American Standard Single Control Faucet Replacement Valve Cartridge - AMS-A951470

The A951470 is a replacement valve cartridge for American Standard single control (single handle) faucets. It is the internal working part that mixes hot and cold and controls flow, not a complete faucet or a trim kit. You reuse the existing body, handle and escutcheon and swap only the cartridge, which is what a maintenance tech does when a single handle faucet drips, gets stiff to turn, or loses temperature control.

Order by manufacturer part number A951470-0070A, American Standard's own designation for this single control faucet cartridge. Property managers standardizing across a building should keep that number on the parts list, since American Standard single handle faucets use several different cartridges and they are not interchangeable by eye. Match the number stamped or documented for your faucet model before stocking it in quantity.

Usually yes, and that is exactly what this part is for. On a single control faucet the cartridge carries the seals and ports that wear out, so a drip, a stiff handle, or hot and cold bleeding together is generally a cartridge problem rather than a faucet problem. Replacing the A951470 cartridge keeps the existing body, spout and trim in the deck, which is faster than a full faucet swap and leaves the finish in the room unchanged. If the faucet body itself is cracked or the deck seal has failed, the cartridge will not solve it.

Yes, shut the stops under the sink (or the branch line if there are no stops) and open the faucet to relieve pressure before pulling the cartridge. The cartridge sits directly in the pressurized valve body, so removing it with the supply live will flood the cabinet. Have the replacement A951470 cartridge in hand before you open the faucet, since the fixture is out of service until it goes back together.
