I just recently bought a j rod that’s rated for 2-3 GPM machines. It says it can reach up to 15 feet. Do y’all think I will be able to knock out a smallish 2 story house with that and maybe a ladder?
You could probably hit the gutter hard enough on a 2 story to clean it but you probably have to go very slow, with a step ladder you could definitely hit it.
You should be fine applying chem to the siding even on a second story DSing With that set up. Just going to be slower
I’m assuming you’re a diy homeowner. Nobody knows what you’re house looks like. A two story house can mean very different things. If you have a ladder you will Ben fine. Remember to dilute your bleach as small machines pull at a much higher rate.
Also this probably isn’t the best forum for a do it yourselfer.
I’m not a diy homeowner I’m actually just starting out a pressure washing business. Got my first house wash job and I was making sure I could knock a few house wash jobs out with a 2.8 gpm before I upgrade. I didn’t know I needed to dilute it because it’s a smaller machine. With 12% SH how much water would you say I need to mix? Thanks
I’m honestly not sure. I would mix 2 gal bleach to 3 gal water. Then increase or decrease strength if needed.
Good chart. Easy to read

To better answer your question what type of material are you cleaning? Vinyl siding, brick, hardi board? In general a 1% strength mix is used with a downstream injector pulling from a chemical tank which is combined with your water after the pump.
Yes you can. I started with a simpson 2800 psi, 2.8 gpm and it works. Just get the right tips (M5 twist nozzle rated for 2-3 gpm and you will get it) when youre gonna hate it is when you gotta surface clean. If you get anything more than a 16 inch you will be going REAL slow.

Best to test before putting on the side of someone’s home. If using the built in bleach container on the PW. Fill and then use your soap nozzle to fill fill a 5 gallon bucket. Use that to determine how much liquid was removed from the built in tank and that will give you an accurate mixing ratio and you can go from there. For example, the big box craftsman I had would pull at a 12:1 ratio with the soap nozzle. If I used 12.5 SH, that would equate to roughly a 1% SH end result. Lots of folks on this board with much greater understanding of the ratios than me…but I had that same question less than a month ago and that is the process I used to figure out my mixing ratio.
I’m washing vinyl. I plan on just putting the SH in a 5 gal bucket and drawing from there. So I guess I should put 1 gal of bleach in at first and then spray it all into 5 gal buckets until the bleach is gone to see my ratios? So like if I do that and it fills 2 5 gal buckets before the bleach is all gone I’ll have a 10:1 ratio is that right? Then I look at the chart and mix for the 10:1 ratio? Thanks for all the help I really appreciate it trying to learn as much as I can.

It’s really easier to just start with 1:3 ratio. If the algae turns brown in 2-3 minutes, you’re at the sweet spot. Adjust accordingly.

To measure your ratios from two containers use water, no need to waste chemicals. You can still measure how quickly the water is gone.
