American Standard 606B322.007 – Frequently Asked Questions
1) Does the Ultima 606B322 flush valve come with a power supply?
No. The power kit has to be ordered separately. The 606B322 ships as the concealed piston valve plus the wall box with a vandal-resistant brushed stainless cover, so budget a separate line item for the power source (transformer or battery kit) before the job goes to the plumber.
2) Can this concealed flush valve be serviced from behind the wall, or do I need front access?
Front access only. The 606B322 is specified for installations where the valve is reached through the wall box from the room side. If your chase design calls for rear access from an adjoining service corridor, this isn't the right configuration.
3) What happens if the power fails on the Ultima Selectronic concealed flush valve?
There's a fully mechanical manual override that flushes the valve with no power at all. That matters in a school, stadium, or healthcare restroom where an outage can't mean a dead fixture. The sensor handles normal touchless operation; the override is the backup.
4) How much water does the American Standard 606B322 flush valve use per flush?
1.28 gpf (4.8 Lpf), which is the high-efficiency water closet rate. Pair it with a 1.28 gpf rated flushometer bowl; putting a 1.28 valve on a bowl engineered for 1.6 gpf can leave you with carry problems.
5) What part number do I order for the base model Ultima concealed toilet flush valve?
Order manufacturer part 606B322.007 from American Standard's Selectronic family. It's the base-model concealed piston valve at 1.28 gpf with the wall box included, and it ships in a single configuration with no finish choice to specify (the exposed piece is the brushed stainless cover).
6) What keeps a sensor flush valve from running on continuously?
On the Ultima Selectronic, DynaClean self-cleaning wiper spring technology handles it. An integral wiper spring scrubs the refill orifice on every flush, which is where debris normally collects and causes a valve to run on. It's a piston-type valve, and the brass alloy is a proprietary blend that resists dezincification in aggressive water.
7) Is the American Standard 606B322 suitable for a high-traffic public restroom?
That's what it's built for. It's a commercial-group Selectronic flush valve, touchless to cut down germ transfer, and the wall box cover is vandal-resistant brushed stainless, so it holds up in open public restrooms where an exposed valve would get abused.
