TOTO T28S32ET#CP – Frequently Asked Questions
1) Will the TOTO Standard R touchless faucet fit a single-hole sink deck?
Single-hole, deck-mount is exactly what the Standard R is built for. It requires one faucet hole and mounts through the deck, with a maximum deck thickness of 2 inches. If your lavatory or countertop is thicker than 2 inches at the mounting point, the shank won't pull down onto it, and a 3-hole deck needs an escutcheon plate to cover the outer holes.
2) Does the TOTO Standard R sensor faucet need to be hardwired, or can it run on battery?
Both are offered. The AC powered version needs a 120V AC supply run to the operating controller, so an electrician has to get power under the lavatory. The EcoPower version is self-generating and ships with a lithium ion battery included, which is the one to specify on a retrofit where there is no power under the sink and cutting into finished walls isn't an option.
3) What supply connection does the TOTO Standard R faucet use, and what else do I need to buy to install it?
The connection is G 1/2, and the supply lines are not in the box. You get the spout, operating controller and mounting hardware; you buy the supply line for the G 1/2 connection separately. A drain is also not included, so budget a pop-up or grid drain per opening. On an AC unit, add the 120V power run.
4) How do I mix hot and cold on a TOTO Standard R touchless faucet? Is a mixing valve included?
A valve comes with the faucet, and you choose which type. The mixing valve option blends hot and cold at a manually set ratio. The thermostatic mixing valve option holds outlet temperature against supply swings, which is what healthcare, education and other institutional specs usually call for on public lavatories. There is also a no-valve configuration for a single-temperature supply, typically tempered water off a central mixing valve.
5) Does the TOTO Standard R faucet meet CALGreen and California CEC flow requirements?
Yes, the Standard R is CEC and CALGreen compliant, and it is ADA compliant. Flow rates offered run 0.35, 0.5 and 1 GPM, so for a California job or any project chasing water-efficiency credit, specify the 0.35 or 0.5 GPM configuration rather than the 1 GPM.
6) Will a TOTO Standard R touchless faucet clear the basin on a small lavatory or a vessel sink?
Reach is 4.63 inches and spout height is 3.63 inches. That is a low, short-reach profile suited to a standard drop-in or undermount lavatory bowl. On a vessel sink sitting proud of the deck, 3.63 inches of spout height will not clear the rim, so a vessel-height sensor faucet is the right call there.
7) What is the difference between the 10 second on-demand and 20 second continuous flow on the TOTO Standard R?
On-demand means water runs only while hands are under the spout and stops the moment they leave, so it cannot be left running. At 0.5 GPM the on-demand cycle uses 0.08 gallons. The 20 second continuous version runs a fixed timed cycle once triggered. For high-traffic restrooms where water waste and vandalism are the concern, on-demand is the tighter choice; continuous suits handwashing protocols that want a set duration without re-triggering.
8) Can I get TOTO Standard R sensor faucets to match the rest of my restroom trim?
Three finishes are offered across the Standard R: Brushed Nickel, Polished Chrome and Polished Nickel. For a facility standardizing across many restrooms, Polished Chrome is the usual match to existing commercial trim, and the same three finishes carry across the power, flow and valve configurations so a fleet can be specified in one finish.
9) What replacement parts go with the TOTO Standard R touchless faucet?
The Standard R is built around three service components: TLE28001U2#CP, TLE03501U2 and TLE05701U. Those are the numbers to quote when a maintenance tech needs to rebuild rather than replace a faucet, which is the usual path on an MRO account with dozens of identical lavatories.
10) Do I have to aim my hands at a sensor eye on the TOTO Standard R, and where is it?
The sensor sits underneath the spout head, concealed inside the spout body, so users put their hands under the outlet the way they would with any faucet and the water starts. There is no side-mounted eye to hunt for, which is what cuts down repeat waving and complaints in high-traffic public restrooms.
