Top 5 Best Backyard Sump Pump Reviews

1. Wayne CDU980E Sump Pump

WAYNE CDU980E 3/4 HP Submersible Cast Iron and Stainless Steel Sump Pump With Integrated Vertical Float Switch
9.7/10 Our Score

Besides coming from a prolific brand, the ¾ HP submersible Wayne CDU980E is an efficient workhorse that’s easier to use than contemporary products. If your backyard becomes a raging river, the Wayne CDU980E continues to deliver at a peak flow rate of 4,600 gallons/hour.

Its impressive features include a suction tube filter that ensures dirt won’t clog the impeller and prevent the device from functioning optimally. Water in your backyard is likely to contain debris from leaves, grasses, or dead animals. We consider it important to buy a pump with its own filter. The CDU980E’s stainless steel chassis and cast iron base combine to keep it sturdy.

This backyard sump pump removes as much water as possible, leaving you with a dry yard. It can pump water up to a 10 feet vertical distance at a sky-high flow rate.

The Wayne CDU980E is a twelve-pound yet heavy-duty beast that’s easy to use when you follow the manual. However, you might need professional help with installation.

If you want a machine to move torrents of water within minutes, the CDU980E is a wise investment with a five-year warranty.

What We Like
  • ¾-horsepower motor removes as much water as flows through most backyards
  • Strengthened polycarbonate impeller
  • The 4,600-gallon flow rate is higher than most other pumps on the market
  • The 5-year warranty is reassuring
What We Don’t
  • The float is a tad flimsy
  • Sometimes, the switch may not turn off
  • This is one pricey sump pump

2. Superior Pump 91250

Superior Pump 91250 1/4 HP Thermoplastic Utility Pump, Black
9.6/10 Our Score

This device is affordable for homeowners, so it’s a cheap way to move water off your backyard. At ¼ horsepower, the motor is less powerful than the Wayne CDU980E’s, but it can shoot 1,800 gallons/hour.

When pumping 10 feet vertically, this Superior Pump can lift 1,200 gallons per hour. We consider this to be a decent flow rate for a submersible pump in its price range. It’s a sturdy machine too, armed with screen filters that help keep debris from clogging your machine. There’s no need to worry about 1/8-inch solids such as gravel when using the 91250.

Everyone knows that the Superior Pump brand lasts long. The Superior 91250 ships with high-quality components. We quickly noticed the following features:

  • Electronically controlled split capacitors
  • Shaft seals with stainless steel jackets
  • Copper motor wingdings
  • Motor plate with double O-ring seals

Perhaps the biggest assurance with this device is the presence of a filter that keeps the impeller unclogged. Therefore, the machine works well for a long time before serious issues affect its performance.

The 91250 has a carrying handle with a 10-foot power cord enabling it to cover an expansive backyard. This backyard sump pump sports a thermoplastic construction to resist corrosion.

It’s an easy device to set up, and we think the one-year warranty is better than nothing.

What We Like
  • It’s budget friendly and gives you the most value for its price
  • The multiple hookups and discharge options allow for an easy setup
  • It’s simple to install
  • You’ll worry less about debris because of the screen filters
What We Don’t
  • The motor is a low-power engine, so you can’t expect too much
  • Some may argue that its one-year warranty could be longer

3. Wayne WSS30VN Sump Pump

Wayne WSS30VN Upgraded Combination 1/2 HP and 12-Volt Battery Back Up System , Black
9.6/10 Our Score

Here’s another Wayne that’s worthy of note. It’s essentially two backyard sump pumps in one: one pump you can connect to your home mains and a battery-powered backup that activates if a power outage occurs. With the Wayne WSS30VN, the only way for water in your backyard is out.

In terms of power, you have a machine that comfortably takes 5,100 gallons/hour out. It’s an excellent solution for moving water in large sump basins 16 inches or more in diameter.

This sump pump’s battery backup can only move 2,900 gallons per hour. At full charge, it can move around 10,000 gallons of water, keeping hope alive even in the heaviest downpour.

If you don’t enjoy the noise from other pumps, the WSS30VN is a noiseless beast. After learning about the million cycle tests on this product – a rare thing in the sump pump industry – it’s easy to see why the Wayne WSS30VN is good at what it does.

And YES, it doesn’t come cheap.

What We Like
  • The utter silence for such an efficient water-moving machine
  • The fallback battery option is an attractive feature
  • The flow rate on both machines is simply excellent
What We Don’t
  • Prepare to dig deep into your pockets to get this sump pump

4. Zoeller M53 Mighty-Mate

Zoeller M53 Mighty-mate Submersible Sump Pump, 1/3 Hp
9.7/10 Our Score

With a reputation in the sump pump industry bordering on reliability and longevity, Zoeller remains one of the most respected names around. The M53 Mighty Mate isn’t the most powerful unit money can buy. It’s not even the most efficient, but it’s great for typical situations.

We enjoyed deploying the automatic switch as it allowed us to “install and forget.” A powerful cast iron pump, the Zoeller M53 Mighty Mate sports a great design for durability and heat dissipation.

The 9-inch power cable has no disconnect and is shorter than most competitors. But if you don’t mind this (you might have a small backyard), then this machine is worth taking a look at.

What We Like
  • Automatic float activating switch looks good on this 1/3 HP pump
  • Powder coating protects epoxy fasteners
  • No need to worry about overheating
  • It moves large amounts of water quickly
What We Don’t
  • Reported issues with float switch malfunctioning
  • The pump occasionally gets faulty
  • It’s relatively noisy

5. Little Giant 5-ASP-LL 505350 1/3 HP Automatic Hydroponic Utility Pump

Little Giant 5-ASP-LL 505350 1/6 HP Automatic Hydroponic Utility Pump, 1200 GPH
9.2/10 Our Score

Backyards are prone to flooding, and Little Giant 5-ASP-LL 505350 is tailor-made for the continuous water-removal work they require.

Sporting a durable 1/3 horsepower shaded-pole motor that can resist damage, there is built-in overload protection to prevent accidental overheating and dying when it’s run around the clock. It can also run at peak performance without any parts getting burnt and needing replacement.

The Little Giant Automatic sump pump runs on a standard 115-volt plugin, making it easy to plug it into an extension cord if you need more length.

If you like nothing but durable stuff, this backyard sump pump has upper and lower sintered sleeve bearings besides a cast iron housing with epoxy coating.

The housing will keep out corrosion, rust, wear, and tear while your pump delivers maximum service year after year. All of this contributes to extending the lifespan of the device.

With the 5-ASP-LL 505350, you don’t just get a trusty machine. You get a device that’s really sturdy when it’s delivering its optimal 1,200 gallons/hour capacity. This is down to a broad base that keeps it from toppling over. 

We also like the simple handle at the top that makes the pump easy to carry around your backyard.

What We Like
  • This machine can work continuously
  • It has a shaded pole motor
  • The built-in overload protection is an excellent feature
What We Don’t
  • The edges corrode easily
  • The Little Giant isn’t quite a good match for large projects
  • The handle is thin

Final Thoughts

A sump pump can be a real life saver, especially you live in flood-prone areas.

But whether you have to get one right now or not, you’ll eventually need a sump pump for your backyard.

It’s one of those seemingly dull purchases that can save you a whole load of trouble later down the road.
