Final Verdict

Hallmark MA0419X Deep Well Submersible Pump

Submersible well pumps vary dramatically in capacity and pressure, with some working in wells over 500 feet deep. Although some families need as little as 10 gallons per minute at peak demand, families with larger homes may need closer to 18 at peak demand.

Pumps and well capacity should be carefully assessed, especially if your home has had water pressure problems in the past.

Overall, the Hallmark Industries MA0419X-12A Deep Well Submersible Pump is the best deep well pump. It provides water from depths up to 400 feet, which is more than sufficient for most rural wells. It provides up to 35 gallons per minute, and still provides generous PSI at lower depths.

Hallmark's pumps are known for being long-lasting without being as expensive as some competitors. They are extremely sturdy and have solid wire casing to protect sensitive electronics from damage.

A new submersible deep well pump can improve a home's water supply significantly. If your home's well water pressure has been dropping, that's a sign that the pump has been worn down and needs replacing.Families who still rely on municipal water may also find that a deep well submersible pump can provide fresher, faster water at a fraction of the price.


How to Pick the Perfect One for Your Needs 

Well pumps are designed to deliver a certain number of gallons per hour. Most well pumps for residential use provide at least 600 gallons per hour, with some capable of providing over 1,800. Single-family homes need far less than 1,800 gallons per hour but may still need large amounts of water in short bursts.

A well pump that doesn't provide enough water causes drops in water pressure during showers, washing machine cycles, and other peak usage times. The size of your home and number of appliances make the biggest impact on water usage.

A very small house rarely uses more than 10 gallons of water per hour, while a 4-bathroom house may use 18 gallons of water per hour at peak times.

Some deep well submersible pumps work in wells over 600 feet deep. Though they can technically be used in wells less than 100 feet deep, high-capacity models may provide much higher PSI than necessary.

Other considerations include ease of installation and warranty. Though most installation jobs require professional assistance anyway, pumps that are easy to install have a reduced risk of delays or eventual maintenance problems.

Look closely at the best submersible well pump reviews to get an accurate picture of which pumps provide the best overall experience for installation and repairs.

For easier maintenance, get a 3-wire submersible pump with a separate control box. A 3-wire pump can sometimes be repaired without bringing it up to the surface. Though 2-wire pumps are easier to install, they must be brought up to the surface every time they need a repair.

The estimated lifespan of a pump also matters. A good pump should last 8-10 years, with some lasting up to 25 with proper care and maintenance. Longer is always better, but keep in mind that estimated lifespans can vary based on several factors, including local water sediment.

You can increase the life of your pump by minimizing the number of times it stops and starts cycles. One way to do this is by attaching a larger pressurized tank for water storage. This tank helps by evening out the sudden starts and stops in water demand, taking stress off of the pump.

Submersible well pumps can be ordered online once you've concluded which pump works best for your home. A local company may need to install it in a new well, but replacement pumps can be DIY installation jobs with some plumbing tools and careful planning.

How to Accurately Size It 

Buying the appropriately sized well pump requires a careful look at every room in the house. One method of sizing a well pump requires counting the number of showers, sinks, toilets, dishwashers, and laundry machines across all rooms. If you have outside faucets for garden hoses, include them in the number of sinks in your calculation.

Once you've double-checked the number of water fixtures, use that number as the number of gallons per minute you need. For example, if you have 14 total fixtures, you should get a pump that provides at least 14 gallons per minute.

Alternately, you can size a submersible pump based on peak demand. If everyone in your home showers in the morning, for example, a peak demand calculation may provide a more accurate look at how many gallons per minute or hour you need. This also may provide a more accurate picture for pools, hot tubs, and sprinkler systems.

You also need to look at how much water your showers, laundry machines, dishwashers, and sinks use. Typically, showers and washing machines each use 5 gallons per minute, and toilets and sinks use 4 each. Dishwashers only use 2 gallons per minute.

Pools, hot tubs, and sprinkler systems can be tricky to include. These amounts can vary widely, so check the documentation provided with each system to determine its water usage.

Sprinkler systems also require up to 40 PSI of pressure, which can cause a drop in pressure to other fixtures if the pump is not supplying enough.

