How do I increase the water pressure from a hose?


When you want to clean things around your house, water is a necessity. If you need a little bit of water, you can use a bucket. If you want to clean a larger area, a hose is much more convenient. The higher the pressure from your hose, the easier the job will be. It means you can cover a larger area, or you can remove more tough stains.

How do I increase the water pressure from a hose:

In general, to increase the water pressure from a hose, I recommend using a shorter and wider hose. This way, the water will experience less resistance. Also, ensure that the hose and connections are clean and not leaking. To further increase the pressure at the faucet, you can use an additional water pump.

This blog will provide you with methods and tips to increase the water pressure from a hose. I also look at some common problems that lead to a decreased water pressure.

Increasing the water pressure from a hose, some helpful tips

There are several ways to increase the water pressure from a hose. The first is to check and fix any issues with your hose. Minimize bends. Use a shorter and wider hose, and replace the nozzle with a high-power one.

● Method 1: Check and fixing problems with the hose to increase the water pressure

If you would like to improve the water pressure from a hose, the first step is to check the condition of your hose.

– Step 1: Check for leaks in the hose

A leaking hose is one of the most common problems that will decrease the water pressure. To find leaks, lay the hose flat on the ground. Check along with the hose for any points from which the water might be leaking. These leaks can be tiny, so you must inspect carefully, and if a leak is detected, repair the hose with a rubber patching kit.

– Step 2: Check for the connection of the hose with the spigot and nozzle

Check for any leaks where the nozzle is connected to the hose. And where the hose is connected to the spigot. The water pressure can drop due to an improper connection. Check the hose connections on both ends and look for any blockage preventing a smooth water flow. Make sure to check the connections across the splitters as well if you are using any. Tighten all the connections.

– Step 3: Look for the twists in the hose

A straight hose has the least water resistance. Tight bents and corners will lower the output pressure. Try to straighten the hose as much as possible. And in case of bends, make them as wide as possible.

– Step 4: Clean the hose

If there are no leaks in the hose or at the connections, check for dirt inside the hose. To clean the hose, submerge it in the bucket filled with water and ¼ cup of bleach solution. Let the hose sit in the bucket for 8 hours. Afterward, place the hose in plain water and spray out any loose leftover dirt.

● Method 2: Using a shorter and bigger hose to increase the output pressure

If you want to increase the water pressure from a hose, you can decrease the length and increase the size. Water that flows through a hose will have resistance. A 3/4″ hose will see a decrease of around 2 PSI per 100 ft. A 5/8″ hose will see a 4 PSI decrease. And a 1/2″ hose will lose 13 PSI per 100 ft. This means that when the faucet delivers a pressure of 30 PSI, a 1/2″ 100 ft hose will only have 17 PSI when it reaches the end of the hose. If you shorten and widen the hose to 3/4″ and 50 ft, you will have 29 PSI at the hose end. That is almost 60% more pressure.

● Method 3: Using a high-powered nozzle to increase the output pressure

If your water pressure is low, but you still would like to have a high output pressure from your nozzle, you need to use a different nozzle. Using a high-powered nozzle with the hose can increase the output pressure significantly. It will reach longer and makes some jobs much more comfortable. These nozzles come with a long, thin tube and concentrate the water to increase the pressure.

● Method 4: Installing a water pump

Water pressure from a hose can also be increased by installing a water pump. This method is an alternative to the nozzle method and can increase the water pressure at the beginning of the hose. A water pump connects to an outlet, and a hose is attached to the pump. This method will be explained in more detail in the next part of the blog.

How do I increase the water pressure outside? Some helpful tips

Increasing the outside water pressure can be achieved using several methods. 

Low water supply pressure affects the ability to clean outdoor areas effectively. Low water pressure in outside areas can be increased by installing a water pump, proper hose extension, or rain harvesting system.

● Measure the current water pressure

Before starting to try to increase your water pressure, it is a good idea to measure the current pressure first. Use a pressure gauge for this. Place it near the main valve where water enters your home or at your outside faucet. If the gauge shows a reading of less than 20 PSI, then your water supply pressure is low. To increase the pressure, there are several methods we will now further explain.

● Install a water pump

The best way to increase the water pressure outside is to install a water pump. You can install a pump to increase the overall pressure in your house. Or only to increase the pressure for your outside faucet(s). There are many types of pumps available in the market. For increasing the outside water pressure, a regular pump will do the job.

