A sump pump is an invaluable piece of home equipment, draining water from your basement, crawl space or utility room. A sump pump with tether float is a sump pump with a float that automatically shuts off the sump pump when water passes a certain level. The float is attached to a tether, which is connected to a cord that provides a power source.

MOOZ Themes Reviews tests sump pumps with tether floats for performance, including how quickly the sump pump drains water, how it handles water, and how well it works under heavy loads. We also evaluate how easy the sump pump is to install, and how easy it is for maintenance.

THE BASEMENT WATCHDOG Model 1/2 SP-50T HP 3

by Glentronics Inc

1/2 HP, 5.5-Amp energy efficient permanent split-capacitor (PSC) motor provides optimal GPH output

The Basement Watchdog SP-50T 1/2 HP 3,900 GPH at 0 ft and 3,100 GPH at 10 ft Submersible Sump Pump with Tether Float Switch is a sturdy, well-built pump that's ideal for draining and refilling sump pits. It pumps plenty of water, and the pump's float switch is very sensitive, so it's very easy to empty a sump pit. The powerful motor runs quietly, and it has ball bearings on the shaft, so it's extremely quiet. The pump's 10 ft power cord is long enough to reach most sump pits, and the pump also includes two 3/8 in. tubing adapters and a 3/8 in. x 3/8 in. check valve. The pump's non-corroding, thermoplastic construction also makes it durable. The Basement Watchdog SP-50T 1/2 HP 3,900 GPH at 0 ft and 3,100 GPH at 10 ft Submersible Sump Pump with Tether Float Switch is a good choice for a sump pit pump, and it's even well-priced for what you get.

Float Switch for Sump Pump -100-Foot Water Level Sensor with Honeywell Microswitch and Adjustable Tether Length for Ground Water Bilge Pump and Water Tank – Non-Corrosive PP Casing, Rated to 13 Amps

Sump Alarm Float Switch for Sump Pump -100-Foot Water Level Sensor with Honeywell Microswitch and Tether Adjustable Length for Ground Water Bilge Pump and Water Tank – Non-Corrosive PP Casing

by Sump Alarm, Inc.

ADJUSTABLE TETHER of its 100-foot PVC jacketed cable makes our automatic bilge switch suitable for an array of applications. Eliminate complex automation with this sump pump replacement float switch.

The Water Boss float switch is a high-quality, low-cost choice that's ideal for most bilge pumps and larger water tanks. It's easy to install, and it comes with an adjustable tether, so it's versatile enough to work with 1/4- or 1/2-inch hoses. The float switch measures only 3.5 inches tall, and it's small enough to fit where other sump pump float switches would get in the way. Our only complaint is that it can take some time to calibrate the float switch, since the tether is adjustable. The Water Boss float switch is accurate but sensitive, so it's best used for pumps that keep the water level below 13 inches.

The Wayne RP50 is a high-quality, heavy-duty sewage pump. It's powerful, quiet, and will last for years, making it a great budget option for homeowners with basement or below-grade sewage systems, as well as for larger properties in suburbs or rural areas.

The Superior Pump 92005 25' Tethered Float Switch is one of our favorite submersible sump pumps, and it's easy to see why. It's powerful enough to work for several hours, and it does a good job of maintaining a clean sump. The switch itself is reliable and works well, and it's easy to install. The power cord is a little longer than most, which is a nice feature. The power cord has a piggyback plug, which makes it easy to plug the pump into a standard extension cord if you don't have a 25-foot cord. The extension cord also comes in handy if you want to move the pump around, which is especially helpful if you're using a submersible pump for water filtration. The switch has manual on/off and an auto-shutoff after 20 minutes, which is enough for everyday use. The auto-shutoff feature works well, but we'd still recommend turning it on manually from time to time. The switch has a 25-foot cord, so it's long enough to have the pump float away from the sump if necessary. The downside to the switch is that it doesn't come with a float switch. If you prefer a float switch, we recommend the Andersen 25' Float Switch.

RainBro 3/4 HP Cast iron submersible sewage pump with 10 ft. piggy back tether float switch, Model# CSE075

RainBro 3/4 HP Cast iron submersible sewage pump 10 with ft. piggy back tether float switch

by RainBro Pumps

DURABLE - Rugged cast iron construction with 10' power cord length.

The RainBro CSE075 is an easy-to-install, submersible sewage pump for aquariums and ponds. It can handle sewage and wastewater, as well as water up to 2 inches in diameter. RainBro sells a different model, the CSE072, that has its own float switch, but we prefer this one because it comes with a tether float switch, which makes it easier to set up. The pump is also easy to install: just hang it from the included 10-foot cord and connect it to your aquarium's Filter's Power Cord. The pump is fairly noisy, but it's loud enough to be heard over splashing, and it's relatively compact and portable, so you can easily move it from tank to tank. The CSE075's 3/4-hp motor is powerful enough to lift water up to 29' (