Keep in mind that peak demand can fluctuate if you host guests. If you only have two people living at home but sometimes have overnight guests, calculate peak demand based on the maximum number of guests possible at one time.

When calculating based on potential peak usage, you may get a number that's much higher than the number of fixtures in the home. If you're uncertain of your calculations, there are also industry standards to use as a guideline. For example, a 2- or 2 ½-bathroom home needs a pump that provides at least 14 gallons per minute.

Some pumps provide their capacity in gallons per hour, but most homes won't sustain their peak demand for a full hour at a time. Most showers are much less than an hour, and laundry machines' peak usage is just seven minutes.

A submersible well pump is also typically used with a pressure tank to help manage water flow, so a pressure tank should be selected in accordance with your home's peak demand.

When water is drawn out of a pressure tank instead of directly from the pump, the pump has extra time to catch up to meet demand.

Pressure tanks are also important for wells that can't consistently provide enough water during peak demand. Even the best pump in the world can't pull water from a dry well. Pressure tanks allow water to be brought to the surface as soon as it's available in the well, then stored for use once it's needed.


Benefits

Clean water anywhere

Submersible well pumps can be installed anywhere the water table is high enough to provide a steady supply. Even extremely rural areas can get a long-lasting well dug. Wells provide a much more reliable supply of water than rainwater collection without building huge storage containers that use a lot of space.

Reduced utility costs

Water utility costs are high in some areas, so submersible well pumps can reduce long-term costs. Though submersible wells have up-front costs and occasional maintenance costs, they can be significantly less than comparable utility costs. Even filter replacement costs are low and infrequent.

More reliable than shallow well pumps

Shallow well pumps and convertible jet pumps can be prone to maintenance problems. They sometimes require re-priming after a power outage, and they may require other troubleshooting if bubbles appear due to low water pressure. Submersible wells avoid these common problems because they are fully submerged in the water source.

Can improve water pressure as needed

Municipal water lines require families to wait around for utility workers to make repairs if there is a water pressure problem or other issues. Sometimes, the utility company may even try to claim that a water pressure problem isn't their fault. With submersible well pumps, homeowners can take control of their water supply and make any adjustments needed over time.

Cleaner water

With appropriate maintenance and filtration, well water can be cleaner than city water. Improvements in filtration technology make it possible to have perfectly clean well water free of rust and other contaminants. You can easily monitor and address issues yourself instead of waiting for utility officials to act.

Years of use

Submersible well pumps can be used year-round without winterization. They typically need replacing every 8-10 years but last for up to 25 years in optimal conditions. They give peace of mind and a significant return on your investment.


Submersible vs Shallow Well Pumps 

Shallow well pumps, including convertible jet pumps, are designed for wells up to 25 feet deep. They sit outside the water in a separate area called a well housing. The pumps pull the water out and send it through pipes for filtration and storage.

Shallow well pumps must be manually primed before use, and sometimes require re-priming after loss of power. They also can develop minor problems due to cavitation, or bubbles forming in the water supply.

During the winter, shallow well pumps must be winterized unless they are kept in housing below the frost line.

Convertible jet pumps can be paired with an ejector to pull water out from up to 90 feet deep. These pumps are helpful for homeowners with water tables that fluctuate seasonally but still may require more maintenance than submersible pumps.

Submersible well pumps can work in any water depth, although some may deliver excessive PSI in wells less than 100 feet deep. They also avoid many of the maintenance issues of shallow well and convertible jet pumps. They can be difficult to install, but external control boxes make it easy to use and adjust them after installation.

All three types have comparable average lifespans of around 10 years. The depth of your well ultimately decides the best option for you.

2-Wire vs. 3-Wire

Two-wire submersible well pumps have two electrical wires plus a grounding wire. These pumps are easy to install and use, since only the power supply and water pipe need to be attached.

Three-wire pumps have an additional wire to connect to the pump's external control box. This box is typically placed near the pressure tank and provides an easy method for turning off the power or adjusting pressure settings.

The right pump for you will partly depend on if you want to install the pump yourself. Two-wire pumps are easier to DIY install, since there is no control box to worry about. However, they are more difficult to troubleshoot yourself if they ever need maintenance or repairs.

