🧾 Buyer’s Guide: How To Buy The Best Submersible Well Pump
In this section, we’ve covered everything you need to know to buy the best submersible pump for your requirements.
Understanding How Submersible Pumps Work
There’s a lot of confusing data and lingo in the submersible well pump world, so it’s good to learn the basics of how submersible pumps work before you start your search.
Submersible pumps are well pumps that are designed to be installed underground, at the bottom of the well. They’re about 2-4 feet long, with a cylindrical shape and a diameter of 3-5 inches.
These pumps contain a motor and an electric cable, which travels from the power source to the pump’s underground location.
The key distinguishing performance feature of a submersible well pump is that it uses centrifugal force to push water to the surface of the ground.
This is different from above-ground jet pumps, which suck water up from the well.
When the pump is switched on, its impellers rotate, sucking water inside the pump. This water is then pushed up the well and into your home’s well pressure tank.
When the pressure tank is full and the pump switches off, electricity to the pump is shut off until the pressure tank needs to be refilled once more.
How To Buy The Right Submersible Pump Size
Submersible pumps come in a plethora of sizes, and buying the right size pump is essential to ensure you get the correct flow of water for your household size and water needs.
Why do different submersible pump sizes exist? Because the water table has varying depths and homes have their own unique plumbing systems and water delivery needs. A single pump size wouldn’t work properly for all well setups, which is why you should put a lot of research and effort into working out the correct well pump size for your well.
If you’re hiring a professional contractor to drill your well, they should provide this information for you. But if you’re installing the pump yourself or you just want to understand how to size a pump, here’s what you need to know:
GPM and TDH
The two numbers that are the most helpful in helping you to correctly size a well pump are
- GPM – Stands for gallons per minute, refers to the volume of water that a household plumbing system needs to supply to meet water demands
- TDH – Stands for total dynamic head, refers to the total amount of system pressure where water can flow upward through a system before resistance from gravity takes over
How To Determine GPM
Let’s start by looking at how to determine your required well water pump flow rate.
You can use one of the two following methods to get a rough estimate of your water demand and the most suitable GPM rating for you:
Method 1: Count Your Fixtures
A quick and easy way to determine flow rate is to count the number of fixtures, including sinks, washing machines, showers, outside hose outlets, toilets, pools, and dishwashers, in your home.
Assign 1 gallon per minute to every picture. So, if you have a total of 10 fixtures in your home, you’ll need a 10 GPM flow rate to meet your household’s water needs.
Method 2: Base Flow Rate On Peak Demand
Another method is to base your required flow rate on your home’s peak demand over 7 minutes (the average time period of maximum water usage in a washing machine, shower, etc.).
A 2-bathroom home has an average 98-gallon peak demand, which requires an incoming flow rate of 14 gallons per minute. You can search online to find your ideal GPM for the number and bathrooms and bedrooms your home has.
Keep in mind that the actual flow rate provided by your chosen well pump depends on the depth at which the pump is installed. The deeper the well, the lower the flow rate once the water reaches the pressure tank.
So, a well water pump with a 14 GPM flow rate at 40 feet deep will likely have a reduced flow rate of 12 GPM at 80 feet deep.
How To Determine Total Dynamic Head
Total dynamic head (TDH) is more difficult to measure but is equally important to get right if you want to accurately size a submersible pump for your well.
TDH measures the total resistance encountered by a pump, which means that static water depth, frictional losses in the pipe, well depth, and water travel distance must all be considered.
The sum for calculating TDH is:
Drawdown + Frictional Losses in Pipe Vertical Lift + Operating Pressure = TDH
Some of the key terms that will help you to understand how to calculate TDH are:
- Drawdown level/pumping level – The level that water sits at when the pump isn’t on. This level typically drops when the pump is switched on. You will need to work out the distance (in feet) from the top of the well to the drawdown level.
- Friction loss in pipe – The resistance encountered by the water when flowing through the pipes in your plumbing. Friction loss depends on your pipe length, width, and materials.
- Vertical lift – The distance (in feet) from the top of the well to the highest point that water will rise to (the top of the pressure tank).
- Operating/service pressure – Operating pressure, or service pressure, is the water pressure in your home and typically ranges between 30-80 PSI.
Reading The Manufacturer’s Curve Chart
You can now bring all this information together to determine the best-sized pump for your home by referencing the manufacturer’s curve chart.
All good manufacturers should share a curve chart for each of their pump configurations that tells you the pump’s performance capabilities based on testing.
You can use a curve chart to determine how many gallons per minute a pump is capable of pumping, how many feet, and the ideal operating performance for efficiency. Compare this information to your GPM and TDH findings to choose a pump that’s suitably sized for your home.
