Everbilt 1/3 HP (HDPS33W) Submersible Sump Pump with Tethered Float, 36 GPM @10 ft, 1-1/2″ FNPT discharge, 3/8″ solids handling, PSC motor, aluminum motor housing, CSA listed

Condition: New — factory sealed retail box. Includes pump and 1-1/2″ FNPT discharge port (fittings not included). No prior use or installation.

Overview

The Everbilt HDPS33W is a reliable 1/3 HP submersible sump pump engineered for residential basins with an automatic tethered float. Its efficient PSC (permanent-split capacitor) motor sits in an aluminum motor housing for superior heat dissipation and long service life. The semi-open thermoplastic impeller passes 3/8 in. spherical solids, making it a strong choice for routine groundwater removal. With 36 GPM (≈2200 GPH) at 10 ft of vertical lift and a shutoff head of 23–25 ft, it’s sized right for most single-family basement pits and crawlspaces.

Features

• Automatic operation via tethered float switch (On ~11.8″, Off ~3.94″)
• PSC, oil-filled motor with thermal overload protection for durability
• Aluminum motor housing → efficient cooling, continuous duty capable
• 3/8″ solids handling using a semi-open thermoplastic impeller
• Quiet, fully submersible design
• 1-1/2″ FNPT discharge (standard sump size) for low friction loss
• Compact footprint fits standard pits; requires ≥18″ diameter basin for tether swing
• CSA certified; designed for residential sump applications

Specifications

• Flow @ 10 ft head: 36–36.7 GPM (≈2200 GPH)
• Flow @ 15 ft head: ≈33 GPM
• Max/Vertical Lift (shutoff): 23–25 ft (≈9.96 PSI)
• Solids Handling: 3/8 in. spherical
• Discharge Port: 1-1/2″ FNPT (fittings not included)
• Cord Length: 8.25 ft
• Switch Type: Tethered float (On ≈ 11.81″, Off ≈ 3.94″)
• Operating Temp: 35–100 °F
• Housing: Aluminum motor housing with thermoplastic volute/impeller
• Dimensions (approx.): 6.3″ D × 8.27″ W × 10.63″ H
• Weight: 8.49 lb (ship wt. ~9.45 lb)
• Amperage: listing shows 15 A (use 15 A minimum branch circuit; check motor nameplate for running amps)
• Certifications: CSA (and UL-compliant components where noted)
• Warranty: 1-year limited (from manufacturer)

Pro tip: For maximum flow, plumb with 1-1/2″ PVC and long-sweep fittings. Reducing to garden hose will dramatically decrease performance.

Applications / Spheres of Application

• Basement & crawlspace sump pits (primary pump)
• Groundwater & storm infiltration removal from standard residential basins
• Garage, utility room, and light pit dewatering (clean/gray water only)
• Retrofit/upgrade from older 1/3 HP pedestal or submersible pumps
• Battery-backup pairings (this is the primary AC pump; pair with DC backup where required)

Pros & Cons

Pros

• High output for class: 36 GPM @10 ft covers most home runs
• Efficient PSC motor with cooler-running aluminum housing
• Automatic tethered float—simple, proven design
• 3/8″ solids tolerance reduces clogging vs. closed impellers

Cons

• Tethered float requires ≥18″ basin; not ideal for slim pits (use vertical float model in tight basins)
• 8.25 ft cord may need a GFCI-protected receptacle closer to the pit
• Not designed for sewage, effluent with fibers, hydrocarbons, or hot water

Installation Notes & Best Practices

• Use a 1-1/2″ check valve (spring or flapper) within 10–15″ of the pump discharge to prevent backflow.
• Plumb in 1-1/2″ Schedule 40 PVC with a union above the check valve for service.
• Support vertical discharge to reduce vibration and stress on the volute.
• Verify float travel is unobstructed (pipes, pit walls, cords) to avoid short-cycling.
• Protect the circuit with a GFCI receptacle; keep connection above floor level.
• Test quarterly: fill pit with water until the float rises and pump cycles; confirm check valve seals on shutdown.
• If local code requires, add a high-water alarm and battery backup system.

• High-water alarm and optional battery backup (12 V DC pump)
• Condensation management tie-ins from dehumidifiers/AC coils (where permitted)

Included

• Everbilt HDPS33W 1/3 HP submersible sump pump (sealed)
• Factory paperwork (warranty/quick start) inside the box

Not Included

• Check valve, discharge piping/fittings, high-water alarm, battery backup, pit/basin, or installation labor

Common Requests:

1. “Is my 18″ basin large enough for the tether to swing freely?”
2. “What check valve and union do you recommend for 1-1/2″ PVC?”
3. “How much flow will I lose if I reduce to 1-1/4″ or garden hose?”
4. “Can I use this with a battery backup system and high-water alarm?”
5. “What maintenance keeps performance high (screen cleaning, float test schedule)?”
