Good morning! First off, sorry, i know these types of questions are somewhat annoying, but i assure you that i have done TONS of youtube videos, reddit(probably a mistake), and google searches, however, for the life of me cannot figure out some of these issues. You dont have to know ALL the answers; an answer to any of these questions is greatly appreciated!
First off, prior to purchasing my machine I researched what type of machine specs would work best for sidewalks and driveways, and i found all sorts of different answers. What i gathered is that anything between 3200-4000PSI and nothing less than 3.5 gpm is what is needed to do driveway and sidewalk work, with higher range psi if im considering washing other things. Per statements like these “A 4000 PSI pressure washer is ideal for heavy equipment, concrete surfaces, brick walls, construction sites, stripping paint and lifting oil stains” I ended up purchasing a 4000psi 3.5gpm Simpson pressure washer (pw) and a 14inch surface cleaner(sc). My first question is
- Did I purchase a machine thats too strong?
After getting the machine set up and getting familiar with it, i tried it out on a few random loose objects/surfaces around the house. What i found out is 4000 psi is DEFINITELY too much for certain surfaces, but is it too much for MOST surfaces?
Did i mess up by buying the wrong machine?
Ive read lots of solutions to having too much pressure, such as loosing the pressure valve(sounds risky) and buying different SC tips, and lowering the engine throttle(i dont know). Is it even safe for the machine to not run at full throttle? The most logical thing for me, is to buy bigger tips( also i feel like this would solves the issuse of my SC trying to become a helicopter) which brings up a different question. Ive seen about 30 different charts and im only about 65% im even reading the chart right anyway, but beisdes that it seems that every chart is way different from the last! Where i live, there isnt any PW dealers by besides stores like home depot or tractor supply, and not trying to be rude but…those arnt the people i would want to ask. Do you guys have any recommendations for places to purchase tips? The only places i see when i look it up are amazon and hardware stores(home depot and lowes do not carry any)
Basically to sum up my questions, did i buy the wrong machine?
Would my machine to useful for the type of work i want to do? If not what WOULD it be good for?
Would buying different tips solves my pressure issuse and if so, where can you find them?
Thank you for taking the time to read all that and again, ANY answers are greatly appreciated. Have a great day
