Why it matters
The UT1 comes as a kit: a stainless pump, two braided hoses, two tees and fittings that install under the sink in about 10 minutes with one wrench. A built-in thermostat and timer typically run it three to four times an hour for one to two minutes.
It's designed for homes without a dedicated hot water return line and up to 250 ft of piping, with a standard tank or indirect water heater.
Who it's for, and who should skip it
Good fit if
- DIY installs
- Homes without a return line
- Tank water heaters
Look elsewhere if
- Tankless heaters
- Sinks without an outlet
Pros and cons
Pros
- Complete kit
- Thermostat and timer
- Stainless pump
Cons
- Outlet needed
- Pricier
- Cold tap can run warm
Limitations to weigh
- Under-sink recirculation without a return line sends warm water back through the cold line, so the cold tap at that sink can run warm for a few seconds.
- Hot water and electricity together: use a grounded outlet and follow the maker's installation steps.
