Submersible Pump Basic-Sizing / AY McDonald

Each water well system is unique. There are varying depths to the water table and each home has its own unique plumbing system and network of pipes.

Because of these differences, not all well pumps will work properly for all systems. Each system should be sized properly and matched with the correct pump.

When hiring professional well drillers for pump installation, your contractor will typically determine the correct pump size for the well and household by applying a series of mathematical formulas based on water needs and the nature of the environment. But whether you're hiring contractors or installing a pump yourself, it is important as a well owner to understand the logic behind pump sizing.

The well contractors may ask you to provide some of these numbers so it'll be helpful to understand how to get them.

Calculating the numbers

There are two important numbers needed in order to determine the correct pump size for a well system, known as GPM and TDH. GPM refers to the required amount of water the household needs, measured in Gallons per Minute. TDH (total dynamic head) refers to the total amount of resistance the pump will encounter when attempting to push the water upward.

Determine required flow rate in GPM

It is important to measure the average amount of water the household will be using in order to determine the correct pump size. Water needs will vary depending on family size and other factors. There are two common methods for determining GPM for a residential pump system, both giving similar results.

Capacity based on fixture count - Flow rate can be determined in gallons per minute based on the number of fixtures in the home. A fixture can be considered any appliance that provides an outlet for water including sinks, toilets, showers, faucets, outside irrigation, the pool, and other special fixtures such as a hot tub.

For this method, each fixture equates to 1 gallon per minute. For example, a home with two bathrooms having 3 fixtures each, a kitchen sink, dishwasher, washing machine, laundry tub, and two outside hose outlets equates to a total of 12 fixtures. With 12 fixtures in total, a capacity of 12 GPM will be required for the entire household.

Capacity based on peak demand - This model calculates the capacity based on a seven-minute peak demand. The peak times for water use in households are usually in the morning when the family rises to prepare for the day, and in the evening, when all family members are at home. Seven minutes is the average timeframe of high water use for a shower or automatic washer.

The average peak demand for a 2-bathroom home is 98 gallons which translates to a requirement of 14 gallons per minute. You can source your required gallons per minute online based on various scenarios - 2 baths, 3 baths, etc.

Note that these are rough estimates and won't provide an exact account for water demand. For a more accurate account, consult more in-depth flow rate guides.

Total Dynamic Head

The total dynamic head (TDH) is the sum of a series of measurements that represents the amount of "work" that the pump will have to endure in order to provide the required amount of water at the other end. TDH is typically calculated by the drilling company or the contractors responsible for pump installation. As a well owner, it is important to understand the basics of TDH.

Because TDH refers to the total amount of resistance a pump will encounter, it involves a series of factors including friction, well-depth, and the distance the water must travel. In order to understand TDH, there are a few basic concepts which must be defined.

Drawdown level - The level at which the water remains when the pump is not on is referred to as the static level. When the pump is turned on, the water level typically drops.

This is referred to as the drawdown level or pumping level. In order to calculate TDH, one would need the distance (in feet) from the top of the well to the drawdown level.

Vertical lift - The elevation difference, or vertical lift, is the distance (in feet) from the top of the well to the highest point of the pressure tank. The pressure tank is the highest point above ground where the pump will cause water to rise.

Friction loss - Friction loss refers to the amount of resistance the water will encounter when flowing through the various sizes of piping. By referencing a friction loss chart, total friction loss can be determined by factoring in pipe material, pipe width, and pipe length.

Service pressure - Service pressure, also known as operating pressure, refers to the amount of water pressure released at the outlet. Most homes operate at a pressure range between 30 to 80 psi.

After the drawdown level, vertical lift, friction loss, and service pressure have been determined, TDH can be calculated by combining them:

TDH = drawdown level + vertical lift + friction loss + service pressure

Determine pump according to manufacturer's curve chart

After the flow rate in GPM and the TDH have been calculated, an appropriate pump may be selected by referencing the manufacturer's curve chart. Each pump manufacturer will have its own chart system for referencing their specific pump models. By noting the TDH and GPM, the exact pump model and HP required can be determined.

Consult the help of your contractors

Unless you're a licensed driller yourself, you'll likely be consulting the help of professional pump installers when drilling or installing a pump for the first time. They'll be able to provide you with help in determining your GPM and TDH. Nevertheless, it is important as a well owner to understand how to size a submersible well pump.

For a more in-depth guide on how to size a pump, check out A.Y. McDonald's excellent pump sizing guide.

Centrifugal Force

Rather than sucking water out of the ground like above-ground well water pumps, submersible pumps use centrifugal force to push water to the surface.

By harnessing the laws of physics rather than working against it, submersible pumps typically have fewer mechanical problems than jet pumps and can last up to 25 years before needing replacement.

They are cylindrically shaped, about 3 to 5 inches in diameter, and 2 to 4 feet long. The airtight-sealed, close-coupled motor prevents the water from getting in and causing a short circuit. A waterproof electrical cable runs power from the power source all the way down to the pump.

Impellers in the Well Pump

When the pressure switch is turned on, an electric current is sent down the electrical cable connected to the motor. This causes the impellers within the body of the pump to start rotating. Once the impellers start rotating, they will suck water into the pump body.

The impellers will then push the water upwards through the well casing and into the water tank. When the pressure switch is turned off, the electric current stops flowing to the pump, thus shutting it back off.

