American Standard 6145SM101.002 – Frequently Asked Questions
1) Does the Ultima touchless urinal flush valve need to be hardwired, or does it run on batteries?
Battery powered. Four C-sized alkaline batteries ship with the valve, so there's no transformer, low-voltage wiring, or electrician needed at the fixture. That's the practical reason a lot of property managers pick this one for retrofits into existing restrooms where there's no power behind the wall.
2) Is a 1.0 gpf urinal valve going to flush properly on an older 1.5 or 3.0 gpf urinal?
The Ultima 6145SM101 is fixed at 1.0 gpf / 3.8 Lpf. Match it to a urinal rated for 1.0 gallons per flush or less. Dropping a 1.0 gpf valve onto an older high-consumption fixture designed around 1.5 or 3.0 gallons can leave waste in the trap, so check the fixture's rated flush volume first.
3) Can someone flush this urinal valve manually if the sensor doesn't pick them up?
There's an electronically operated override button on the valve. Pressing it triggers a flush through the solenoid, so it isn't a mechanical handle bypass, it still needs battery power. Useful for cleaning crews walking a row of urinals.
4) Why do sensor urinal valves run on and how does this one prevent it?
Run-on usually starts when the refill orifice in the diaphragm silts up and the diaphragm can't reseat. This valve uses DynaClean, an integral wiper spring that scrubs that orifice on every flush. The diaphragm itself is EvoLast material, made to resist chlorine and chloramine in municipal water that chews up standard rubber diaphragms.
5) Is this a diaphragm or a piston flush valve, and does it matter for my water quality?
Diaphragm type. Diaphragm valves are the common commercial choice and the rebuild is a diaphragm kit rather than a piston assembly. American Standard specs a chlorine- and chloramine-resistant diaphragm here, which is the wear part to watch in hard or heavily treated water.
6) How much clearance do I need around the urinal for this sensor flush valve?
Plan for roughly 11-1/4 inches of length and width and about 10-1/8 inches of height on the packaged unit. On tight partition layouts, check the distance from the urinal centerline to the adjacent screen before you commit, since the sensor face and cover need to sit clear of the panel.
