American Standard 021943-0070A – Frequently Asked Questions

1) What size supply connection does the American Standard mechanical mixing valve 021943-0070A take?
The inlet supply size is 1/2 inch. That is the connection size you need on both the hot and cold side feeding the valve, so plan your stops and risers accordingly.
2) Is this American Standard mixing valve meant for a toilet or for a lavatory faucet?
It is a toilet application part. American Standard lists the AMS-21943 mechanical mixing valve under toilet repair parts, so it is used to temper the water supply feeding a fixture in that group rather than as a faucet body.
3) Does this American Standard mixing valve have built in backflow protection between hot and cold?
Yes. Duck bill checks are built into the valve, so hot and cold cannot cross feed through it when supply pressures are unbalanced. A 60 mesh strainer is also integral, which keeps grit and pipe scale out of the checks on older buildings with sediment in the lines.
4) Is the American Standard AMS-21943 mixing valve suitable for commercial restrooms or just residential?
It is built for commercial and institutional service. The body is metal rather than plastic and is described as rust resistant, which is what you want in a school, hospital, or multi family restroom where the valve sees constant duty.
5) Is this a thermostatic mixing valve?
No, it is a mechanical mixing valve. It blends hot and cold through a mechanical mix with duck bill checks and a strainer, not a thermostatic element. If your spec calls out a thermostatic or ASSE listed temperature limiting device, this is not that part.
6) Does the American Standard mechanical mixing valve come in different finishes?
No. It ships unfinished, since it is a concealed repair part rather than exposed trim. There is one configuration, part number 021943-0070A.
