Do Quick-Connects Restrict Water Flow?

Machine Repairs

Probably silly question, but at what point do the amount of QC’s begin to restrict water flow? 1? 2? 5? If so, is the restriction minimal?

I’m trying to streamline everything, but don’t want to end up sacrificing flow for convenience. I have a 4.5gpm Landa Belt-Drive. Mostly residential work, (primarily cleaning to prep for paint, plus decks, fences & the occasional driveway).

Troy with a 4.5 gpm machine, you don’t have to worry about restrictions. unless you are using a 1/4" hose.

Great question!! 4.5 gpm you have nothing to worry about.

As for me I always wondered this question when it comes to high GPM. I have machines that are 8.5gpm - 10.5gpm. Sometimes we’ll even combine 2 machines to get 17gpm. The hoses I have range between 3/8" & 1/2". I always wondered when we run let’s say 5-100’ sections of hoses with quick connects in the middle, how much restriction do they cause.

Have you ever done a draw-down test?

Thank you for taking the time to reply. With as many views as my question got without a reply, I was beginning to think it was a stupid question. I’ve read through pretty much every thread on this site and couldn’t find the answer, but I didn’t know if that was because the answer was so obvious that nobody was dumb enough to ask. I appreciate your feedback.

Yes but only with a 100’section of hose and never with quick connects except the ones from the ball valve and the ones on this one section of hose.

It would be cool (though probably time consuming) to see how much each section and/or QC affected the flow.

What kind of flow did you get with the 100’ section?

Thank you Ralph. That’s good to know.

Pretty much what the pump rating was. I never did this though with 2 machines tied together or with longer then 1 section of hose.
