3/4 inch softwash hose?

1

I’m getting a 24 volt 10gpm 100psi pump that has a 3/4 inch in and out. Currently using 1/2 inch hose on my 5.5 12 volt. Has anyone ever used 3/4 inch hose for softwashing? I wonder if it would be too heavy and/or not flexible enough for dragging around. Also, where could I find 200 feet of 3/4 hose that is flexible? Thanks guys, I appreciate it.

No way……too heavy. The 5/8” I think is heavy but that’s what I’d recommend.

What kind of 24v pump puts that out?

The 24 volt is a Northstar. Just want to get the biggest bang out of it possible since it has a 3/4 output. Has anyone ever used a 3/4 inch softwash hose? I know it will be too heavy for a roof, but figured I could snap on a 50 foot 5/8th at the end of the 3/4 when I have to get on a roof.

You already have 1/2” try it and see if you like it. 5/8 would be plenty big enough. You can buy 250’ roll of flexilla on amazon. I just switched to 5/8 and I’m disappointed I didn’t get any extra flow so I’ll probably switch back to 1/2 at some point

If your using a 5 or 7 gpm pump you won’t see much measurable difference in the two hoses.

I’ll be moving up to a 24 volt 10 gpm 100 psi. My understanding is that especially with these lower psi’s hose size makes a big difference. Hose size is less of an issue in pressure washers because the psi is so much greater. Is my thinking correct?

I may be way off here because i never see any talk of anyone using anything larger than 5/8" softwash hose.

Short answer, use 1/2" or 5/8". Don’t use 3/4".

Here you go:

You will see diminishing returns for hose larger than 5/8” on a 12v pump. You will have a larger volume of liquid to push after the pump, so I wouldn’t be surprised if you actually lost some flow rate by going with 3/4”.

I don’t think 3/4” hose would make sense unless you had a something more powerful than a 24v, like either air diaphragm or a gas powered system, and you were pushing 12+ gpm of actual flow. (Your 24v 10gpm pump will be doing good to push 5-7 gpm of actual flow.)

All great info. Thanks guys.

Hi Peter!! So did you end up using a 5/8 hose or your original 1/2 hose! Thanks
