Little Giant 506160 51979 Sump Pump Review

So our first one for this little giant sump pump review will be the 506160 51979 model. It has worked wonderfully for the customers. That’s why we think you would be satisfied with this pump too.

The pump can be utilized for residential and light commercial uses. It has a cast iron body accompanied by a polycarbonate cover and polypropylene volute-base. This unique construction design indicates durability and reliability that can handle water emergencies smoothly.

Cast iron is really amazing at heat-dissipating and keeping the pump motor cooler. It transfers heat from the motor to the water around the pump. Plus the anti-corrosion elements in the pump help to guard against any water damage that can reduce its efficiency.

The clever use of polycarbonate cover helps to lower the price and weight. A light sump pump is always more preferable than a heavy one. It is easier to carry and repair. Apart from these core benefits, polycarbonate also provides great strength to the pump. It is 250 times stronger than glass and close to impossible to break.

The flow rate is 46 GPM and the maximum pump height is 18-foot. This 1/3 HP pump-motor is powerful and can get rid of accumulated water pretty quickly. Little Giant also offers you 2 years warranty for this pump.

Another amazing advantage of this sump pump is that you won’t have to worry about it running dry. This pump is specifically made for such purposes. Customers have reported that the pump doesn’t lose efficiency even if you only turn on it a few times a year. As long as it gets electricity, you can sleep without any worry.

Moreover, the pump has 4.4 stars out of 5 on Amazon. The manufacturers always encourage you to report any issue through their phone service. And customers have found this service quite helpful.

  • All the parts are pre-assembled for your ease of installation.
  • It comes with an 8-foot long power cord.
  • It is a quiet and durable pump.
  • The pump also features thermal protection to prevent any accidental failures due to overheating.
  • The cast iron pump housing with polycarbonate cover is meant to last decades without any wear and tear.

Cons

Little Giant GIDDS-521252 12393 Automatic Sump Pump Review

This GIDDS-521252 12393 pump model from Little Giant would be our top pick for today’s article. The power and price both remain in the midrange. As a result, we can recommend it to any homeowner looking for an effective pump within the average price range.

This little workhorse is made of solid cast-iron with powdered epoxy coating on the outer layer. We all know the benefits of using cast-iron as the pump housing material. Your pump gets to work more hours without showing hot spots or red spots. A cooler pump also means a durable pump. Most of the pump failures are caused by overheating during excessive operation. But luckily, this pump has the potential to overcome such severe issues.

Also, the powdered epoxy coating adds one more layer of water protection. Since the pump is submerged in water 24×7, extra caution is a must. This coating has non-corrosive properties to protect against corrosion or rust.

The 1/3 HP pump has a flow rate of 2760 GPH. This capacity is enough for most of the houses with the average water levels. It is outfitted with an automatic pressure switch that turns on at 7-10 inches water height and turns off at 2 inches water height.

Moreover, it has got 4.5 stars out of 5 on Amazon. Customers are highly satisfied with their performance and longevity. It helped them to keep their house safe during hurricanes or heavy rainfall. It surely deserves to be on top of your favorite list.

Here is a piece of advice. Make sure to install a good quality check valve. Check valves can stop water from changing direction in the discharge pipe. Thus, water doesn’t flow back into the sump pit again as soon as the pump stops. Also, install a decent filtration system so that the pump doesn’t have to deal with mud.

Pros

  • It comes with a 2-year limited warranty.
  • The construction material is durable and strong.
  • 1/3 HP pump-motor is very reliable during tough times.
  • The price tag is also reasonable.
  • You can use this pump for various commercial, industrial, or residential applications.
  • You won’t have to open it frequently for maintenance since it is always lubricated.

Cons

  • Though it is a reliable pump, some customers have complained that it loses efficiency after some time.
  • You can’t drain a flooded yard with this pump since it features a pressure switch.

Little Giant LG5MSP 1/6 HP Submersible Pump Review

The next one is different from the previous two little giant sump pumps. This LG5MSP 1/6 HP Submersible Pump can accomplish various tasks with ease.

Unlike the previous two pumps, the construction material for this pump is cast aluminum. If you don’t know already cast aluminum is famous for its lighter weight. Also, it provides corrosion-resistance and higher thermal conductivity. As a result, it can transfer heat pretty quickly into the water. The cleaning procedure also gets easier with aluminum pump housing.

As the name suggests, it is meant to handle hydroponic activities. It means that the pump stays inside a hydroponic tank or reservoir that uses pipes to transfer water from one place to another systematically. Submersible pumps like this one can handle such tasks on a small-scale. If you are a hobbyist, this pump can surely make you happy. But for a large-scale operation, people mostly install an inline pump.

The bottom intake impeller design with pre-screen makes sure that no debris or pebbles can interfere with the operation. Most of the time, these uninvited intruders get stuck into the rotating part and hamper the performance. As a result, the temperature starts to rise. But thankfully, this little beast can overcome such obstacles without making you worry.

It is permanently lubricated and provides stainless steel shafts. Stainless steel is the most desirable material for the rotor shafts of a pump. Only high-end pumps use this material to ensure superior quality. The flow rate of this pump is 1/6 HP pump is 1200 GPH at 1′.

