How to Choose the Best Small Sump Pump

small sump pump

You must buy the top small sump pump to suit your individual needs. There are a lot of different things that you need to consider before choosing a particular small sump pump model. Below are the most important things you need to consider when choosing a small sump pump.

HorsePower

The amount of horsepower you need is mostly determined by how big or small of a moisture or flooding problem that you have. Most small sump pumps have a horsepower of less than 1/4 and this is usually enough.

You must identify how much of a flooding problem you have before purchasing a small sump pump. When living in areas that experience heavy rains and have a high water table, you will need a small sump pump with relatively high horsepower.

It is ineffective to buy a small sump pump with less horsepower than what you need to get rid of your problem. When the problem escalates, your sump pump will not be able to comfortably deal with the situation and most of the time it will lead to overheating. In the long run, your sump pump will get permanently damaged.

Pressure

Sump pumps are usually located at the lowest points which mean that they need to provide enough pressure to push the water out. Think of it as your normal showerhead. Imagine for a minute that you are pointing the showerhead in an upward position while trying to direct the water away. When you have more pressure, the water will be pushed higher and further away.

The amount of pressure the small sump pump can generate is pretty important. A good way to know if the small sump pump is generating adequate pressure is by looking at the number of water gallons it can pump per hour. More gallons per hour means the pump generates more pressure and vice-versa.

When purchasing a small sump pump, look at the number of meters your pump can push water. The pressure is mostly measured in meters or feet and is normally specified in the package. You could also do extensive research on the amount of pressure a particular small sump pump provided before making the purchase.

Construction

When looking for the best small sump pump to suit your needs, t is important that you carefully consider the construction. A good quality small sump pump should be made from heavy-duty material that can resist corrosion. Most of the top quality products are constructed from rugged cast iron, stainless steel, and fiberglass-reinforced thermoplastic.

There are a lot of cheap small sump pumps available in the market that simply do not last. This is hugely because they are constructed from cheap materials that wear out easily. This type of small sump pumps is not cost-efficient at all in the long run since you have to replace them very often.

Ensure that you buy a small sump pump made constructed from top-quality material to minimize maintenance and ensure your pump is long-lasting. Keep in mind that the small sump pumps can be used for several other functions and you will need to move them around from time to time.

Power

Most small sump pumps are powered by electricity but some can be battery or water-powered. You must consider a lot of different things when it comes to power.

  • Water or Electric Powered
    Not every person has access to electricity and, therefore some models of the small sump pumps are water-powered. Individuals living in rural areas that experience a lot of power outages could also find it more beneficial to purchase the water-powered pumps. When living in modern places, a standard electric sump pump is usually ideal.

  • Power cord length
    You need to consider whether the power cord can comfortably reach where the power source is. Simply measure the distance from your power source to the required position of the sump pump to know the exact distance before making a purchase.


  • Backup
    You must consider the possibility of needing a backup power source for your small sump pump. During floods, the electronic system might shut down and your sump pump will not function if it doesn’t have a backup power option. You must purchase a small sump pump with a water or battery power backup.

Size

Although small sump pumps are generally considered to be small in size, some sump pits are extremely narrow. Measure the diameter of your sump pit to correctly determine the exact size of the small sump pump that will best suit you.

Sump pits are not standard and it can be quite tedious to increase the diameter of your already constructed sump pit. The best option is to go for a small sump pump that will fit without forcing it or damaging it in the process.
