold as a repair part, an American Standard service item for replacing the 3/4 inch supply stop on their fixtures. If you're servicing an American Standard installation and the stop has failed or is weeping at the packing, this is the factory replacement rather than a generic aftermarket valve. Order it by the American Standard number, M955058-0020A.