You can add the pump between the faucet and the hose. Most pumps will come with a water pressure regulator that allows you to regulate the pressure according to your choice.

● Improve the pipes going to the outside faucet.

Shorter and wider pipes will increase the output pressure at the faucet. A 3/4″ pipe will see a decrease of around 2 PSI per 100 ft. A 5/8″ pipe will see a 4 PSI decrease. For a 1/2″ pipe, it is even 13 PSI. This means that using a wider pipe will decrease the pressure loss in the pipes. Where possible, try to have the shortest route to the faucet. Shorter and wider increases the pressure.

When the water pressure that goes to your outside faucet has a pressure of 30 PSI at the start. Using a 1/2″ 100 ft pipe will lower the pressure to 17 PSI when it reaches the end of the hose. If you shorten and widen the hose to 3/4″ and 50 ft, you will have 29 PSI at the end of the pipe. That is almost 60% more pressure.

How do you fix low water pressure outside? Some helpful tips

If the water pressure at your outside faucet is lower than expected, there can be several things you need to do. First, check the faucet and pipes leading to the faucet for any blocage. Some areas have a lot of minerals in the water that can build up over time. If you use a hose, check this as well for any blocage. Second, check if the lower pressure is due to the time of day or always present. Finally, check the main valve and pressure regulator.

The following are some of the common problems that decrease outside water pressure.

● Outside Tap:

Low water pressure can be due to a faulty outdoor faucet. Pressure drops if the facet is old or leaking. Slight blockage in the pipes or faucet itself can also decrease the water pressure significantly. The minerals in the water can form build-up or clog in the faucet, which hinders the water flow. Remove the tap and clean it.

● Outside hose:

If you have connected a hose to the faucet, it can be the culprit. It might be dirty, entangled, cracked, or leaking. This can reduce the pressure of the water flowing through it. However, water may not reach the end of the hose effectively, so repairing the leak or worn parts of the hose or installing a new one can fix this problem. 

If your hose is not damaged, low water pressure can be due to the attachment at the end of the hose. Therefore, replace the attachment with a high-pressure spray one. Another way to increase the pressure at the end of your hose is to use a shorter and wider hose. And ensure there are the least amount of curves.

● The water demand in your neighborhood:

The causes of low water pressure may not always be in or around your house. High water demand in your neighborhood can affect this as well. For example, when all irrigation systems start working in the morning. Or people take a shower around the same time before going to work. It will impact the water pressure. Generally, the water demand is higher in the morning and the evening. Therefore, I recommended checking the water pressure several times and see whether low pressure is due to high water demand.

● The problem in the main valve:

People often make a common mistake of not turning the main valve fully open. This reduces the water pressure in your house and on any outside faucet. Checking is easy. Locate the main water supply valve in your house and ensure that it is not damaged and is fully open.

● Water Pressure Regulator:

Low water pressure can also be due to poor water pressure regulator adjustment, also known as the pressure-reducing valve. The water pressure regulator is often located along your main stopcock. Measure the pressure with a pressure gauge nearest to the water regulator and see if there is something wrong with it. Some can be adjusted to increase the pressure. Generally, a PSI between 40 to 60 is considered good water pressure. Anything below 30 PSI means the pressure is low.

Will a smaller hose increase water pressure?

In general, a smaller hose will increase the water pressure. The smaller the pipe, the more resistance the water will see. A 3/4″ hose will see a decrease of around 2 PSI per 100 ft. A 5/8″ hose will see a 4 PSI decrease. For a 1/2″ hose, it is even 13 PSI. Besides a higher pressure, a smaller hose will see a lower flow rate. The flow rate is the amount of water that can go through the hose. For a hose, this will be measured in Gallons per Minute (GPM).

Will increasing the pipe size increase the water pressure?

In general, with increased pipe size, the water pressure will decrease, and the flow rate will increase. The advantage of a larger pipe will be less water resistance. A 3/4″ pipe will see a decrease of around 2 PSI per 100 ft. A 5/8″ pipe will see a 4 PSI decrease. For a 1/2″ pipe, it is even 13 PSI.

Increasing the pipe size allows for more water to flow through the pipe, thus increasing the flow rate.
