Applying Chemicals

[Harold Brantley]

MontiJ, With a little more psi it will take a little larger nozzle size to draw chemical, but I haven't tried 3.5k psi so I don't know what to recommend to you.

Greg, Great to here from you! Glad to hear someone has been doing the same thing and having success with it. I'm sure it is good for rinsing if you put your chemical hose in the water tank to get a low pressure rinse. You can also just disconnect the hose from the chemical tank and let it draw a little air in with the rinse water. Usually to lower the rinse water pressure, I just go to the size 10 or 15 nozzles that keeps the pressure high enough to stop chemical draw. Have you tried the 0 deg, size 20 nozzle to apply chemicals higher up?

Hi Harold ive seen from other posts you have written you like to exsp. with things. I like that keeps things advancing. im a x-jet fan because it was a no brainer[buy it and it works]
Can you give me a stating point for a 4.8 gal 3500 psi unit? yesterday i saw a guy cleaning a set of 3 story condos with PISTOLS [2 ft. long][I THINK HE HAD A HIGH hp MOTOR AND BIG gpm PUMP] any ideas for that ive got a 20 hp briggs ive been wanting to use for a machine just to wash buildings and houses? maybe to run 2 surface cleaners at the same time but i dont have a tank yet or a way to pull that much water.
it sure would be nice to make up 1 20 gal batch of house wash insted of 4 five gal. jugs
i would prob. use the QD tips for applying and just use the x-jet for rinse with a dual lance because that works best for me.[STUBBERN] thanks

Ron, You would need a larger nozzle size, maybe 25 or 30. It could even be that the 20 would draw chemical. If you can get a 0 deg in each of these sizes, you'll find out real quick which ones work as a chemical nozzle and which ones are rinse nozzles for your specs.

I don't understand why you would want to use the x-jet as a rinse nozzle. Just use a 0 deg in a size somewhat smaller than what you find as the correct chemical nozzle.

When you use the dual lance, remember that when you open the side valve that you will be making the nozzle size larger.

so if i have this right im looking for a 0025 and a 0030 tip?
i wash trucks with a 4055

Ron, the 4055 tells you that at a 55 size nozzle you get chemical. You just need to find out how small you can go and still get chemical draw. You might try 25 first, then adjust depending on the results. Any degree nozzle will work for the trials. Good luck.

By the sq ft., or by the job is fine, but what it all comes down to is how much are you PROFITING per hour. Find the method for estimating that gives you that answer in the most effecient way. Sometimes I eyeball jobs, and sometimes I measure, it just depends on the size, and/or how familar you are with scope of what needs to be done. You'll find that down the road, when you get used to seeing the same types of houses, drives, pool decks, etc., you can usually estimate them very accuratly by simply taking a slow walk around the house.
