I have a 3800 psi dewalt pressure washer and im wanting to turn it down to about 3000-3300 psi but im not sure to tell what psi im at while turning the pressure down.
If anyone could help me out id appreciate it!
Thanks!
Answer
What you would have to do is connect a pressure gauge between the end of the hose and the gun. Run the pressure washer with the gun's trigger pressed so there's water flow and check the pressure it is shooting water. To adjust it to the pressure you want you can either use the unloader to regulate pressure or adjust the engine's rotation which would also regulate pressure.
If you need a gauge here is the link to a 5000 psi one. There are more on the website in case you think this one is too much.

Please explain how pressure washer work and its pressure generating principle.How big psi can 12V can generate

I am looking for a pressure pump(washer) that generates 1500-5000 psi applying 12V DC battery. How many batteries required ?
Can I buy such pumps in the market ? please give more information on it.

My pressure washer has a 5 horsepower motor and creates about 200 psi. The short answer is that car starter motors create 5 to 10 hp for a short while but get hot fast. One battery will do the job for a very short while. The easier way is to use an electric washer, convert the 12 vdc to 120vAC with an inverter and wash away. The amount of batteries will depend on how long you want to operate at high pressure. The more the better. Can you buy such a pump, sure, convert a small home electric unit. Another good source for this stuff is West Marine, check their website and they have a great tech staff and no I don't work there.
