A.k.a. the best 1 hp sump pump for basement floods

Let me be clear: this is NOT a recommendation for a 1 hp sump pump that you will use in a wall-mounted sump basin, to pump water that is exiting a foundation wall.

Nope.

If you need help with that, visit this post instead:

Well pump pit designs? DIY water well installation? This is not the article for you.

This is the article for you if you are looking for a pressure-pumped submersible well pump to pull clean water out of any domestic waterwell (with a waterline that has been drilled/installed, as opposed to a dug well).

You want a pure water well pump solution, with absolutely no connection to the sewage pipeline? This is the article for you.

A 1 hp sump pump can also be used in your main sump basin, to keep it clean and flowing (I have done exactly that for more than ten years), but that is a surprisingly uncommon use-case scenario (most people use a pressure-pumped well pump to enter their home’s pressurized water distribution system, instead).

Our rating: 10 / 10

Pros:

  • Environmentally-friendly
  • Durable and long-lasting
  • Affordable little giant sump pump

Cons:

  • For continuous use
  • Motor overheats

At first glance, this little giant sump pump seems to have it all. The Little Giant WE20G05P4-21 is cheap, durable, and has a small form factor for easy storage. However, if you look closely, you might find that this little giant sump pump has its flaws.

The Little Giant WE20G05 Pump is supposed to be able to pump out 20-gallons-per-minute (GPM), but the pump only provides 18 GPM. Also, the pump is rated up to 125 feet deep, but users claim it only pumps out about 65 feet deep. The motor gets noticeably hot when you operate the pump for less than five minutes, which can be rather alarming and lead to a potentially dangerous situation.

The Little Giant WE20-G05P4-21 does have some drawbacks when it comes to maintenance. The Little Giant company recommends only using deionized water, and that is one of the leading causes of a lime buildup in the tank. The tank and motor portion will need to be cleaned periodically because of the lime buildup, which can be a difficult task.

Frequently Asked Questions (FAQ)

What is the most reliable sump pump?

Sump pumps are actually very reliable, but only if you maintain them. Sump pumps work by placing an electric motor in a watertight outer case. This allows the water to enter the sump pump and then float through hoses to the pump in the sump basin. If a pump fails and quits working, then it will stop draining and you will need to replace it.

Sump pumps, when maintained, are the most reliable pumps available. If you service the pump and the drain, tube, and pit on a regular basis (every 1-3 years), then you won’t have any issues. However, if you don’t, then they can fail.

Is a bigger sump pump better?

Deciding what size pump to get mostly depends upon how much water can be accessed. If you live in a basement and have a lot of water coming in from the land around your home, then you probably don’t need just a small sump pump. You need something bigger. However, if you have a particularly small area of water, like one that collects from the rain, then a small sump pump will do.

Basically, sump pumps go up in power output, not size. This means that even a small sump pump can be bigger than a medium sump pump. We recommend getting the biggest sump pump that will fit. That way, you always have extra wiggle room in case of an emergency.

Are Barracuda sump pumps any good?

The Barracuda line of sump pumps from Little Giant are highly rated and frequently a popular choice. Make sure to have a read through a few of the higher rated reviews to get a feel for the quality for yourself.

Just to sum up the general opinion of a lot of buyers, these pumps are seen as being tough, durable, and yet reliable. Wattage varies by model, but all in the Barracuda line pump around 2000 GPH (Gallons Per Hour).

If you have the space, give them a look.

What is the quietest sump pump on the market?

The pumps described above are all great choices if you are on a budget, but all of the models above can be loud at their maximum output rating. However, if you are willing to take a few steps up in price (a 2-3x increase on some models), you can get one with a truly remarkable sound level.

The Little Giant Guardian Series is in our opinion, the quietest sump pump on the market. Now it's true that this is a model that fits those with a deeper pocket book. But if you are willing to spend money twice as much as the pumps above, you can get one that keeps a very low profile. This is especially important if you live in an area that is noise sensitive; you might not want to dig a hole to bury a loud pump.

Remember that many homeowners policies now require above ground protection for sump pumps, so if you are replacing your pump anyway, then this can be a good idea.

Conclusion

These pumps are small in size, but big in performance. It doesn’t require any venting, so you can use it in homes with limited space. It comes with a 1-year warranty and features a durable aluminum frame that can last for long. The Little Giant sump pump is easy to install and comes with a manometer, so you can easily gauge the water level.
