AO Smith APCOM UT1 Under-Sink Hot Water Recirculation Pump | Instant Hot Water

Instant Hot Water, When You Need It

The AO Smith APCOM UT1 is an under-sink hot water recirculation pump designed to bring warmth to your taps faster. Its compact profile hides neatly beneath the sink while the system quietly works behind the scenes, delivering comfort without the typical wait.

Built for homes with a single hot water line and without a dedicated return line, the UT1 can serve up to 250 feet of piping. The pump runs automatically in short bursts—usually three to four times per hour for one to two minutes—thanks to a built-in thermostat and timer. This thoughtful design helps minimize water waste and keep hot water within reach where you need it most.