2-Wire vs 3-Wire

The main difference between 2-wire and 3-wire pumps is the fact that 3-wire pumps are accessed by a control box while 2-wire pumps are not. The advantage of having a control box is that some of the major starting components are housed in the above-ground control box and not in the pump itself.

These components can be accessed and replaced individually without the need of having to pull up the entire pump should anything break down.

In a 2-wire pump, the starting components are housed inside the pump itself. The main advantage to 2-wire pumps is that installation is much easier and because the components are housed together, breakdown is less likely than a pump with a control box.

Horsepower

Residential submersible pumps typically come in 1/2 HP, 1 HP, or 3/4 HP settings.  In general, the greater the depth of the well, the harder the pump has to work to lift water to the surface.

The higher the HP, the greater the flow rate at greater depths. The required HP for your system will be determined by following the manufacturer's curve chart after GPM and TDH have been established.

GPM/Flow Rate

Each pump has a potential flow rate that may be achieved depending on the depth of the well. The deeper the well, the harder the pump has to work in order to lift it up.

The pump manufacturer may list settings such as 12 GPM @ 80 ft. and 14 GPM @ 40 ft. Notice that the flow rate differs depending on the depth.

Because flow rate is dependent on the depth of the well along with various other factors, it is important to have your well system properly sized before purchasing a pump.

Voltage

The standard voltage for a submersible pump is 230V. Anything less could be inefficient and could be potentially hazardous.

Max PSI

Some manufacturers will state the pump's maximum PSI. This means that the pump will not operate at pressure higher than what's listed.

As the name implies, submersible pumps stay submerged underwater and work to push water up the well. They remain underground and out of sight, and are only resurfaced when in need of repair or replacement.

Over the last several decades, many well owners have switched from jet pumps to submersible pumps. Listed below are some of the reasons why.

Durability

Submersible pumps, because of their inaccessibility after installation, are designed to function without the need for frequent maintenance. The internal components are kept safe inside the metal casing allowing for long-term, undisturbed performance.

Submerged 90 to 300 feet underground, the only outside element the pump will come into contact with is water. While occasional inspection is encouraged, a good submersible pump that is properly installed and sized could last up to 25 years before needing replacement.

No Need for Priming

Prior to using an above-ground jet pump, it must be properly primed with running water in order to function properly. Priming is a time-consuming process and can often take several attempts before successfully activating the jet pump. A submersible pump, because it is already submerged in water has no need for the priming process.

Above-ground pumps are also prone to cavitation, a problematic situation where excess air and gas enter the mechanical components of the pump. Submersible pumps do not have this problem.

Efficient Design

The entire mechanism is housed in a tightly constructed cylinder that pushes water upward rather than sucking it from above. The rapidly spinning impellers use centrifugal force to drive water up the shaft – a much more effective way of challenging the downward force of gravity.

Because of the physics involved in the design, submersible pumps have a lighter mechanical workload than that of the lifting motion of jet pumps and are therefore less prone to breakdown.

Greater Depth Range

While above-ground jet pumps are used for more shallow well depths of less than 25 feet, submersible pumps are used for deeper wells and cover ranges of 90 to 300 feet and greater.

Out of Sight / Out of Earshot

Jet pumps can be quite loud and unsightly, especially large ones with greater GPM. Submersible pumps are underground and therefore can't be seen or heard.

As submersible well pumps are enclosed, they generally have a long productive life. Failures are typically due to corrosion of the seal. The pump's seal can corrode over time which allows water to seep into the motor, leading to motor failure. Once this happens, the most cost-effective choice is to replace the pump.

There are several signs of pump failure. These are some signs along with steps you can take to troubleshoot.

Absence of Water at the Faucet

When there is an absence of water, first check the circuit breaker. If it is switched off, switch it back on and check the faucet. If there is still no water, the problem may lie with the pump or the pressure switch on your storage tank. In this case, it will be best to contact your well water professional.

Aerated at the Faucet

If your water is aerated at the faucet, it can result in sputtering which may signal a pump failure. It may also indicate that your pump is above a lowered water table, or there is a bad check valve or a cracked pipe. In this case, the best solution is to contact your well water professional.

Sudden Change in Water Quality

Sudden changes in water quality, like cloudiness or muddiness, indicate that sediment is entering the pump which can wear down the pump's internal elements. This issue can be resolved by lowering the pump deeper.

A Spike in Your Electric Bill

A spike in your electric bill may indicate that your pump is working overtime, which may in turn indicate a pump failure.

Note that abrupt pump failures are not common. Certain weather conditions like drought can lower the water table in your well, which can affect how the pump operates. You can check this by not using your water for several hours to allow your well to replenish. If the water flow returns to normal, the wells replenishment rate is low due to natural conditions. The issue may be resolved by lowering the pump deeper into the well or hydrofracturing to increase replenishment rates.

Make sure to schedule annual preventive maintenance inspections to reduce the possibility of a failure. Discovering the problem early will result in a lower-cost repair as opposed to a complete replacement.

The pump is the heart of any well water system. As is the case with any circulatory system, it is imperative that the heart be strong, efficient, and long-lasting. Selecting a proper submersible pump is one of the most important decisions a well owner can make. Be sure to become familiar with the mechanics behind well pumping and the nature of the environment around you. Communicate closely with the well drillers and those responsible for installation of the pump. With good preparation and proper maintenance, your submersible pump should last a long time.
