American Standard 953950-0070A – Frequently Asked Questions
1) What is the American Standard R510 check stop with the blue marking used for?
It's the cold side check stop cartridge assembly for American Standard faucets. The blue marking identifies it as the cold inlet, so it pairs with a matching hot (red) stop on the opposite side. It's a genuine American Standard repair part sold for faucet service work, not a complete valve body.
2) Is the blue R510 check stop the hot or the cold side, and does it matter which side I install it on?
Blue is cold. On a two-handle American Standard faucet the stops are side specific by marking, so this one goes on the cold inlet. If you are rebuilding both sides, order the matching hot stop as well; one part number covers one side only.
3) What part number should I order for the American Standard blue cold check stop?
The manufacturer part number is 953950-0070A. It ships unfinished, since the stop sits inside the faucet body where finish is irrelevant.
4) How big is the American Standard 953950 check stop, and will it fit in a tight vanity cabinet?
The part measures 10.433 x 4.1 x 1 inches as packaged and weighs 0.134 pounds. The stop itself is a small cartridge style component, so the working clearance you need is inside the faucet body rather than under the sink.
5) Can I use this R510 check stop on a commercial restroom faucet, or is it residential only?
It is catalogued as a repair part rather than being restricted to one setting, and it is used by plumbers servicing American Standard faucets in either environment. The deciding factor is whether your faucet takes the R510 style check stop, not the building type.
6) Do I need any tools or extra parts beyond the check stop to finish the repair?
The stop is supplied as a drop in service item and installs without special tooling. Plan on shutting off the supplies and replacing both hot and cold stops together if the faucet is old, since a worn stop on the untouched side will usually be the next call back.
