I ran some numbers once (my day job is a engineer) and I came out with: you only need about 4" of head to get a flow rate out of a barrel of about 5 gpm. (Which is the min. required for most pressure washers that are small to medium sized.)
@09rja that is some cool information! Good to know I should be just fine with the barrel in the bed of the truck. Thanks for watching and sharing. ~Mr. C.
@@NaturesCadenceFarm You are welcome. But those pressure washer manuals also say the flow needs to be delivered at 20-35 psi. I don't know if I buy that. That is nearly 20 feet of head. If they needed that much, nobody could run off of a gravity tank. Anyway, I am just now getting into pressure washing. (I have a bunch of uprooted stumps I am going to blow the dirt off of to get them to a more manageable size.) So we'll see how it goes.
@09rja yea I am not buying the higher than barrel psi on the input either. It works great with as little as 3 feet of head. I have been doing this for years with the same pressure washer. That's a good idea to use the pressure washer to remove dirt. Thanks for sharing. ~Mr. C.
@@NaturesCadenceFarm Just a update: my set up didn't work. What happened was: there was too much head loss between the tank and the washer because of the 15' of hose between the two. I didn't run the numbers on that head loss (originally) because I thought it was minimal......turns out you can lose 25' of head in 100' of hose. So I am looking into booster pumps now because I have to have (at least) 15' of hose between the tank and the washer.
@09rja that stinks. Thanks for the update. I understand what you are saying about the the resistance induced on the water as it flows in the longer hose. I guess I have been using very short hoses and have not experienced that phenomenon. Great information. If you don't mind, keep me posted. ~Mr. C.
@joelbennett3840 thanks! With fairly consistent use I got around 20 minutes which was plenty for what I was doing. Specs for the pump say 2.5 gpm. Thanks for watching and commenting. ~Mr. C.
@bigr0075 that is cool. I thought it would be helpful for others to see. I tell people at work about this and all of them thought the inlet needs to be under pressure. I love being able to be mobile with this setup. Thanks for watching and sharing. ~Mr. C.

Great video! How quickly will the pressure washer empty the rain barrel?

How much flow does your pressure washer have, and how big is your water supply??
Use this setup on our farm equipment out in the Fields
