Why it matters
The RL-SC50V is a 1/2 HP cast iron sump pump with a piggyback vertical float: it starts at 7.25 in of water and stops at 2.75 in. The float plugs in separately, so you can test or service it.
Red Lion rates it at 4,300 GPH at zero lift and 28 ft shutoff on 5.3 A, passing 3/8 in solids. It suits basins 15 in or wider and has a three-year warranty.
Who it's for, and who should skip it
Good fit if
- Narrow pits (15 in or more)
- Higher lifts
- Budget 1/2 HP
Look elsewhere if
- Sewage or toilet waste
- Draining pools or floors (a utility pump is cheaper)
- Homes that need a backup but have only one pump
Pros and cons
Pros
- Cast iron
- Piggyback float
- 28 ft shutoff
Cons
- 3-year warranty
- Leaves 2.75 in
- Plug-in float takes outlet space
Limitations to weigh
- 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.
- Fit a check valve on the discharge so water in the pipe doesn't fall back into the pit after each cycle.
- Plug it into its own grounded outlet; many makers warn against extension cords.