Three-wire submersible well pumps may require professional assistance to install, depending on your familiarity with well systems. Even if your previous pump was 3-wire, the control box might not be compatible and may need to be replaced. Though 3-wire systems can make maintenance and adjustments easier, there are times when the pump must be pulled out for repairs.

In the end, either wire system is a good option. Some of the best and most reliable pump systems are 2-wire systems, and some are 3-wire. Other features like maximum depth and capacity are much more important.


How Does It Work? 

  • When a faucet is turned on in a house, water moves through the pipes. If the water is only used for a few seconds, the pump may not turn on at all, and the process ends.
  • Depending on the exact settings of the pump and its control box, the pump turns on in response to a drop in water pressure in the pipes. Even if a pressurized tank is between the house and the pump, the pump eventually switches on to provide more water.
  • The pump's motor, which is protected inside a special hermetically sealed chamber, begins to turn. This turns an impeller, which draws water into the body of the pump.
  • As the water enters the pump, it may pass through a pre-filter to keep out sand and other sediment that may clog the pump.
  • The water is pushed up out the pipes attached to the pump toward the house. Depending on how much water is being used, the pump may stay on for a few seconds or for several minutes.
  • The water is filtered and typically stored in a pressure tank until it is needed. Once a faucet or other water fixture is turned on, the process begins again.

Why Do You Need It? 

Submersible well pumps are ideal for rural households who are far from municipal water sources. They are low-maintenance and can be used for cabins, farms, summer homes, and anywhere else in the countryside.

Submersible pumps are also an excellent option for families who are currently using municipal water but have trouble with water pressure or quality. Utility companies sometimes struggle to maintain water pressure at the far edges of their network, and old pipes can cause contamination problems.

A well system allows you to keep control of your water supply and adjust pressure and filtration as needed.

The up-front investment of a water pump can translate into major long-term savings. If your land has a high enough water table, installing a well can both increase the value of your property and allow you to stop paying municipal water fees. Submersible pumps can last up to 15 years in low-sediment water.

Shallow wells that currently use a shallow well or convertible jet pump can also benefit from a submersible well pump. Submersible well pumps require less maintenance and don't need winterization or re-priming.

Submersible well pumps may also become necessary if your well has started to dry up. Digging a deeper well and installing a submersible pump can help ensure years of clean and reliable water for your family.


How to Install/Replace 

Once an initial well system is installed, replacements can be done by DIY enthusiasts. Disconnect the power at the circuit breaker and unscrew the well cap, then get a pitless connector wrench to unscrew the pitless connector that's on the side of the well casing.

With help from at least one other person, pull out the old pump, taking care to avoid damaging wires. Remove the torque arrestor, then disconnect the wiring, water pipes, and safety line.

Depending on the condition of your existing system, you may need to buy and install new wiring. Any wire connections that must be placed inside the well casing should be soldered, then protected with waterproof heat-shrink tubing.

Reconnect the water pipe, safety line, and torque arrestor, then test the pump in a 10-15-gallon container of water if possible. If everything works, disconnect the power again and lower the pump back into place. Line the pitless connector up and push it back into place, gently hitting the wrench with a hammer as needed to secure it in place.

Adjust the pressure tank and well pump switch as necessary to deal with any differences in your new pump. You may need to disinfect your well if it hasn't been cleaned recently, but if not, your new pump is fully ready to use.


FAQs 

How long do submersible well pumps last?

Submersible well pumps typically last 8-10 years but may last up to 25 in optimal conditions. Pumps may burn out sooner if the water has many fine particles or if the pump is not properly maintained.

Can you use a submersible pump in a shallow well?

Submersible pumps can be used in shallow wells, but some models may provide excessive PSI at lower depths. If you want to use a submersible pump in a shallow well, look for one that has low horsepower and is rated for use up to 100-150 feet.

Can submersible pumps run continuously?

Though submersible pumps are technically capable of running continuously, they should not need to. Well pumps are designed to turn on when water pressure in the pipes or pressure tank drops. When all water fixtures are shut off, the well pump should refill the pressure tank and shut off in a few minutes.

How deep can a submersible pump go?

Submersible pumps' depth limits vary based on model, but some work at depths over 600 feet. Keep in mind that the gallons per minute and PSI of pumps is reduced at lower depths, so it can be a challenge to get above 10 gallons per minute even with high horsepower.
