How to Increase Your Low Shower Pressure

How to Increase Your Low Shower Pressure?

The shower with higher pressure will make your showering experience better also reduce your shower time.

So, here we will discuss some methods which will help you to increase the water pressure of your shower.

Required Tools and Materials


  • New Shower Head
  • Toothpick

Tools/ Equipment

  • Timer or stopwatch
  • Five-gallon bucket


1. Testing the Shower Head’s Flow

Testing the Shower Head’s Flow

First of all, you need to turn the shower on to full capacity and wait for a minute. Now put a 5-gallon bucket under the shower and record the time of filling the bucket.

Now you have to calculate the GPM and for that, you need to divide the time taken to fill the bucket by 5. For example, if your shower takes 2.5 minutes to fill the bucket, the GPM will be 2 (5/2.5). The standard benchmark of GPM flow is:

  • 2.5 GPM: the legal maximum flow of the US for all the showerheads
  • 2 GPM: the current standard of the US WaterSense
  • 1.5 GPM: the standard rate of water flow from the low-flow shower

2. Replacing the Water-confined Shower Head

If there is any integrated water-confined device or shower filter in your rain shower head it can minimize the water flow from your shower head. So, you can increase the water flow by simply removing the water filter or water-confined device.

Also, you can replace your shower head with a higher flow model. However, before changing your current shower head you need to make sure that the new shower head is legal in your locality.

For example, in California due to the states drought issue, the GPM of the shower heads has come down to 1.5 GPM from 1.5 GPM.

3. Removing the Scale and Clogs

The mineral deposits and build scale in the showerhead over time and for a heavier flow from your shower head the time to time removal of the scale is necessary.

You need to unscrew the showerhead and submerge it in white vinegar for a minimum of 8 hours. Now take a toothpick and clean any residual particle out from each of the spray openings.

Reinstall the showerhead and check out if the water is flowing in full force or not. If it is not possible to remove the particles, you need to buy a new showerhead.

4. Turning the Curb-Side Shutoff Full On

Shutoff Full On Shower Head

If the curb sided main shut off is slightly turned off it may decrease the water pressure of your showerhead. The shutoff can be off for several reasons such as not turning it on fully after construction work in your home.

You can turn the curb-side shutoff on by turning the round handle counterclockwise. If there is a level handle the handle should be at the level of the water pipe to flow the water in full motion.

However, the civilians cannot interfere in the curb-site shutoff so you need to call your water supplier to make any change in the shutoff.

5. Checking the Main Shutoff

The main shutoff of your home can be the reason for the lower water force in your shower head. If the shutoff is not fully on it can reduce the water flow from the showerhead.

There can be several reasons such as your previous house owner may have intentionally turned the water volume down to save water or due to construction or water leakage.

Now you have to turn the round handle of the shutoff counterclockwise or level the level type handle to the water pipe to turn the shutoff full on. If the valve is rusty or corroded don’t force it and go for professional help.

6. Replacing the Volume Valve System

The single-handle faucet of the shower or the valve system influences the water pressure of the shower to a great extent. So you need to check out and replace the volume valve if required.

This is an expensive and complicated part and over time you need to change it to get the maximum water flow from your showerhead. This part is difficult and pricey to repair so it is better to replace it.

7. Opening the Inline Shutoff

If you have an inline shutoff valve on the water supplying a line of the showerhead it can impact the water flow of your shower head.

You can turn off the water supply of a specific area such as sink, toilet, shower, etc. in an emergency with the help of these shutoff valves.

You may find these shutoff valves near the water supply point (if you have any). If the inline shutoff valve is not fully open it can restrict the water flow from the showerhead. So turn the valve counterclockwise to enjoy the full water pressure from your showerhead.

Hopefully, following the above instructions will help you to increase the water flow from your showerhead and allow you to have an enjoyable shower
