American Standard R350 – Frequently Asked Questions

1) What is the American Standard R350 rough valve and do I need to order a faucet separately?
The R350 is the in-wall rough-in valve for the American Standard Serin wall-mount sensor faucet. It's the concealed half of the assembly that gets set in the wall during rough-in, so it is not a complete faucet. If you're doing a new install you order the R350 plus the Serin wall-mount faucet itself; if you're servicing an existing Serin wall-mount installation, the R350 is the buried valve behind it.
2) Will the American Standard R350 rough valve work with any wall-mount sensor faucet?
No. The R350 is specified as the rough valve for the American Standard Serin wall-mount faucet, and that's the pairing to buy it for. Don't spec it as a generic in-wall solenoid body behind another manufacturer's sensor spout or another American Standard series.
3) Is the American Standard R350 Serin rough valve lead-free for a potable water install?
Lead-free, yes. The Serin wall-mount faucet assembly the R350 serves contains less than or equal to 0.25% total lead content by weighted average, which is the threshold institutional and multi-family specs are usually written to.
4) What maintenance does the solenoid in the American Standard Serin wall-mount rough valve need once it's behind the wall?
The solenoid is self-cleaning: a wiper spring keeps the diaphragm hole clear on every use, and an easy-to-clean strainer ahead of it protects the solenoid valve. For an MRO or facilities crew that matters, because the valve body is buried and the strainer is the serviceable piece. Keep water clean at the strainer and you avoid opening the wall.
5) How does the Serin wall-mount sensor faucet handle vandalism or a sensor that gets blocked?
Two timers do that work through this valve. A safety timer shuts the faucet off when the sensor stays blocked for 55 seconds, so a taped or covered sensor can't run water continuously. A comfort timer keeps it from cycling on and off while someone is soaping their hands. The sensor itself is in the spout tip rather than a separate eye, which gives fewer exposed parts to attack, and it self-adapts its detection range to the surroundings.
6) Why does the American Standard R350 rough valve only come with no finish?
Because nothing on it is seen. The R350 sits inside the wall on a Serin wall-mount faucet, so it ships unfinished, in a single version, with one part number, R350. The finish decision belongs to the exposed spout, not to this valve, and you don't need to match a plated finish when ordering it.
