American Standard 953951-0070A – Frequently Asked Questions
1) Is the American Standard 953951 check stop the hot side or the cold side?
It's the hot side. The red marking identifies it as the hot check stop for the R510 valve, so if you're rebuilding both sides of a fitting you'll need the cold (blue) check stop as a separate part.
2) What part number do I order for the American Standard hot check stop?
The manufacturer part number is 953951-0070A. It ships as a plain repair part with no decorative finish, since the check stop sits inside the valve body where it isn't seen.
3) Will this check stop work on any American Standard faucet, or only certain valves?
It is specific to the American Standard R510 valve. Check stops are not universal between valve platforms, so confirm the rough-in body in your wall is an R510 before ordering. If it's a different American Standard valve series, the check stop for that series is a different part.
4) Is this a genuine American Standard part or an aftermarket copy?
Genuine American Standard repair part, the same component plumbers use when servicing American Standard fittings rather than a generic equivalent.
5) Should I replace both check stops at once when rebuilding an R510 valve?
Usually yes. The hot and cold stops age at the same rate, and hot-side stops in particular wear faster from thermal cycling. This one covers the hot side only, so pair it with the cold check stop if you want the valve fully rebuilt in a single trip. For a facility standardizing on American Standard, keeping both on the truck avoids a second visit.
6) Can a maintenance tech swap this check stop, or does it need a plumber?
It's a plumber-grade repair part but a straightforward one, meant for in-place service of the existing R510 rough-in with no wall work. Shut the supply, pull the trim and cartridge, and the check stop comes out of the valve port. Property maintenance crews who already service their own mixing valves can handle it.