Confused? Speak to a licensed professional. A professional well pump installer can help you determine the right submersible pump for your needs.
2-Wire vs 3-Wire Pumps
There are two wire options that you’ll come across when shopping for submersible pumps: 2-wire pumps and 3-wire pumps.
The key difference between tow two is that a 2-wire pump isn’t accessed by a control box, while a 3-wire pump is. Having a separate control box is advantageous because it means that accessing some of the pump’s major components can be done above-ground, so maintenance and repairs are easier.
A 2-wire pump houses these components underground, in the pump, which means that installation is quicker and easier, and breakdowns aren’t as common due to all the components being stored in the same location.
Consider Your Well Depth & Horsepower Requirements
You already know how to choose a pump with the right flow rate, but what about horsepower?
Submersible well pumps for residential use are typically in three horsepower options:
- 1/2 HP
- 3/4 HP
- 1 HP
You can also find pumps with 2 HP and 3 HP settings if you have a very large or deep well, or you need a pump for commercial use.
In a deep well, the pump must work harder to lift water to the surface compared to a shallower well. So, an increased horsepower is required.
As horsepower increases, so does the pump’s flow rate potential at greater depths. You can use the manufacturer’s curve chart to work out the best HP for your submersible pump based on what you already know about your GPM and TDH.
Understanding Pump Voltage
There are three common voltages for submersible well pumps:
- 230 volts
- 110 volts
- 115 volts
230V is the standard voltage for a submersible pump and is recommended in most cases. However, pumps that are intended for shallower wells don’t require the same power and may do fine with 110V or 115V.
If you’re not sure, we advise buying a 230V pump to ensure you have sufficient power for supplying water from your well at all times.
Consider Your Budget
Your budget is one of the most important factors to consider when you’re deciding on a suitable submersible well pump.
Smaller submersible pumps cost as little as $150-$350, while larger pumps may cost upwards of $1,000.
Remember, you’re probably not only paying for the pump – you will also need to budget for professional installation.
The average cost of buying and installing a submersible well pump is $1,000-$2,750.
It’s a good idea to get a quote from a professional well pump installer before you buy the pump, so you can be certain up-front that the installation is within budget.
Comparing Submersible Pumps To Jet Pumps
Submersible pumps are only one of the well pump options to choose from. If you’re still trying to decide between submersible and jet pumps for your well, consider the following:
- Durability – Submersible pumps are designed to be durable and require minimal maintenance because of their inaccessibility once they’ve been installed. Jet pumps can last up to 20 years, while submersible pumps last 25+ years.
- Maintenance – Jet pumps tend to be easier to maintain because they’re installed above ground. However, they often require more maintenance because they’re prone to cavitation (caused by excess air in the components).
- Priming – Jet pumps need to be primed before use, while submersible pumps don’t need priming because they’re already submerged under water.
- Design – Submersible pumps have a more efficient design than jet pumps because they push water upwards rather than sucking it from ground level. This reduces their mechanical workload and reduces their likelihood to develop technical issues.
- Well suitability – Jet pumps are intended for shallower wells less than 25 feet below ground, while submersible well pumps can be used in wells as deep as 300 feet, sometimes even deeper.
- Sound level – Jet pumps are noisier because they’re installed at ground level, while submersible pumps are deep below the ground, so noise isn’t an object.
❔ Best Submersible Well Pumps: FAQ
What size submersible pump do I need for my well?
The right size submersible pump for your well depends on factors including your daily water demands, your well depth, the pump horsepower, and the size, material, and length of the pipes carrying water to your home. You can determine the most suitable pump size by working out your required flow rate (in GPM) and your total dynamic head (TDH).
Is it better to have a higher HP well pump?
The higher the pump’s HP, the better suited it is to a deeper well. However, you don’t necessarily need to buy the highest horsepower pump you can find. A good HP range for residential use is 1/2 HP to about 2 HP. It’s unlikely that you’ll need a 3 HP pump for your private well.
What is the best brand of submersible pump?
Some of our top recommended brands for submersible well pumps are Hallmark Industries, Flotec, Red Lion, Vevor, Grundfos, and Schraiberpump. Make sure your chosen brand has enough industry experience, positive customer feedback, and professional recommendations to be considered reputable and reliable.
What is better: 2 or 3-wire submersible well pump?
A 3-wire pump is generally considered the better option if the pump motor is 1.5 HP or higher, which will ensure that the motor starts and runs properly. A 2-wire setup is usually fine for less powerful pumps. Speak to your local well contractor if you’re unsure.
