American Standard 6145101.002 – Frequently Asked Questions
1) Is the Ultima manual urinal flush valve ADA compliant?
The handle is ADA-compliant and non-hold-open, meaning it shuts off automatically after every flush rather than requiring the user to keep pressure on it. That matters for accessible fixtures in schools, healthcare and public restrooms where operable parts have to work without tight grasping or sustained force.
2) How much water does the Ultima 6145101 urinal flush valve use per flush?
1.0 gpf (3.8 Lpf). That's a standard water-conserving urinal rate, so if your fixture is rated for 1.0 gpf it's a direct match. A urinal designed for 0.5 gpf or 0.125 gpf will get more water than it needs, and a pre-1990s 1.5 gpf or higher urinal may not clear the trap properly with this valve.
3) Can this flush valve be installed with the supply coming in from either side?
Yes, the valve installs left- or right-handed, so you don't have to specify handing when you order. Useful in a multi-stall restroom where the carrier and supply locations alternate across a row of urinals.
4) Is this a manual flush valve or a sensor flush valve?
Manual. The 6145101 uses a push handle, no battery, no solar cell, no wiring. If you are standardizing a restroom on touchless operation you want a sensor-operated Ultima instead. Manual is what most property managers stay with for retrofit work because there is no power to run and no sensor to fail.
5) What causes urinal flush valves to run on constantly, and does this one address it?
Run-on is usually a fouled refill orifice in the diaphragm. This valve uses DynaClean, an integral wiper spring that scrubs the refill orifice on every flush, plus an EvoLast diaphragm made to resist chlorine and chloramine so it doesn't harden and fail early. Both are aimed at the two failure modes that put a maintenance tech back on the same fixture.
6) Is this a diaphragm valve or a piston valve, and does that change the repair parts I stock?
Diaphragm-type. Rebuild kits for diaphragm valves are not interchangeable with piston-type valves, so if your building is already standardized on diaphragm valves this one keeps your spare parts consistent. Mixing the two across a restroom means carrying two different rebuild kits.
7) Will this valve hold up in hard or aggressive water?
The body is a proprietary brass alloy that resists dezincification, which is the failure where zinc leaches out of ordinary brass and leaves a porous, weakened casting. It also carries a high back pressure vacuum breaker to help prevent dripping at the spud connection.
8) What finish does American Standard part 6145101 come in?
Polished chrome, ordered as 6145101.002. That's the only finish offered on this model, and it's the standard match for commercial restroom trim and exposed supply stops.