It has got 4.3 stars out of 5 on Amazon. Some customers have reported that it has worked efficiently for them for over a decade.

Pros

  • It comes with a garden hose adapter
  • It is also great for hydroponic activities that don’t require more power than 1200 GPH.
  • It is a submersible pump and produces less noise than its pedestal counterparts.
  • The impeller is manufactured to avoid debris and small stones successfully.
  • It can fit and operate into small sump pit spaces without any trouble.
  • The phone service is quite helpful for the buyers.

Cons

  • If your hydroponic application requires more than 1200 GPH, then this pump will be less efficient than an inline pump.
  • Some customers have complained about oil leakage.

Little Giant 506274 6 Series Submersible Sump Pump Review

This 506274 6 Series Submersible Sump Pump is an excellent solution for difficult water issues. If you want something small in size but big in output, then no need to look further. This 1/3 HP shaded pole motor comes with overload protection. The sensor inside the pump can detect the rise in temperature precisely.

When the temperature exceeds a pre-determined level, those sensors send a signal to the pump and halt the operation immediately. Though it can create a sudden obstacle, the long-run consequence of this system is great. Your pump gets saved from severe damages and can run longer with efficiency.

The pump housing material used here is heavy-duty cast-iron with an upper layer of powdered epoxy. Since it is a submersible pump, this upper layer will form an extra defense to protect against water.

Epoxy is made by polymerizing a resin and hardener in the presence of a specified catalyst. This process enables it to possess properties such as thermal insulation, higher cleaning ability, better aesthetic look, and heat conductivity.

If only a drop of water can get into the inner chamber of the pump, the whole pump would start to malfunction and will eventually stop working. That’s why manufacturers choose a material that doesn’t allow even a single drop of water to enter.

The pump is well-designed with sintered sleeve bearings. Sleeve bearings are better than ball bearings in many aspects. It can provide infinite radial thrust capacity and can manage high-speed activity. That means if you require a pump that doesn’t get worn out easily, this is the way to go.

Also, sleeve bearings help the pump to work quieter. That’s why even if the pump is installed close to your bedroom, you can still have a good sleep without any disturbing noises. You can use it in your swimming pool too.

Pros

  • It comes with overload protection to save it from unwanted accidents.
  • The price range is reasonable.
  • It offers you two years manufacturer’s warranty.
  • You also get a 3/4 inches garden hose adapter with it.
  • The cast iron construction is designed to last.
  • You can use it for commercial, industrial, or home applications.

Cons

  • This model doesn’t provide you an automatic switch. It means that the pump will run as long as it is plugged in.

Little Giant 508158 Automatic Sump Pump Review

Our last but not the least pump for today’s article is the 508158 Automatic Sump Pump. As the name suggests it is an automatic pump. This pump is basically designed to move a huge amount of water. That means it is perfect to use for cleaning the pool or pond. Now let’s have a closer look at this amazing pump.

This automatic pump relies on an advanced pressure switch for activation. The turn-on point is 7 to 10 inches and the turn off point is 1 to 4 inches.

When the water keeps rising into the sump pit due to extreme rainfall, the pressure also increases. As soon as the water crosses the exact points, the switch triggers the pump and signals to start working. Then the pump runs until the water falls. Automatic pumps were invented to ensure the homeowner’s peace of mind during difficult times. Now, you don’t have to be present in the basement every time the weather is bad.

The construction material is rugged cast- iron with a polycarbonate cover and polypropylene volute-base. We all know the reason for using cast-iron and how you benefit from this. As for the polycarbonate cover, it offers you great value too. It is durable and lightweight at the same time. Plus it has the elements to resist abrasion, corrosion, and impact. So it can take more abuse of rocks, debris, and water without showing any sign of wear and tear.

Moreover, the polypropylene used in the volute base is semi-rigid, has good heat resistance and chemical resistance. Such materials have enough strength and stiffness to support the pump. But they are low in cost and weight. This unique combination makes them qualified to be used in this high-end submersible pump.

The pump motor has a capacity of 4/10HP. Though it is not the best in the market, considering its other benefits we definitely recommend this to you.

Pros

  • Customers highly praise the phone service. It really helps them to fix the issue.
  • The pump can be used for residential and light commercial dewatering applications.
  • It comes with a long 25-foot power cord.
  • The 45 GPM flow rate is also satisfactory.
  • The pump motor is 24×7 lubricated with oil since it is oil-filled.
  • It is also outfitted with thermal protection to protect against overheat.

Cons

  • The pressure switch is not adjustable according to your needs.
  • The pump may lose efficiency after the warranty period.

Now, if we compare the GIDDS-521252 12393 and the 506160 51979, the former has better reviews and features. But the price and basic features like motor power are pretty much the same for both of them.

If you are looking for something that can complete various tasks and has more power and strength, then the LG5MSP 1/6 HP hydroponic pump is your pick.

The next two pumps: the 508158 Automatic Sump Pump and the 506274 6 Series Submersible Sump Pump both can be used for cleaning water in the pool. But the latter one is superior in power. It features a 4/10 HP pump-motor while the previous one features a 1/3 HP one. So if you want more strength and a higher discharge flow rate, go for the 506274 6 Series Submersible Sump Pump.
