Donte explained things really good earlier in the thread. Use whatever tip is going to give you the pressure you want according to the nozzle chart. Just don’t ever use a nozzle that is going to restrict your 4 gpm pump. You’re going to want to learn how to read a nozzle chart.
Let’s say you wanted to wash something using 1000 psi. Look at a nozzle chart and follow to the right until you find 1000 psi. Now go down until you come to 4 gpm (your machine gpm). Now go all the way to the left to the nozzle size. So, a #8 will give you 1000 psi.
You asked about the 3.5 nozzles. Look at the nozzle chart and run it in reverse from what we just did above. This time you’re going to follow it to your pump’s max psi. What do you think you get?
Not in my m.o. I prefer to run the snot out of mine lol. As far as setting the unloader goes when I pop a new one on my unit I just carefully dial it in to psi…say unit is rated at 4k I slowly close ball valve and make sure it doesn’t go over 4k to bypass…works like a charm and my unloader lasts a very long time. I used to set pressure with zero degree nozzle and nozzle chart and trigger gun till an old tech showed me that trick and I haven’t had any issues yet. It comes out just a little more precise for initial set up. But to each their own lol
So I have a question I am trying unit for first time I bought 10%sh mixed 6cups to a 5 gallon bucket a little weak I think. I sprayed the front of my house waited abiut10 minutes and I don’t see a difference. What am I doing wrong???
What is the draw rate of your chemical injector? At 10/1 you would be putting a 1% solution on the surface. That is plenty to clean with and won’t hurt anything
I understand now. Because I’m down streaming I don’t have to dilute the 10%. If I were using a back pack sprayer I would. Thank all of you guys for willing to help me in any way instead of just telling me to bug off.
Please don’t walk around with bleach strapped to your back. It will eventually leak due to the seals and fitting not holding up to bleach it will then leak and chemically burn you.
