How Much Water A Garden Hose Use – Learn All About Hose Flow Rate And Water Pressure

Wondering how much water a garden hose use? Passionate gardeners and homeowners would want to understand this, to maximize efficiency and effectiveness in providing the correct quantity of water to their plants.

It is also necessary to note the flow rate of the hose, this is to understand the adequacy of the hose, to suit your requirements. Garden hoses are essential tools to have around as it lightens the load of watering tasks, saving you time.

Let’s go through a few questions and answers about a garden hose flow rate to grasp a better understanding of how it works. I can assure you after doing this exercise you will know all there is to know about flow rates, which is essential for your plant’s water provisions and other household uses.

What Is A Garden Hose Flow Rate

In order to establish how much water a garden hose use, we must first understand what is flow rate. Basically, the simplest definition of what flow rate is is the quantity of water that is passed through the garden hose every minute. This quantity is often shown to us in GPM ( gallons per minute).

Once gallons per minute or GPM is established, then you can also begin to determine how much water per hour is being passed through your garden hose. Countless variables contribute to the flow rate of a garden hose. These include the hose length, water pressure, and diameter.

The flow rate of a general garden hose is around 9 to 17 gallons per minute. While between 12 to 13 gallons could be your GPM reading if you are using an average garden hose. However, this calculation will vary depending on what type of garden hose you choose to use.

How to Determine Garden Hose Water Pressure

The hoses that are most commonly obtainable from retailers come with a PSI rating. Water pressure is one of the key components in determining how much water a garden hose use.

PSI means pounds per square inch which basically gives you an indication of the momentum or how fast the water is being passed through the hose. In most cases, the PSI begins from 40 to 60 and can go up to as high as 80 PSI.

The PSI of your water connection in a home must first be established as this will enable you to precisely project the flow rate of your garden hose. Also, water pressure and flow rate can increase or decrease depending on the length of your hose, as the longer the hose the more reduced the flow rate.

How Much Water a Garden Hose Use

To accurately determine how much water a garden hose use, you will need to calculate the flow rate. This can be done with a physical apparatus that includes a container and stopwatch.

However, the most effective way is to make use of the garden flow rate calculator that is available online. By logging in your data, you can establish an almost precise flow rate. You also have the option to calculate it manually.

Manual calculations are easy to establish how much water your hose uses. By filling up a bucket of water while timing it for a minute, you will get an accurate answer. For instance, if it takes you one minute to fill a nine-gallon bucket then you know that your hose uses that many gallons per minute.

How Hose Length and Width Affect a Garden Hose Flow Rate

It is not an intricate exercise to understand that the flow rate decreases if you use a longer hose. When water is being moved over a large distance, the decrease in flow rate can be drastic.

 How many gallons of water per minute does a garden hose use?

Here are a few pointers for you to consider:

A hose that is about 25 inches in length can have a flow rate of 24 GPM as the diameter and PSI will determine this.
If we are to join a few of the hoses together or use a longer hose, say a 100-inch hose, then the flow rate dramatically drops by 75 percent.
Also, the shorter the hose the better it is to effectively water your plants as the flow rate will increase.
The diameter of the hose also contributes to the flow rate.
The diameter measurements of 1/2, 5/8, and 3/4 inches are the most regular and commonly available.

So, to fully understand how much water a garden hose use, we must understand that the diameter plays a very important role. The smaller the diameter the less GPM will be transported. When you used a smaller hose, the amount of water that is delivered to your garden is very minimal within a minute or an hour.


So, remember when deciding what garden hose to purchase, the effectiveness will also depend on the size and how frequently you use your hose for watering. If your garden does not soak in water efficiently and it stands for a while, a lower flow rate hose will be the best option.

Because water absorption is slow this reduction will allow you to use less water at a slower flow rate. However, if your garden soil absorbs the water faster, a higher flow rate hose is required. This will ensure that you invest less time watering your garden as the pace of completing the task will be reduced. Therefore, knowing how much water a garden hose use is important.

Also, if you are using your garden hose with a sprinkler attached to it, this will create an effect on the amount of water that’s being transported to your garden per hour. Gardening will become much more enjoyable when you actually begin to understand things like flow rate and learn about the efficiency of your hose.
