Why it matters
The PM01 is a small submersible pump with a built-in level sensor that switches it on and off. It sits in a tray or tank and lifts water about 3 ft, enough to empty a dehumidifier tank into a nearby sink or drain.
Its bottom-suction design pulls water down to about 1 in, and it waits a few seconds after the level drops before stopping.
Who it's for, and who should skip it
Good fit if
- Dehumidifiers
- Air coolers
- Short lifts into a nearby sink
Look elsewhere if
- Furnaces and central AC
- Any lift over 3 ft
- Unattended appliances that need an overflow switch
Pros and cons
Pros
- Automatic level sensor
- Very small
- Inexpensive
Cons
- 3 ft lift only
- No overflow safety switch
- Lesser-known brand
Limitations to weigh
- Clean the tank, float and check valve every six months or so; algae and slime cause most condensate pump failures.
- With only about 3 ft of lift, it can't reach a drain much higher than the appliance.
