pressure washer vs power washer image
Steven
I plan to buy a high pressure 250psi spray nozzle which I will put a link in the end. But I want to know if I bought only a 5/8 inch hose, will that limit the water pressure. I just went to the store and saw that 5/8 inch hose is actually quite thin haha. Should I cancel my order and buy a bigger 3/4 inch hose or is the 5/8 inch just fine? Thans

Answer
Most household water pressure falls between 60 -80 PSi, with some getting as high as 100 PSI.
Unless you have an unusually high pressure pump or supply source, virtually all common GHT nozzles will handle your service.
Garden Hose is usually rated for between 150 PSI and 250 PSI Maximum Allowable Working Pressure (MAWP).
There are commercial hose products that utilize long shank commercial GHT (Garden Hose Thread) couplings that might be able to exceed 250 PSI MAWP, but would not be likely to be found in your situation.
There are special nozzles, used in the Fire Equipment Industry, that are capable of handling higher pressures, but these are so expensive as to be absurd for your use.
You cannot get more pressure out of the system than goes into it.
When you restrict the flow at the nozzle outlet, by using a smaller orifice (outlet hole) you minimize the pressure drop that occurs and you will have the effect of more force, but at the expense of REDUCED FLOW.
Dixon Valve's "Adjust-a-Power" Nozzle is used by forest firefighters to achieve better reach and minimize water usage. It is also widely used as a "sweeper" nozzle for removing debris.

Short of getting a real pressure washer, or getting a special nozzle that requires an air compressor to boost the pressure from you hose, this is the best thing for "hitting" power, but it will not let you put out the volume of water a regular Garden hose nozzle will.
Nelson is a fine company, however realize that the "300% more water flow than a standard nozzle" is ONLY possible when you have the 250 PSI pressure at the nozzle inlet. The increase is mostly due to the higher flow rate at 250 PSI vs 100 PSI.
Putting a high volume nozzle on a smaller diameter hose will somewhat starve the nozzle, resulting in a reduced outlet pressure, and "hitting" power of the stream.
If a high flow rate is your requirement then you should go with the 3/4" Hose.
If you opt for a lower volume nozzle then the 5/8" hose might suffice.
Make sure which ever hose you get is rated for the applications working pressure.

Steam washer vs traditional high pressure washer ?
I'm planning on doing mobile car washing in Los Angeles ca but don't know if to go with the steamer washer or high pressure water.. Will going with the steamer caused swirls?? Or it's safe if properly use? So tell me go with the traditional high pressure washer or steam cleaner??
Answer
One thing you might want to look at is the price difference, pressure washers are pretty cheap and steam cleaners need a way to heat the water, I guess you would probably be using propane and that set up is not cheap at all, Do you really need steam to wash a car?most guys I see just use gas powered pressure washers I pay a guy 20.00 and he does a great job, good luck with your biz
