Yes, you can increase well water pressure, but the method depends on what's causing the low pressure

Low pressure from a well usually comes from one of three places: the pump itself is undersized or failing, the pressure tank has lost its air charge, or sediment is clogging the system. You can address each one. A larger or newer pump will move more water. Recharging the pressure tank costs almost nothing. Flushing the lines or replacing a filter removes blockages. The fix you need depends on what's actually wrong, and that usually means checking the pump and tank first before spending money on replacement parts.

If you have a submersible pump (the most common type in residential wells), it sits inside the well itself and pushes water up to your house. If you have a jet pump, it sits above ground and pulls water from the well. Both can be upgraded, but the cost and effort are different. A submersible pump replacement typically runs $1,500 to $3,000 installed. A jet pump replacement is usually $800 to $2,000. Before you replace anything, though, rule out the cheaper fixes.

Key Takeaways

  • A waterlogged pressure tank — one that has lost its air charge — is the most common cause of low pressure and costs $20 to $50 to fix by recharging it yourself.
  • Sediment buildup in your well, pump intake, or filter can choke flow; flushing the system or replacing the filter often restores pressure without replacing the pump.
  • If your pump is more than 15 years old or cannot maintain pressure even after the tank and filter are serviced, it may be undersized for your household's water use.
  • A pressure tank that is truly failed (rusted through, cracked, or unable to hold air) must be replaced; a new tank costs $300 to $800 installed.
  • Upgrading to a larger pump or adding a second pump can increase pressure permanently, but this is the most expensive option and should be your last step.

Check and recharge your pressure tank first

The pressure tank stores water under air pressure so that your pump does not run every time you turn on a faucet. Over time, the air charge inside the tank leaks out or gets absorbed into the water, leaving the tank waterlogged. When this happens, the pump has to work harder and pressure drops. This is the single most common reason for low pressure, and it is also the cheapest to fix.

To check the tank, turn off the pump at the breaker and drain the system by opening a faucet. Then use a tire gauge to check the air pressure in the tank's valve — it is usually a small black or brass fitting at the top. Most residential tanks should read between 28 and 40 pounds per square inch (PSI), depending on your system. If it reads zero or very low, the tank needs air. You can add it yourself with a bicycle pump or air compressor, or call a well service to do it. The cost to have it done is usually $75 to $150.

If the tank holds air for a few weeks and then loses it again, the tank's internal bladder or diaphragm has failed and the tank must be replaced. If the tank is rusted, dented, or leaking water, replacement is also necessary. A new pressure tank costs $300 to $800 installed, depending on size.

Clean or replace your well filter and intake screen

Sediment, sand, and mineral buildup can clog the filter that protects your pump and the intake screen at the bottom of the well. When this happens, water cannot flow freely, and pressure drops. If your water looks cloudy or has a sandy taste, sediment is likely the problem.

Check your filter first. Most homes have a sediment filter somewhere between the well and the pressure tank — it looks like a white or blue cartridge in a clear housing. If it is brown, tan, or visibly dirty, replace it. A replacement cartridge costs $15 to $40 and takes 10 minutes to swap out. If the filter is clean but pressure is still low, the intake screen at the bottom of the well may be clogged. This requires a well service to pull the pump and clean or replace the screen, which typically costs $300 to $600.

You can also flush the entire system to clear minor sediment buildup. Turn off the pump, open the lowest faucet in your house (usually a basement or outdoor spigot), and let water run until it runs clear. This removes loose sediment from the lines without taking apart the well.

Inspect the pump for age and capacity

A pump that is more than 15 years old may straightforward be worn out. Even if it still runs, the internal impeller can wear down, reducing flow and pressure. If your pump is this old and pressure remains low after you have recharged the tank and cleaned the filter, replacement is likely the next step.

You should also consider whether your pump is sized correctly for your household. A pump rated for 5 gallons per minute (GPM) will struggle if your home uses 8 GPM when multiple faucets run at once. If you have added bathrooms, a hot tub, or irrigation since the pump was installed, the original pump may be undersized. A well service can measure your actual flow rate and tell you whether a larger pump would help.

Pump replacement is the most expensive single fix — $1,500 to $3,000 for a submersible pump, $800 to $2,000 for a jet pump, including labor. But if the pump is old and the tank and filter are already clean, it is usually the right choice.

Add a booster pump for permanent pressure increase

If your well pump is working correctly but pressure is straightforward lower than you want, a booster pump can increase it. A booster pump sits between your pressure tank and your house and adds extra pressure to the water as it flows through. This is useful if your well naturally produces lower pressure or if you want higher pressure for a shower or irrigation system.

A booster pump costs $400 to $1,200 installed and uses electricity to run, so it will add to your power bill. It is most practical if your main pump is in good condition and you just want more pressure, rather than as a fix for a failing pump. Some homeowners use a booster pump to serve only one part of the house — for example, a shower or outdoor faucet — rather than boosting pressure everywhere.

Have a well service test your system

If you are unsure where the problem is, a well service can test your pump, tank, and lines in about an hour. They will measure your water pressure at different points, check the tank air charge, inspect the pump for wear, and look for leaks. The cost is usually $150 to $300 for a service call and inspection. This is money well spent if it saves you from replacing a pump that is not actually the problem.

When you call, ask whether they can do the inspection the same day or if there is a wait. Some areas have well services that can come within 24 hours; others may take a week or more. If pressure is very low and you need water for basic use, mention that when you call — some services prioritize urgent cases.

Frequently Asked Questions

How do I know if my pressure tank is waterlogged?

Turn off the pump, drain the system by opening a faucet, and use a tire gauge on the air valve at the top of the tank. If it reads zero or very low (below 20 PSI), the tank is waterlogged. You can also listen — a waterlogged tank often makes a hissing sound when you turn on a faucet because the pump cycles on and off rapidly.

Can low water pressure damage my pump?

Not directly, but a pump that runs constantly because the pressure tank is failing will wear out faster. If your pump cycles on and off every few seconds, have the tank checked right away. Constant cycling can shorten the pump's life by several years.

What is normal water pressure for a well?

Most well systems are set to maintain 40 to 60 PSI. Anything below 30 PSI usually feels noticeably weak for showers and washing. If you want to know your current pressure, a pressure gauge costs $10 to $20 at a hardware store and screws onto any outdoor faucet.

Will a bigger pump always give me more pressure?

A bigger pump will move more water, but pressure is controlled by your pressure tank and switch settings, not just pump size. A larger pump is useful if you want more flow — for example, to run multiple showers at once — but if your tank and switch are set for 40 PSI, a new pump will still deliver 40 PSI, just more of it.

How often should I have my well system serviced?

Most well services recommend an inspection every two to three years. At minimum, have the system checked if you notice a change in pressure, water quality, or how often the pump cycles. Regular checks catch problems like a failing tank or clogged filter before they become expensive.
