For most homes, there is no single water-pump company that is best in every situation. Grundfos is a strong all-around choice for household pressure boosting. Franklin Electric is especially strong for wells and complete groundwater systems. Davey and DAB are also worth considering for home pressure, tank, and rainwater systems.
The better question is: Which company makes the right type of pump for your water source and the pressure and flow your home needs? A very good pump from the wrong category can still perform poorly or fail early.
Best Water Pump Companies by Home Use
| Home use | Company worth considering | Why it fits |
|---|---|---|
| Low household water pressure | Grundfos | Strong focus on residential pressure boosters |
| Well water | Franklin Electric | Broad range of well pumps, motors, controls, and protection |
| Rainwater tank or cistern | Davey, DAB, Grundfos, Franklin Electric | Several pump types made for stored-water applications |
| Constant-pressure home system | Grundfos, Davey, DAB, Franklin Electric | Variable-speed and automatic pressure systems are available |
| Simple surface or transfer pumping | Franklin Electric, Davey, DAB | Broad centrifugal and self-priming pump ranges |
These are not rankings based only on brand reputation. Each company serves different parts of a home water system.
Grundfos: A Strong Choice for Home Pressure Boosting
Grundfos is one of the first companies to consider when the main problem is weak or changing household water pressure.
Its residential range includes integrated booster pumps designed to increase pressure from sources such as municipal supplies, tanks, wells, and rooftop storage. Grundfos says its SCALA pumps are designed specifically for household pressure boosting.
An integrated booster can be useful because several parts of the pressure system are combined into one unit. Depending on the system, this may include the:
- pump
- motor
- pressure sensor
- controller
- small pressure tank
- check valve
Variable-speed models can change pump speed as water demand changes. This helps maintain steadier pressure when someone opens another faucet or shower.
Grundfos also offers dry-run and other pump-protection features on some residential systems. Exact features depend on the model.
Grundfos makes the most sense when
Consider Grundfos if you have adequate water available but need better pressure throughout the house.
It can also be a good fit when you want a compact automatic system instead of assembling a conventional pump, pressure tank, switch, and controls separately.
Do not select the pump from brand name alone. Check the required flow, pressure, suction conditions, electrical supply, and installation limits first.
Franklin Electric: A Strong Choice for Well Systems
Franklin Electric deserves special attention if your home's water comes from a well.
The company makes submersible well pumps along with motors, controls, variable-frequency drives, pump protection devices, surface pumps, and pressure systems.
That broad system approach matters with well water.
A deep-well pump cannot be chosen just by horsepower. You need to know things such as:
- well depth
- pumping water level
- distance to the house
- elevation change
- required pressure
- expected household flow
- pipe size
- electrical supply
Franklin Electric also offers jet pumps for shallow-well applications and other surface-pump arrangements.
Franklin Electric makes the most sense when
It is especially worth considering for a new well system, an aging submersible well pump, or a constant-pressure well system.
For a deep well, pump selection and electrical work are normally better handled by a qualified well or pump professional. Pulling and replacing a deep submersible pump can involve heavy equipment, long electrical cables, and significant pipe weight.
Davey: A Good Fit for Home Pressure and Rainwater Systems
Davey makes pumps and controls for household pressure and rainwater applications.
Its home range includes conventional pressure systems as well as variable-speed systems designed to maintain more constant pressure. The company also lists pumps specifically for moving water from rainwater tanks and other stored-water sources.
That can make Davey worth considering when a home uses a cistern or rainwater tank for:
- garden irrigation
- toilet supply where allowed
- laundry where allowed
- other approved non-potable uses
- household supply as part of a properly designed and treated system
Non-potable means water that is not intended for drinking.
A pump does not make collected rainwater safe to drink. Drinking-water use requires suitable collection, treatment, current water testing, maintenance, and compliance with applicable local requirements.
DAB: A Good Choice for Integrated Pressure and Tank Systems
DAB also has a wide range of residential water pumps.
Its products cover household pressure boosting, gardening, irrigation, wells, rainwater reuse, and tank or cistern pumping.
Like Grundfos and Davey, DAB offers electronic pressure systems that can adjust pump operation based on demand. It also makes self-priming surface pumps and submersible pumps for clean-water applications.
DAB can therefore make sense when you want an integrated automatic system, especially for a storage tank or residential booster application.
The Best Company Depends on Your Water Source
Before picking a brand, identify where the pump gets its water.
Municipal water
If your house already receives city water but pressure is low, you may need a booster pump.
A booster does not create more water. It increases the pressure of water that is already available.
Check local plumbing rules before connecting a booster directly to a public water main. Some systems require a break tank or other arrangement, and direct boosting may be restricted. Grundfos also warns that rules for mains boosting differ between locations.
Rainwater tank or cistern
You generally have two main choices:
Surface pump: The pump sits outside the tank and pulls water through a suction pipe.
Submersible pump: The pump operates inside the stored water.
Submersible pumps can be quieter because the tank helps contain the pump noise. Surface pumps can be easier to reach for inspection and service.
Either design can work well when properly sized.
Shallow well
A self-priming jet or similar surface pump may work when the water level is within the pump's permitted suction range.
Do not confuse well depth with suction lift. The important measurement is the vertical distance between the pump and the pumping water level.
Deep well
A submersible well pump is normally used.
The pump pushes water upward rather than trying to pull it a long distance from the surface.
For this application, Franklin Electric and other established well-system manufacturers deserve consideration, but correct sizing is more important than choosing a particular logo.
Do Not Choose a Home Pump by Horsepower Alone
One of the most common pump-selection mistakes is assuming that a larger motor automatically provides a better system.
It does not.
