Introduction :How to Increase Water Pressure in a Shower

Dealing with low water pressure in your shower can significantly diminish the quality of your bathing experience.

Understanding how to increase water pressure in a shower is essential for a rejuvenating and efficient shower.

This guide offers practical solutions to enhance your shower's water pressure, turning a mundane routine into an invigorating experience.

How to Improve Water Pressure in the Shower

Common Causes of Low Water Pressure

Before diving into solutions, let's understand what might be causing low water pressure in your shower. Identifying the root cause can help you choose the most appropriate solution. Common reasons for low water pressure include:

  1. Old or Clogged Pipes: Over time, pipes can accumulate sediment and mineral deposits, reducing water flow.

  2. Flow Restrictors: Some showerheads come with built-in flow restrictors to save water. While eco-friendly, these restrictors can decrease water pressure.

  3. Shut-off Valves: If the shut-off valves leading to your shower are partially closed or obstructed, it can limit water flow.

  4. Supply Line Size: Older homes may have undersized supply pipes, restricting the amount of water reaching your shower.

  5. Water Saving Showerheads: Modern showerheads designed to conserve water can also reduce water pressure.

  6. Pressure from the Mains: If your home is far from the municipal water source, it may experience lower water pressure.

How to Measure Your Current Water Pressure

Before making any changes, it's essential to determine your current water pressure. You can easily test it using a simple method:

  1. Gather Your Tools: You'll need a measuring jug, a timer, and a calculator.

  2. Place the Jug: Position a 1-litre measuring jug under the showerhead.

  3. Turn on the Shower: Set the shower to its maximum flow rate.

  4. Start Timing: As soon as the water starts flowing into the jug, start the timer.

  5. Stop Timing: When the jug is full, stop the timer.

  6. Calculate: Divide 1 by the number of seconds it took to fill the jug. If it takes more than 6 seconds, you likely have low water pressure.

DIY Methods to Increase Water Pressure in a Shower

Now, let's explore some do-it-yourself methods to boost water pressure in your shower. These are relatively simple fixes that can make a noticeable difference.

1.Cleaning Your Showerhead:

  1. Sediment and mineral buildup can clog your showerhead.

  2. Remove the showerhead and soak it in vinegar to dissolve deposits.

  3. Scrub away any remaining particles with a brush.


Over time, mineral deposits and sediment can accumulate in your showerhead, obstructing water flow.

To address this, remove the showerhead and soak it in a bowl of vinegar for several hours. This will help dissolve the deposits.

After soaking, use a soft-bristle brush and a toothpick to remove any remaining particles from the individual spray openings.

Reinstall the showerhead, and you should notice an improvement in water pressure.


  • Improved water pressure.

  • Cost-effective.

  • DIY-friendly.


  • Temporary solution.

  • May not work for severe clogs.

  • Requires periodic maintenance.

2.Checking and Replacing Pipes:

  1. Old or corroded pipes can impede water flow.

  2. Inspect your plumbing for signs of damage or rust.

  3. Replace any damaged or aging pipes to improve water pressure.


Examine the pipes leading to your shower for signs of corrosion or damage.

Older houses may have iron piping that is vulnerable to rusting, which can break off and obstruct the pipe.

If you find issues, consider replacing the affected pipes.

This can be a significant improvement, especially in homes with aging plumbing systems.


  • Effective for old or corroded pipes.

  • Permanent solution.

  • Customizable to your needs.


  • Costly.

  • Requires professional installation.

  • Can be disruptive to your home.

3.Adjusting the Shower Valve:

  1. The shower valve can impact water pressure.

  2. Ensure the valve is fully open.

  3. Contact a plumber if the valve is damaged.


Check the shower valve, usually located under the kitchen sink, to ensure it is fully open. If it's partially closed or obstructed, it can limit water flow.

If the valve appears damaged or you're unsure about its condition, it's advisable to contact a plumber for an inspection. A properly functioning valve is crucial for maintaining adequate water pressure.


  • Immediate impact on water pressure.

  • Often a simple adjustment.

  • Minimal cost.


  • Limited to cases where the valve is the issue.

  • Requires some plumbing knowledge.

  • Not a solution for all low-pressure problems.

4.Removing Flow Restrictors:

  1. Some showerheads have flow restrictors.

  2. Consult the showerhead manual to locate and remove the restrictor.

  3. Be aware that removing the restrictor may increase water consumption.


Modern showerheads often come equipped with flow restrictors to reduce water usage. While this is environmentally friendly, it can result in reduced water pressure.

Check your showerhead's manual for instructions on locating and removing the flow restrictor. Keep in mind that removing it may lead to higher water consumption.


  • Immediate increase in water pressure.

  • DIY-friendly with simple removal.

  • No cost involved.


  • May lead to higher water consumption.

  • May void warranties on some showerheads.

  • Not suitable for eco-conscious users.

Upgrading Your Plumbing System

If the DIY methods don't provide the desired results or if you're looking for a more substantial improvement in water pressure, consider upgrading your plumbing system. Here are some options:

1.Installing a Shower Pump:

  1. A shower pump can significantly boost water pressure.

  2. It works by increasing the force of water before it reaches the shower.

  3. Consult a plumber for proper installation.


A shower pump is a mechanical device that can be added to your home water system.

When you turn on the shower, the pump activates and boosts the water pressure as it flows to the showerhead.

However, it's essential to note that adding a shower pump directly to mains water pressure is illegal, as it can damage the plumbing.

 In most cases, a break tank is required for proper installation. Consult a plumber for installation and choose a reliable pump brand like Grundfos, Stuart Turner, or Salamander for optimal results.

2.Upgrading Water Lines:

  1. Old or undersized water lines can limit water pressure.

  2. Consult a plumber about replacing the plumbing lines throughout your house.

  3. This can be a costly renovation project but may significantly improve water pressure.


Older water lines can accumulate mineral deposits and restrict water flow. Upgrading the plumbing lines in your home, especially if they are old or undersized, can be a substantial improvement. Consult a plumber to discuss the options and costs associated with replacing the plumbing lines. While it can be a significant investment, the result is often a consistent and improved water pressure throughout your home.

The Cost of Increasing Water Pressure

The cost of increasing water pressure in your shower can vary depending on the method you choose and the extent of the required changes. Here are some cost estimates for different approaches:

  • Cleaning Your Showerhead: £5 - £10 (DIY)

  • Replacing the Shower Head: £30 - £50 (DIY or professional)

  • Installing a Shower Pump: £150 - £500 (DIY or professional)

  • Upgrading to Larger Water Lines: Costs vary, contact a plumber
