Water, as you probably know, is essential for plant growth. It is the desire of every farmer to have a farm or garden that reeks of health, lusciousness, and beauty, and the right amount of water using the right water hose is the secret to achieving that.
Water hoses are the farmer’s ally when it comes to watering of plants, and they come in different lengths appropriate for various watering needs. Plants are very delicate and even something as essential as water, when given in “too much” or “too little” proportion, can have severe effects on growth.
For the plants to get the appropriate amount of water required for growth, a water hose with the appropriate length will be needed. It will also help to put into consideration the flow rate of the hose before deciding on the one that will be adequate for your needs.
What Is Water Pressure?
Water doesn’t just come out through pipes or hoses on its own. There is a force that pushes the water through the hose, and that force is known as water pressure.
Without pressure, water would not come out when you turn on your tap or even when you connect your hose to a water source to water your plants.
It is possible to measure the pressure of water, and the unit of measurement is in bars. Using this measurement, you can know the amount of pressure needed to transfer water from your water source, through the hose, to your garden.
Do you also know that farms or gardens on hilltops will receive higher water pressure than the ones on the foot of a hill? This is because it takes a lot more energy to push water uphill, but water will naturally run downhill with little pressure.
Water pressure is dynamic and can change if it is measured at different times of the day. This also means that the amount of pressure exerted by water on the hose can be affected by the time of the day you chose to use the hose.
What Is The Water Flow Rate?
Flow rate is simply the quantity of water that goes through a hose each minute. The flow rate is usually expressed in gallons per minute or GPM in abbreviation. The water flow rate of a hose will go a long way in determining the amount of time it will take for a quantity of water to pass through the hose.
So many factors are put into consideration in determining the flow rate of a hose. Some of the factors include the length of the hose, the level of water pressure, the depth of the water vessel as well as the diameter of the hose.
Is Water Pressure The Same As Water Flow Rate?
I know by now you may be wondering if water pressure and flow rate are the same, but they are not. If they are not the same thing, then what is the difference?
While water pressure tells you the amount of force that is put in to make water move through the hose or pipe, the flow rate of water helps you to know the gallons of water you should expect from the hose per minute. So you can’t really talk about water pressure without talking about the flow rate.
What Is The Flow Rate Of A Garden Hose?
One of the most crucial tasks facing a Gardner is choosing the right garden hose that will aid the efficient and effective watering of the plants.
Most garden hoses come in different lengths and diameter, which affects the quantity of water flowing through the host per minute. However, the flow rate of a garden hose is between 9 to 12 gallons of water per minute.
A typical garden hose will have an average water flow rate of 12 to 13 gallons per minute. Though this, to a large extent, depends on the type of hose used. So, the garden hose to use will, therefore, depend on the watering need of the plants.
Things That Affects Water Pressure
Nothing is more pleasurable than watering your plants with a hose that is the right fit for the job. Since water pressure has a lot to do with how much water gets to your plants through the hose, we will look at some factors which affect water pressure.
The diameter of a hose is a major factor that affects water pressure. Most garden hoses have diameters of 3/4, 1/2, and 5/8 inches. The garden hose you are currently making use of probably has one of these dimensions.
If the inner diameter of the hose is large, more pressure will be created, but if it is narrow, low pressure will be created.
No one would ordinarily choose a garden hose that is not long enough to reach the destination intended. However, you must remember that the length of a hose affects the water flow rate as well as the water pressure.
You may not need to qualify as a rocket scientist before understanding that water pressure reduces when using a longer hose and increases when you make use of a shorter hose.
When you move water from a long distance, the water pressure will be affected as well as the flow rate.
How Do You Determine Water Pressure
The most obvious way to get this done is to use a water pressure gauge. This is how it works:
- After purchasing a pressure gauge, screw the pressure gauge to your water faucet (not all pressure gauges can do this, so look for one that can be screwed).
- After that, turn your water on. You should see the pressure gauge reading.
- Measure the reading. Whatever you get eventually is your water pressure.
How Do I Increase Water Pressure In My Hose?
Low water pressure could be caused by a variety of things. To remedy this, you can take the following measures:
#1. Check for Leaks
This is usually the first place to start. A leaking pipe will invariably lead to reduced pressure. You can check for this by turning off all the faucets in your home and every other appliance that consumes water.
Check out for your water meter. If you find it spinning and running even after putting off everything, then most likely, you have a leak. If you can fix this, your water pressure is sure to increase.
#2. Fix Clogged Pipes
If you don’t have leak issues, the next culprit to check out for is this. A clogged supply line will noticeably temper down your water pressure. This is usually the case with old pipes. Rust and corrosion can cause your pipe to become clogged.
You might not have to worry about this bit if you’re using PEX or PVC lines. But if you have galvanized supply pipes, then this is something to watch out for.
#3. Properly Connect Your Hose
Another thing that could reduce your water pressure is this. Check to see that your hose is properly connected to the nozzle and spigot. If you see water leaking from the nozzle section, that could be an indicator of a poor connection. Simply watch out for leaks and go ahead to tighten such.
#4. Twisted Hose
As simple as this sounds, it could actually be what’s causing your water pressure to go down. While you work, ensure your hose stays straight. If you discover that it has all of a sudden become bunched up, don’t fret, just straighten it and continue working.
#5. Adjust the Pressure Regulator
If you’ve done all of the above and you’re still experiencing the same issue, then it might be time to visit your water pressure regulator. This is usually close to where the water meter is. If your pressure gauge gives off a low reading, simply adjust the regulator by giving it a clockwise turn.
If you’re making a very large adjustment, it might be best to conduct your plumber first as old pipes can be strained while trying to do this.
#6. Visit a Professional
If after doing all of these nothing changes, then it’s probably best to get professional help. This should get the job done without any stress on you.
A variety of things can cause water pressure to be affected. Top amongst the list could be the length of your pipe. The trade-off is this, longer pipes work well for ease and convenience, but you might have to accept the fact that the longer the hose, the lower the flow rate and water pressure.
