What to Look for When Choosing the Little Giant Sump Pump

Choosing a sump pump requires some prior knowledge of how it works and what makes it desirable. You will find a bunch of things below that you need to consider before making the purchase.

Float Switch

Float switches activate sump pumps by detecting water levels. Little giant offers automatic water level detection with an integral diaphragm float switch. Its high and low water levels are adjustable.

You can opt for tethered or vertical float switches. A tethered switch enables the motor to cool off for longer after each cycle, unlike a vertical switch, which has more cycles. Mineral buildup can limit a vertical float’s efficacy, but it can operate inside a narrow sump. Only if your sump is wide enough, can a tethered float properly operate as it takes up some space?

Pressure Switch

A pressure switch checks the water’s pressure and turns on the pump accordingly. You can find some Little Giant pumps with maximum water pressure ratings. Unlike float switches, pressure switches do not have to face any obstruction as they are totally confined. But pressure switches cannot be adjusted for water levels.

Check Valve

A check valve is needed to ensure a one-way water flow. Otherwise, water would fall back into your sump’s basin after the pump turns off. For a new sump pump, even if it comes with a check valve, it is recommended to use a replacement. This is done because the flap of an existing check valve might be corroded by minerals from water.

Battery Backup System

Your house may not have power during a storm, but this is when you need your sump pump to work the most to prevent flooding. A battery-backup system could save the day.

Battery backup enables a different pump connected to the discharge pipe to operate- this means that you will get a working pump for hours when power is out. There are many options for battery backup in Little Giant products. You can set up the battery separately.

Alarm

A water level alarm warns when the water has reached a certain threshold, and it’s time for the pump to dive into action. This is essential for manual pumps but can be installed on automatic ones too. An alarm system for low battery indication is useful as well.

Size

The size of the product is important for a lot of people. Lack of space leads to the need for smaller sump pumps that can fit in narrow chambers. Luckily, there are many Little Giant options to choose from that are built to operate in tight spaces.

If you would like to shift the pump from time to time, you might want something portable- lighter than 20lbs. To replace your pump or its parts, you need to confirm that they are the same type and size.

Make sure that the discharge tubes are not less than 1.25″ in diameter on the inside because smaller tubes require more work from your pump. You want to measure the height of the lift to know the head pressure- 10-foot is standard. Measuring the pump’s floor area will give you an idea of how much water it holds.

Impeller

An impeller’s job is to create a low-pressure area at the center of the pipe and force water in from the pit. You have to have a good impeller. Make sure that it has no sign of wear or damage because a broken impeller means an ineffective pump.

Material is also important; choose a strong one with more corrosion and cavitation resistance, which best suits your budget.

Warranty

Always check the warranty before buying so that you can get help from the company within that period. Usually, most Little Giant sump pumps have a 2- or 3-year warranty. A longer warranty indicates the reliability of the product. Sometimes manufacturers give you a chance to increase it.

Build Quality and Design

You don’t want to buy another pump every 2 months, do you? This is why you have to get a high-quality product; one with the correct fittings that will save you from frequent hassle. Design is also important. For example, if you want to remove grey water, look for an effluent pump.

Sump pumps can be made of metal or thermoplastic or a grouping of plastic and steel. Metal is better. However, cast iron is a generally favorable option because it’s bulky.

It stays put and has superb resistance against rust. When it comes to filtration, if you need your pump to handle a chip of rock from time to time, you would want a special kind of impeller- but this will compromise the pump’s capacity.

There are pumps of submersible or pedestal base types. A pedestal one is easier to retain and cheaper too. Also, the waterproof housing of the motor is not required. The drawbacks are: it is noisy and prone to overheating during heavy operation as it cools by air instead of water. It is used for pumping above ground.

A submersible pump is to be situated at your sump’s bottom. It is pricier than a pedestal pump and requires good quality protective housing or there will be leaks. But its motor is effective, cools off quickly, and does not make half the noise of a pedestal pump.

Horsepower

Horsepower determines how fast a pump can transfer water. Little Giant sump pumps offer motors starting from ¼ HP. For a basement, you want one with 1/3 HP. If a pump has to move water to a greater distance, then it will need more horsepower. So, know how it is related to pumping ability for different lifts, usage, etc., and check the specification sheet to get the right horsepower.

Installation

You want to know the right procedures from the instruction manual before attempting to set up a sump pump. After placing and connecting the parts accordingly, inspect if any opening or bolt malfunctions or has leaks. It’s okay to call a plumber to install it for you in case of any confusion.
