The most common garden hose size is the standard garden hose with a diameter of 3/4 inches, but you might consider investing in a larger size such as an inch or 1 ¼ inch when using a pressure washer.
When the water from the pressure washer enters your garden hose, it needs more room to flow through than when just watering your plants with a hose.
In order to make sure that there’s enough space for this increased water flow, you need a wider opening at one end of the hose which means going up in size.
If you want to be able to increase your spray distance without any drop in pressure then you will also need a longer length of hose that can accommodate this increase in water flow. If you’ve got all the equipment but your garden hose is holding you back, go for a larger one.
A garden hose with a diameter of 1 ¼ inches can handle up to 2000 PSI so it will be able to handle almost any pressure washer out there without letting it kill your plants or blow up your neighborhood.It is also flexible enough that it won’t kink as you use it.
A garden hose with a diameter of an inch can handle up to 1500 PSI. This is good for higher-end pressure washers, but if the pressure washer is more low end then it will still be able to handle it just fine.Still, this size gives you a good amount of distance and flexibility without being too kink-prone.
These sizes have been used for years but if you still feel the need to go bigger there is a garden hose with a diameter of 3/4 inches that can handle up to 500 PSI. Just remember that it won’t have the same flexibility or resistance to kinking.
It is also important to remember that if your pressure washer is going to be stored outside out in the sun then you’ll want a garden hose with UV protection.
There are many different hose lengths and diameters to choose from, but here is a breakdown of the most common ones:
3/4-inch garden hose
This size garden hose is used for everything like watering plants, washing cars, and filling kiddie pools. These are standard hoses that are easy to find and affordable.
– hose length: 25 to 100 feet.
– garden hose diameter: 3/4 inches.
1-inch garden hose
This size of garden hose has more pressure than the standard 3/4 inch because it can withstand up to 80 PSI, but this means that you need an increased water flow which is why you need a larger hose diameter.
– hose length: 25 to 100 feet.
– garden hose diameter: 1 inch.
1 ¼ inch garden hose
This size is the largest garden hose that you will find and it allows for a much stronger flow than 3/4 inch or 1-inch hoses.
This size works best when you want to completely saturate an area with water in order to clean out dirt instead of just spraying it around.
There are limited standard lengths of 1 ¼ inch garden hose which makes them a little harder to find.
– hose length: unknown.
– garden hose diameter: 1 ¼ inches.
Conclusion
The most common garden hose size is 3/4 inches in diameter, but if you are using a pressure washer to clean your driveway or patio then it would be worth investing in an inch or 1 ¼-inch garden hose.
Overall, the best size garden hose to use with a pressure washer is 1 ¼ inches because it allows for the strongest water flow without any loss of power.
