Multiquip YELLSUB 1/4 HP Submersible Electric Utility Dewatering Pump

The Multiquip YELLSUB 1/4 HP electric submersible utility pump removes, transfers, and evacuates standing water from flooded basements, swimming pools, low-slope flat roofs, livestock tanks, and residential drainage sumps. Powered by an energy-efficient 115V 2.5 Amp single-phase electric motor delivering up to 33 gallons per minute (GPM) with a 15-foot total head lift, this lightweight 6-pound dewatering pump draws standing liquid down to a shallow 1/8-inch surface level. Outfitted with a corrosion-proof engineered composite housing, a direct-drive thermoplastic impeller with stainless steel hardware, internal thermal overload protection, and an included garden hose adapter, it provides property managers, plumbing contractors, and homeowners with rapid, plug-and-play emergency drainage.

Best Used For:

  • Emergency Basement and Crawlspace Dewatering: Evacuating ground seepage, plumbing overflow puddles, and sump pit accumulations down to 1/8 inch off concrete slab floors.
  • Flat Commercial Roof and Deck Drainage: Pumping off pooled rainwater from flat membrane roofs, patio depressions, and building foundation trenches before structural leaks occur.
  • Residential Pool, Fountain, and Tank Transfer: Emptying swimming pool winter covers, hot tubs, decorative garden ponds, livestock watering troughs, and water storage containers.

Key Performance & Safety Features

  • High-Volume 33 GPM Flow Capacity: Rapidly discharges floodwater up to 1,980 gallons per hour to quickly clear submerged living spaces and equipment rooms.
  • Low-Suction 1/8-Inch Floor Clearance: Bottom suction intake skims water levels down to a bare 0.125 inches to minimize final sponge cleanup time.
  • Corrosion-Proof Engineered Polymer Housing: Single-piece composite shell resists rust, chemical scaling, impact damage, and operational heat buildup.
  • Internal Thermal Overload Protection: Built-in thermal sensor automatically cuts electrical power if dry-running or motor overheating occurs, preventing burnout.
  • Dual Mechanical Shaft Seals: Double-sealed barrier wall prevents pressurized liquid from migrating into the copper-wound motor housing.
  • Included Garden Hose Thread Adapter: Converts the standard 1-1/4" NPT discharge outlet directly to a 3/4" garden hose thread for instant residential deployment.