The two numbers that matter most are flow rate and head height.
Flow rate
Flow rate tells you how much water the pump can move over a given time.
It may be listed in gallons per minute, or GPM.
Check comparing brand of pump options to verify startup behavior that reveals air in the suction line.
Your pump needs enough flow for the fixtures or irrigation zones that may operate together.
A pump that supplies one hose easily may not provide enough water for a shower, toilet, washing machine, and garden line operating at the same time.
Head height
Head height describes how much resistance the pump must overcome.
It includes vertical lift along with losses caused by pipe length, pipe size, fittings, valves, filters, and other parts of the system.
As head increases, most pumps deliver less flow.
That is why you should look at the manufacturer's pump curve rather than relying only on the advertised maximum flow.
The pump curve shows how much water a pump can actually deliver at different head levels.
Check Pressure Requirements
Household water systems also need adequate pressure.
Pressure may be shown in PSI, or pounds per square inch.
Higher pressure is not automatically better. Excess pressure can stress plumbing fixtures, filters, valves, appliances, hoses, and irrigation equipment.
The goal is to provide the required pressure while water is actually flowing.
For example, a pump may produce high pressure when almost no water is moving. That does not mean it can maintain that pressure while several fixtures operate.
This is another reason the pump curve matters.
Make Sure the Connections Fit
Before choosing any company's pump, check the inlet and outlet sizes.
Reducing a large pump connection to a very small pipe can increase friction loss and reduce performance.
For a rainwater system, also check:
- tank outlet size
- pump inlet size
- suction pipe diameter
- check valve
- isolation valves
- filters
- pressure tank, if used
- irrigation or household pipe size
Avoid unnecessary restrictions on the suction side of a surface pump. Poor suction piping can cause difficult priming, low flow, noise, and pump damage.
Look for Dry-Run Protection
Dry running happens when a pump operates without enough water.
Water often helps cool and lubricate parts inside the pump. Running without it can damage some pumps quickly.
Dry-run protection is especially useful for:
- rainwater tanks
- cisterns
- wells with changing water levels
- seasonal water supplies
Some modern automatic pumps include built-in protection. Other installations require a separate float switch, level sensor, controller, or pump-protection device.
Never assume the feature is included. Verify the exact pump specifications.
Consider Service and Replacement Parts
A pump may last for years, so service availability matters.
Before choosing a company, find out whether you can reasonably obtain:
- replacement seals
- pressure sensors
- controllers
- pressure switches
- check valves
- motor parts
- authorized repair service
- technical documentation
Franklin Electric provides pump selection and technical-support resources, while Grundfos recommends qualified or authorized service for its integrated SCALA systems.
Local availability can be more important than small differences between two good pump brands.
A pump that your local well contractor or plumber understands and can repair may be a better long-term choice than a less common system with difficult-to-find parts.
For Rainwater Systems, Choose the Pump After the Tank Layout
Do not buy the pump first and design the rainwater system around it.
Start with the water source and intended use.
Determine:
- Where the storage tank will sit.
- Where the water needs to go.
- The vertical elevation difference.
- The pipe length and diameter.
- The required flow.
- The required pressure.
- Whether the pump will be inside or outside the tank.
- Whether automatic operation is needed.
- How the pump will be protected when the tank is empty.
- How filters and treatment equipment affect pressure.
A garden-only rainwater system may need a very different pump from a system supplying several fixtures in a house.
Filters can also create resistance. As a filter collects dirt, its pressure loss may increase. The pump and plumbing need to work as one system.
Which Water Pump Company Should You Choose?
For a typical homeowner, a useful starting point is:
Choose Grundfos when your main goal is compact, automatic household pressure boosting.
Choose Franklin Electric when you have a well or want the pump, motor, controls, and protection designed as part of a groundwater system.
Consider Davey for home pressure systems and rainwater-tank applications.
Consider DAB for integrated pressure boosters, surface pumps, and tank or rainwater applications.
But do not choose any of them until you know the flow and head your system requires.
A correctly sized pump from a reputable manufacturer is usually a much better choice than an oversized pump from the company someone simply calls "the best."
Frequently Asked Questions
What is the best water pump company for a house?
There is no single best company for every house. Grundfos is a strong choice for residential pressure boosting, while Franklin Electric is especially strong for well systems. Davey and DAB also make pumps suited to home pressure and stored-water applications.
What is the best pump for increasing water pressure at home?
A residential booster pump designed for the required flow and pressure is usually the right type. Variable-speed boosters can adjust pump output as household demand changes. Grundfos, DAB, Davey, and Franklin Electric all offer pressure-system options.
What is the best pump for a rainwater tank?
Both surface and submersible pumps can work well. Choose based on required flow, pressure, tank position, vertical lift, pipe size, noise, maintenance access, and dry-run protection rather than brand alone.
Is a bigger water pump better for a home?
No. An oversized pump can create excessive pressure, rapid cycling, noise, higher electrical demand, and unnecessary stress on the plumbing system. Size the pump from its flow and head requirements.
How do I know what size water pump my house needs?
Determine your required flow rate and total head. Include elevation, pipe friction, fittings, filters, and the pressure needed at the fixtures. Then compare those requirements with the manufacturer's pump curve.
Can I use a water pump directly from the city water line?
Sometimes, but local plumbing rules vary. Direct mains boosting may be restricted or require specific equipment. Check the requirements of your water utility or local plumbing authority before installing the pump.
Does a rainwater pump make rainwater safe to drink?
No. A pump only moves and pressurizes water. It does not make roof runoff potable. Drinking-water use requires an appropriate collection and treatment system, current laboratory testing, maintenance, and compliance with applicable local requirements.
