Top 10 Sump Pumps with Tether Floats
for December 2023

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.

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 Superior Pump 92341 1/3 HP Cast Iron Submersible Sump Pump with Vertical Float Switch has all of the features we look for in a pump, plus a few extras. It's pretty rugged, with cast iron construction that gives it a longer life than plastic pumps, and it's built to last. It's also heavy enough (

The Superior Pump 1/2-horsepower cast iron sump pump with tethered float switch is a high-capacity pump that can move water up to 25' of vertical height. It has a 1-1/2-inch NPT discharge, so it pumps more water than other pumps of its class. The pump is powered by 1-1/2 HP, 115V motor and handles solids up to 1-1/2 inches. The tethered float switch automatically turns the pump on/off when it detects water, so the pump won't drain dry. The pump has 10-foot cord, and it has a 4-1/2-inch diameter inlet, a 3-1/2-inch diameter discharge, a 4-1/2-inch diameter outlet, and a 5-1/2-inch diameter sump.

The RainBro CSE050 is a heavy-duty sump pump that pumps out water fast. It has a 1/2 hp motor, which pumps out 6000 gal. of water per hour. The pump can lift water up to 27ft. of vertical height, and will handle up to 2in. solid. The CSE050 is easy to set up and has a durable cast iron construction. The pump is fully automatic, and has a float switch that cuts off the pump when it is full. The float switch cable is adjustable, so the pump will turn off automatically when the float is submerged. The float switch cable is 10 ft. long, and the pump has a 10 ft. piggy back tether. The pump has 4 flood-proof seals, so it will keep working even in a flooded basement. The pump is easy to operate, and it has a 1 year warranty.

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 RP50's 1/2 hp motor is designed to handle solids up to 2 in. in diameter. The pump is easy to install and, thanks to a heavy duty discharge hose, it can handle a variety of applications, including whole house sewage systems, grey water systems, and stormwater systems. The pump is also easy to set up, and it's equipped with a tether float switch, which will automatically turn the pump off if the float sensor is triggered. The RP50 comes with everything you need, including a 3.5 in. discharge hose, a 3 in. drain hose, a 4 in. suction hose, 4 in. suction hose with 90 degree elbow, 3 in. check valve, and an installation manual. The pump also comes with a 1-year warranty, which is one of the best warranties we've seen on a sewage pump.

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.

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' (
