Why it matters

The CITS-50 pairs a 1/2 HP cast iron primary with a PSC copper-wound motor and a battery backup, preassembled and preplumbed. Basement Watchdog states the primary moves 73 GPM (4,400 GPH) at 0 ft and 59 GPM (3,540 GPH) at 10 ft.

The backup controller monitors pump, power and battery around the clock, sounding an alarm and describing what to do. Add the CONNECT Wi-Fi module (sold separately) for text, email and app alerts. It works with AGM or wet-cell batteries, and two batteries in parallel double the runtime.

Who it's for, and who should skip it

Good fit if

  • Owners who want alerts
  • Finished basements
  • Replacing a tired primary

Look elsewhere if

  • Small pits
  • Owners who won't maintain a battery
  • Tight budgets

Pros and cons

Pros

  • Cast iron primary
  • 24/7 monitoring
  • Wi-Fi capable

Cons

  • Wi-Fi module extra
  • Battery extra
  • Higher price

Limitations to weigh

  • Battery backups need a separate 12 V deep-cycle battery unless one is included; check the battery's age every year.
  • Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
  • Maximum head is where flow drops to zero; at your lift the pump moves less than its maximum flow. Size it with the sizing calculator.
