American Standard 606B361.007 – Frequently Asked Questions
1) Does the American Standard 606B361 Ultima Selectronic flush valve come with a power supply?
No. The power kit is sold separately on the 606B361, so budget for it on the order or the valve will not operate on sensor. The unit does include a fully mechanical manual override that flushes without power, which is what keeps a restroom running through an outage, but it is not a substitute for the power kit in day to day touchless use.
2) What spud size toilet does the Ultima Selectronic concealed flush valve fit?
It is built for flushometer bowls with a 1-1/2 inch (38 mm) exposed back spud. If the bowl on your opening has a top spud or a different spud diameter, this valve is the wrong part for it.
3) Can this concealed flush valve be serviced if there is no chase behind the wall?
Yes, the 606B361 is specified for installations with front access. Service happens through the wall box, which ships with a vandal-resistant brushed stainless steel cover, so a maintenance tech works from the restroom side rather than needing a walk-in chase.
4) Does this flush valve meet a 1.6 gallon water closet spec?
It flushes at 1.6 gpf / 6.0 Lpf, the standard commercial water closet volume, so it pairs with a 1.6 gpf flushometer bowl. It is not a 1.28 gpf high-efficiency valve, so if the project spec calls for HET volume you need a different model.
5) What stops a sensor flush valve like this from running on continuously?
The Ultima Selectronic uses American Standard's DynaClean self-cleaning wiper spring. An integral wiper spring scrubs the refill orifice on every flush, which is the orifice that clogs with debris and causes valve run-on in hard or dirty water. That is the main reason this piston-type valve is specified in high-traffic facilities over a valve with no orifice cleaning.
6) Will this valve hold up in aggressive water without the brass corroding?
The valve body uses a proprietary brass alloy that resists dezincification, which is the zinc leaching failure that pinholes ordinary brass in aggressive or chlorinated water. For a school, hospital, or stadium restroom being standardized on one valve, that is the durability claim to hang the decision on.
7) Is the AMS-606B361 a residential or commercial flush valve, and what part number do I order?
Commercial. It is the base model of the Ultima Selectronic concealed toilet flush valve family, ordered as manufacturer part number 606B361.007, with no plated finish option since the exposed element is the stainless wall box cover rather than the valve itself.
