American Standard 6066761.002 – Frequently Asked Questions
1) What rough-in does this touchless toilet flush valve need?
The Ultima Selectronic valve is set up for an 11-1/2 inch (292 mm) rough-in, measured from the supply centerline to the bowl spud centerline. Check that dimension on the existing carrier or stub-out before you swap valves, because a shorter or longer rough-in needs a different tube length.
2) Does this sensor flush valve need to be hardwired or run off a transformer?
No wiring. Power comes from a 10-year PWRX battery already installed inside the valve, so there's no transformer, no junction box, and no electrician on the install. That's the main reason this one gets specified for retrofits where there's no power at the fixture.
3) What happens to a touchless flush valve when the power or water pressure drops?
The valve fails safe: it closes automatically on loss of power or loss of water pressure, so it won't sit open and flood the fixture. There's also a fully mechanical manual override that flushes the bowl with no power at all, which is what maintenance staff use during a battery change or an outage.
4) How much water per flush does this dual flush valve use?
Dual flush, 1.6 gpf for solids and 1.1 gpf for liquids (6.0 and 4.2 Lpf). Sensor logic picks the volume based on how long the user is in front of the valve, so the reduced flush happens automatically without anyone pressing anything.
5) Our building has chronic flush valve run-on. Does this one address that?
Run-on usually starts when the refill orifice fouls with debris or scale. This Ultima valve uses DynaClean, an integral wiper spring that scrubs the refill orifice on every single flush, so the orifice stays clear without anyone pulling the valve apart. The body is a proprietary brass alloy that resists dezincification, which matters in aggressive or high-chloride water.
6) Is this a piston or a diaphragm flush valve, and which should I standardize on?
This is a piston-type valve. Piston valves use a single moving assembly rather than a rubber diaphragm and tend to hold up better in water with sediment or heavy mineral content. Diaphragm valves are more common and their rebuild kits are cheaper, so facilities already stocking diaphragm kits often stay with that style. If you're chasing repeat failures from dirty water, the piston design is the reason to switch.
7) Can I use this valve on a urinal?
No. This is a water closet flush valve, rated at 1.6/1.1 gpf and prepped for a 1-1/2 inch toilet spud. Urinals need a lower-volume valve with a 3/4 inch spud connection, so you'd need a separate Ultima urinal valve for those fixtures.
8) What finish does the Ultima Selectronic 6066761 come in?
Chrome only, ordered as part number 6066761.002. One finish, one configuration, so there's no handing or trim choice to specify on the order.
