Buying Guide for the Best Water Pressure Booster Pump

If the water pressure in your home is coming through slowly, maybe even trickling, you may need to install a water pressure booster pump. You should first check a few basics before spending a lot of money on the best water pressure booster.

Check to see if your pipes are in good condition. If they are, great; if not you should see about having them replaced as they might be causing the low water pressure. If the pipes are in good shape, you should next perform a water pressure reading or ask your city water department to do one.

An ideal water pressure reading of 45 to 55 psi is the goal. If your reading is on target contact a licensed plumber, as you may have an obstruction. But if the pressure is low, you may need to purchase a water pressure booster pump.

What is the Best Water Pressure Booster Pump?

A water pressure booster pump is a centrifugal pump used to increase the water pressure. These pumps are designed to increase the performance of your existing pump system, therefore, they cannot transport water on their own. There are a variety of applications for booster pumps and they can be used in conjunction with other pumps when needed.

There are different types of booster pumps available, and their use depends on the head (pressure) and flow needs. The types of booster pumps include:

  • Horizontal split case
  • Multi-stage
  • Single-stage
  • End suction
  • Vertical turbine

Booster pumps have three different key features to look for when choosing which one you need. All three types have varying ranges, the ranges are as follows; flow rate, which can range between five and 10,000 gallons per minute (gpm); total pressure (head) can range between 200 to 7,500 feet; and horsepower, which can range from one and up to 5,000.

How do Pressure Booster Pumps Work?

Booster pumps are centrifugal, meaning they move the water away from a center point. They rely on one or more impellers, drawing the water into the pump which then boosts the pressure as it passes through the impeller.Some booster pumps have a single impeller (single-stage), while others may have more. Pumps with single-stage impellers are for use where the added pressure needed is not a large amount, like in a residence. The multi-impeller (multi-stage) booster pumps are good for use in moving water up a higher elevation or at a longer distance, like in a tall building or for agriculture use.

Where are Pressure Booster Pumps Used?

A water pressure booster pump has many applications, for instance, they can be used for:

  • Pumping water from a well to a house supply
  • Moving water uphill
  • For irrigation systems
  • Pumping water into a large commercial or residential building
  • For reverse osmosis systems and filtration

How To Choose Right Water Pressure Booster Pump

In order to select the pump that will properly fit your needs, you’ll first need to answer two questions. - How far does your water need to travel to reach its intended source?

What pressure is your water currently coming in at?

Knowing this information will get you started on determining which pressure booster pump will work best for your application.

Also note, that horsepower is not the most important feature to look for, so don’t purchase a pressure booster based mainly on horsepower. This is due to the fact that pumps can have the same horsepower but not the same flow rates and pressures.

Some things that you should look at when comparing models includes:

Check your power source

Make sure that your power source can be used with the type of pressure booster pump you are looking to purchase so that you don’t have to have an electrician wire for a higher voltage.

Housing Material

Choosing a stainless steel body housing will ensure a corrosion resistant booster pump, providing a longer lifespan

Single-stage vs Multi-stage
Multi-stage:

  • Multi-stage provides for quieter operation
  • Allows the pump to not work so hard on longer piping systems or rising elevations

Single-stage:
Galvanized tank or bladder

A galvanized tank or bladder will provide safe, potable water for use in residential capacity.

Things to Consider:

1. Flow Rate (GPM=gallons per minute):

  • The maximum flow rate is the highest achievable rate of volume that water is discharged through the pump.
  • Determine the maximum flow rate you need before making your decision.

2. Total Pressure (Head):

  • Head refers to the maximum height the pump can push the water when fighting gravity.
  • Pressure can change if the liquid's gravity changes, but the head will not.
  • Determine the total head needed for your application before making your selection of pressure booster pumps.

3. Pressure Boost:

  • The pressure boost is the highest achievable pressure that needs to be added to the current water pressure of your system.
  • The amount will be referred to in head feet or pounds per square inch (psi).
  • The difference between the system pressure and the existing water pressure will be the pressure needed with the pump.

4. Self Priming:

  • A self priming pump will create and maintain an appropriate vacuum level to pull fluid into an inlet without assistance.

5. Variable Speed:

  • A variable speed will allow the pump to be operated at various speed levels.
  • Provides for energy savings.
  • Allows the pump speed to be changed based on the needed flow of water.

Other Considerations:

  • The power source of the pumps could include AC or DC powered or magnetic drive, a magnetic drive unit is one that is assembled with permanent magnets mounted to a drive assembly on a standard electric motor.

Who Needs the Best Water Pressure Booster Pump?

The Best Water Pressure Booster Pump can be used in a multitude of applications and most people will have a use for one at one time or another. Pressure booster pumps can be used in residential, commercial, farms, apartment and commercial buildings and even for water irrigation systems. Homeowners making upgrades or renovations to their home should consider if a pressure booster pump will be needed. If larger pipes are being installed or if you are adding plumbing areas such as bathrooms or kitchens you may need a pressure booster pump. Check with your local city office before making any renovations.

Factors that Cause Low water pressure

Problem with the plumbing system

The pipes may have clogged or are leaking, which reduces the pressure of water flowing into your home. Low water pressure caused by this problem can only be resolved by inspecting and fixing your piping system.

New water fixtures additions

If you have added a new water fixture in your home such as an extra tap, it can cause a reduction in water pressure. A booster pump can fix this issue.

The water source is far

If you are located at the far end of the water supply line of your locality, then the amount of water reaching your home may be too low; hence, the reason why you are experiencing low pressure. Installing a water pressure booster pump can help you to increase the water pressure in your home.

Elevation

If your home is elevated high above the source, then you should expect to experience low-pressure water because of gravity. You will require a pressure booster pump to fix the issue.

Low pressure in your locality’s supply line

The water supplier in your region may be feeding water into the supply line with low pressure; hence, you also get low-pressure water running out of the tap. You can boost the water pressure when it reaches your home by installing a water pressure booster.

Testing Water Pressure

Its essential you check your water pressure regularly because too much pressure can affect the piping system, while too low pressure can lead to an inadequate supply of water in your home.A pressure of more than 75 psi can damage your plumbing system while that of below 30 psi can be too low.

To test the water pressure, attach a pressure gauge to an outside spigot to get the pressure readings in terms of pound per square. If the pressure is low, you can install a water pressure booster pump using the following guide.

Installing a water pressure booster pump

  • Turn off the water supply into your home at the main water supply valve.
  • Then clean the section on the main water supply line where you want to install the pressure booster pump.
  • Use a tubing cutter to cut out a section of the waterline.
  • Put up the pressure booster pump in place, then cut and fit a copper pipe to run out of the pressure booster to the main water supply. Remember to check the directional arrows to ensure you fit the booster in the appropriate ports, i.e., inlet and outlet.
  • Seal the connections by soldering them to prevent leakages.
  • Connect the booster’s pump switch to the electrical panel. If you aren’t comfortable or confident to do it, consider seeking the assistance of an electrician.
  • Turn on the water valve, and your pump should power on.

You should have a bypass in place to isolate the pump just in case it fails to ensure you continue getting water supply into your house while you troubleshoot it.

Final Verdict

Having the proper amount of water pressure can make or break a person. As you can see, all the booster pumps listed here are of good quality and performance. Their features provide for reliability, comfort and durability. We’ve outlined all the best features and provided actual user's feedback.

Making a choice between these five booster pumps is going to come down to your needs and wants. If you have minimal needs, you don’t need to purchase a pump that is more suitable for big commercial buildings. Purchasing a best water pressure booster pump that is beyond your needs is just spending money you don’t need to spend.
