Buying Guide – How to Pick the Best Sump Pump for Crawl Space?

Do you think all sump pumps available in the market come with all the premium quality features? Obviously NOT.

While picking the best sump pump for crawl space, it is significantly essential to know the required considerations.

Below are the most important considerations that you will need to keep in mind.

Sump Pump Types

A sump pump is 2 in type. The pedestal and submersible sump pump. However, both deliver the same result, removing water from the basement or crawl space before it can flood the crawl space.

A submersible sump pump needs to be installed below the foundation level. Typically, you have to break the concrete, and digging a hole is mandatory to install the pump.

On the other hand, to install a pedestal sump pump, breaking the concrete is entirely unnecessary. They are placed on a stand. These sump pumps create much noise compared to a submersible sump pump. Besides, they provide 5 – 15 years of service without showing any trouble.


Sump Pump Durability

Durability is always one of the essential factors of any kind of device. Generally, sump pumps are made of different materials, and the commonly used materials are stainless steel, plastic cast iron, and thermoplastic.

The characteristics of thermoplastic are unique. When you make them heated, it will be easily moldable, and when it gets cool, it will become hard like a rock. When used for sump pumps, this material is specially used to manufacture casings, pedestals, and other parts of a sump pump. In contrast, metal or aluminum are used for making the motor.

While plastic is a commonly used material because of its cost-effective feature, it is inexpensive compared to thermoplastic. But in terms of durability, plastic-made sump pumps are less durable.

When the sump pump was invented, cast iron was the material that was used more. Since cast iron is a bulky material, it started losing popularity among many manufacturers, and nowadays, manufacturers don’t use cast iron to manufacture submersible sump pumps.

Cast iron-made sump pumps are much durable, but durability will be ensured if you take proper care of them. Unfortunately, these types of sump pumps are rust and corrode-prone.

On the other side of the coin, stainless steel is much durable and lighter than different types of sump pump material. Taking good care is also not required since steel is rust-resistance. Overall, stainless steel is the best material to manufacture both submersible and pedestal type sump pumps.


The sump pump has 2 types of ratings that show how much efficient a sump pump is. The first rating is GPH (Gallon Per Hour). This rating tells how much water a sump pump can discharge from a basement or crawl space in an hour, and the water is measured on the gallon unit.

However, you may think, higher GPH is the indicator of a better sump pump. But it is not the actual case. Higher GPH sump pumps consist of larger motors, they consume more electricity, and if enough water is unavailable to continue the cycle, they may get burnt out.

“Head Rating” is the other one that plays a vital role. The measurement of the discharge height and length is known as the head rating. Both GPH and Head Rating will give you the water flow rate of a sump pump. The best sump pump for crawl space will come with the best GPH rate, enough to keep your basement or crawl space dry, and a large Head Rating to remove water from your home.

The range of standard GPH ratings is 2,400 – 3,000, and the Head rating is 10’.

Power Source

Most of the sump pump is electricity-powered. It would be best to connect your sump pump to a GFCI outlet to avoid fire or electric shocks.

Few sump pumps are available with a built-in battery backup mechanism. During a power outage, the battery will give power back up to the sump pump. You will remain worry-free if power is unavailable for an extended period because your sump pump will continuously work with the help of battery backup.

Switching System

The truth is that people don’t consider looking at the switching system while purchasing a sump pump. 2 types of switching systems are available. Automatic and manual. It is one of the vital factors that need to be taken into consideration.

The automatic system contains a floater that engages the motor. Once the float gets pushed upwards by water, the motor will click on it. The working procedure of this float is similar to a toilet tank fill valve (only reverse) that permits water to fill the tank so that the floater can be raised sufficiently.

For homes situated in a coastal area or in those areas where heavy rain is frequent, an automatic system is the best option. With the help of an automated system, a sump pump will start working automatically, and a homeowner will not be required to check frequently if the pump is working or not. Additionally, this type of sump pump is best for crawl spaces too.

On the other side of the coin, continuous hum can become too much for some people. At this point, a manual switch system will be the right choice. This type of sump pump contains a toggle switch rather than a floater, and it is powered through a light switch or a 2-way push button.

If you require to run the manual sump pump, simply flip the switch manually. It helps to save energy, although not too much as well as you will never experience false-alarm in this type of sump pump.

Installation Cost

How will you determine the sump pump installation cost? Well, the process is a bit tricky.

First of all, figure out the type of floor you will need to dig. If the floor is made of concrete, you will need to break it, and shoveling away is enough for gravel-type floors.

If you plan to replace your sump pump due to any reason, it means a few installations work as the drainage system has already been done, so the labor cost too. Besides, you can save more money if you make the installation process a DIY project.

It would be best if you install a sump pump by a professional. A higher cost means the installation process is done correctly. If the installation process gets wrong somehow, you will need to bear more bucks in the future. A professional will ensure that there will be no issue after the installation process, and the sump pump will work at its best.


Sump pump warranty varies on the type. The lifespan of a submersible pump is 5 – 15 years. The pedestal pump will deliver 20 – 30 years of service. The materials for construction, installation of the pump, and maintenance will be performed during the warranty period provided by the manufacturer.

2 – 5 years of warranty will be covered by most of the manufacturers. Also, you will get 10 years of warranty for other parts. However, different manufacturers will provide a separate warranty for your sump pump.
