Red Lion RL-SC50T — 1/2 HP Cast-Iron Sump Pump with Tether Float
The Red Lion RL-SC50T is a rugged cast-iron sump pump built for dependable residential drainage. Its tethered float switch is ideal for larger pits, allowing longer run times and fewer starts per hour to reduce wear. Proven RL-SC Series hydraulics move up to 3200 GPH to help protect basements and crawlspaces from rising water.
Key Features & Benefits
- Tether float switch — best for larger pits; promotes longer cycles and fewer starts.
- 1/2 HP motor for strong residential sump performance.
- Durable cast-iron housing for quiet operation and long life.
- Up to 3200 GPH (53 GPM) for fast, effective water removal.
- Corrosion-resistant impeller engineered for efficiency and reliability.
Applications
- Basement and crawlspace sump systems
- General residential drainage
- Larger pits where longer pump cycles are preferred

Model Comparison
| Model | Float Type | Best For | Buyer Recommendation |
|---|---|---|---|
| RL-SC50V | Vertical Float | Small / narrow pits | Choose when space is tight and you want precise on/off levels |
| RL-SC50T | Tether Float | Larger pits | Choose for longer cycles and fewer starts to reduce wear |
Common Questions
Q: Why choose a tether float over a vertical float?
A: Tether floats need a larger pit but allow longer cycles and fewer starts, which can extend pump life.
Q: What discharge size does it use?
A: 1-1/2" FNPT standard sump discharge.
Q: Is the pump automatic?
A: Yes — the tether float provides automatic on/off operation.
Q: What is the shutoff head?
A: 20 ft total dynamic head (TDH).
The RL-SC50T is the right choice for larger sump pits where longer, gentler pump cycles help reduce wear while moving serious water.
