I know this is a weird topic here on the S&W site but I thought you guys might know. I need to buy a new pressure washer hose. Currently it has a cheapo 1/4"x25' hose. I want something longer so I figured I would need a bigger diameter hose. On my old washer I used an extension hose (also 1/4") and that caused a noticeable drop in pressure and water flow. Web sites I have checked have claimed the drop should be minimal, but it was very definitely noticeable. My washer is pretty small. It only has 1700psi to begin with. I like it's lower pressure since I don't destroy as much but I can't afford any further pressure drops. Have any of you guys ever replace your pressure hose with a longer one. How did things go? How flexible was it? I don't want a hose so heavy that I hate using it. I was thinking about a 5/16"x50' or a 3/8"x50'.

Check out Harbor Freight. They might have something. Problem is, if you get a different size hose, the pressure may not be the same. If you are losing pressure, it could be something else you need to work on.

Have always used a 1/4inch 50ft hose on my Honda GC190 power washer. 6HP 2.7gpm and 2700psi.

I found this online:

"The Science of Hose Lengths
Assuming a best-case scenario – working on flat ground and normal operating conditions – you typically won't lose much pressure as you increase the length of hose that you use. For instance, on a 3/8-inch hose with a 3 gallon/minute flow, the loss of pressure per 100 feet is about 50 PSI."



I think the water hose you use for your input makes more difference than the output hose. Long cheap water hoses that collapse easily are a royal pain when using a power washer.

A couple of years ago my hose busted and I took a chance on one of the Flexzilla hoses, glad I did. Very flexible and easy to work with.

I sold pressure washers for over 40 years.
Go with the 3/8”
👍👍

I have a 100 foot garden hose made by that company. Pretty strong and light as a feather.

My little 1600psi electric power washer came with a kinda plastic hose that wants to stay coiled all the time. I'd like to try the one you linked to if I knew it would fit my little Ryobi washer.

Pretty sure the connections are all standard, you should be fine.

Why do you need longer than 25 ft?


Move the washer closer to where you need to work they are on wheels

Use a 100 ft supply hose or whatever

I've never used a power washer with a hose longer than 25 foot.

I want to add that I have a two-story house and trying to clean it using a 25ft hose is a real pain. Also, the easier it is to do the job the more likely I am to start the job. I only have one faucet that I can connect my garden hose to. That means I sometimes have to run the hose through my house to get the washer where I need it. A 50ft hose will eliminate that problem. By the way, thanks to everyone for the reply's.

My question was for the OP not you.He has now answered why. He wants to get up to a 2 story house.
