Overview

Everbilt 1/2 HP Cast Iron Submersible Sump Pump with Vertical Float Switch (Model HDS50)

The Everbilt 1/2 HP Cast Iron Submersible Sump Pump (Model HDS50) is the benchmark standard for residential flood protection and basement dewatering. Built with heavy-duty cast iron housing and pump base, the heavy iron casing acts as a massive thermal heat sink, rapidly dissipating operating motor heat to ensure exceptional longevity during prolonged high-volume storms. Driven by an energy-efficient 1/2 HP Permanent Split Capacitor (PSC) motor with built-in automatic thermal overload protection, the HDS50 pumps an impressive 5,100 gallons per hour at zero feet of lift, and 3,780 gallons per hour at a standard 10-foot residential basement head height. Its engineered vortex non-clogging cast iron impeller readily passes spherical solids up to 1/2-inch in diameter without jamming. Designed specifically for tight or standard sump pits, its precision vertical magnetic float switch operates smoothly in basins as narrow as 10 inches in diameter. Featuring an epoxy powder-coated finish for rust resistance, stainless steel fasteners, and a 10-foot SJTW grounded power cord, the Everbilt HDS50 delivers rock-solid, quiet performance you can trust.

Heavy Class 30 Cast Iron Body Rugged cast iron motor housing and volute dissipate heat rapidly, ensuring continuous heavy-storm dewatering without motor overheating.
High-Efficiency 5,100 GPH Flow Moves up to 5,100 GPH at 0 ft and 3,780 GPH at 10 ft vertical lift with 26-foot maximum shut-off head.
Space-Saving Vertical Float Switch Vertical switch mechanism operates without snagging on pit walls or discharge pipes; fits in basins 10" or larger.
1/2-Inch Solids-Handling Vortex Impeller Heavy cast iron vortex impeller passes 1/2-inch debris and silt without binding or loss of hydraulic pressure.
Epoxy Powder-Coated Corrosion Shield Double-coat epoxy protects against aggressive groundwater, corrosive minerals, and rust for years of continuous submerged duty.

Runs whole house including 4-ton AC without flinching

Ordered the Everbilt 1/2 HP Cast Iron Submersible Sump Pump with Vertical Float Switch (Model HDS50) after getting tired of sitting in the dark during Gulf storms. Freight delivery arrived on a liftgate truck right onto my concrete driveway. Hooked it into our manual transfer switch with a 50A cord and ran our central 4-ton AC, two refrigerators, well pump, and all household lights. Electric start fired right up on propane.

Clean freight delivery and great build quality

Driver called me 24 hours ahead of time to coordinate delivery. Unit was bolted onto a heavy pallet and wrapped securely. Added oil, connected a 100-lb propane tank, and pushed the start button. Purrs like a kitten and the digital meter makes monitoring voltage and hours simple. Couldn't ask for a better machine at this price point.

Fuel versatility is a complete lifesaver

The tri-fuel capability was the main selling point for me. Being able to connect directly to our residential natural gas line means no more storing 50 gallons of stale gasoline in the garage. Build quality is solid industrial grade and the frame feels bulletproof.

Remote start key fob works from inside the house

Tested the wireless remote start from about 80 feet away through the back patio door—started immediately. It is surprisingly quiet for an engine of this displacement. Very impressed with the packaging and complete hardware kit included.

Questions and answers

Can’t find what you need? Send us a message and we’ll get back to you.

Does this pump require a weep hole in the discharge pipe?

Yes. Drill a 3/16-inch weep (relief) hole in the discharge PVC pipe, approximately 1 to 2 inches above the pump discharge outlet and below the check valve, angled downward to prevent airlocks.

Can this pump handle small stones or gravel?

The vortex impeller is designed to pass solids and debris up to 1/2-inch in diameter without clogging, making it much more durable than standard thermoplastic utility pumps.

What size sump pit does it fit?

Because it utilizes a space-saving vertical float switch rather than a tethered float, it operates reliably in compact sump pits down to 10 inches in diameter.

How quiet is the pump during operation?

Because of the heavy cast iron body and water immersion, motor hum and vibration are almost entirely silenced. You will typically only hear the quiet click of the check valve.

Can it run continuously during severe rainstorms?

Yes. The oil-filled cast iron motor housing quickly transfers motor heat to the surrounding sump water, allowing it to cycle continuously through extended severe rainfall events.

What is the warranty and shipping policy?

This product includes free residential delivery from our Dallas warehouse, a 30-day hassle-free return window, and a 3-year limited warranty.

How does delivery work?

Delivery is free to residential addresses. Orders ship from our Dallas, TX warehouse, and larger items arrive by freight with a liftgate drop at your curb or driveway. You get a tracking number by email as soon as the carrier picks up your order.
