Pressure washer question
Bill, I suspect the term ""flooded to 75 psi" is a result of literally translating something from an Asian language into English with no regard for grammar.
I believe they mean it must be supplied with water, at a pressure of up to 75 psi. The inlet pressure has nothing to do with outlet pressure.
The volume of water is the only crtitical factor, if the pump output is 4 gpm, then you must be able to supply that much to it, or it will cavitate.
We routinely supply ours with either a trash pump or tank. If it's a tank feed we keep the tank up on the truck and put the pressure washer on the ground behind it to allow the head of water to help gravity a little.
BTW, unless you have a big tank, don't get fussy about getting stuff perfectly clean, a decent sized pressure washer can go through a lot of water fast!!
Best of luck.

Pressure washer question
Sounds like a simple enough question.
Put the barrel in the truck with a 5 gallon (for a margin of safety) under the drain line and see if the pail fills in less than 60 seconds....
Sounds marginally more exciting than watching grass grow.  .
BTW, the intake hose will not be sucked flat or collapse on a pressure washer if you use a garden hose, the plastic or rubber is stiff enough on a hose of that diameter to prevent it. But you do need to be carefull that it is not kinked, since there will be no pressure to the water to force itself past it.
If you're concerened about it, you can always rig up an air line to pressurize the water tank to help push the water to the pump, or elevate the tank higher, water weighs 8.34 pounds, so every foot you can raise it will be a big help.
est of luck.

I suspect it has more to do, as I said earlier, about flow rates than pressures.
A "standard" garden hose will not flow 4gpm at or near 0psi, the cavitation is not because of a lack of pressure, merely a lack of adequate volume RESULTING from a lack of pressure.
Best of luck.

Pressure washer question
Mark, if you have some room in your attic you should consider installing a tank up there. A friend did this years ago, he lives in a rural area and loses power for a few hours regularly.
Basically it is like a huge toilet tank, when the water drops below the set point, which is only after the power goes out and some water has been used, and there is power to the well pump, the tank tops itself off, IE right after a power failure so it's ready for the next one. When there is no electricity, all he has to do is open a second valve behind his toilet to allow the water to flow down by gravity into the toilet tank.
It is not the normal full pressure, so it doesn't flush like normal, but it beats starting the genset, or carrying buckets of water.
It doesn't take much of a tank to flush a modern low-flow toilet a bunch of times!!
Best of luck.

Pressure washer question
Mark, based on the issues I have with my pool, and being at 45° north lattitude, I can tell you, you will not like the amount required to 'sterilize' standing water.
Your best bet is to consult a pool supply company which is where you will get the cheapest supply of chlorine anyways. Since Household Bleach is 5 1/4% Sodium Hypochlorite, Liquid Pool Chlorine is 12 1/2% Sodium Hypochlorite.
I'll try not to make this a chemistry dissertation, but here goes. Pool chlorine is 12% sodium hypochlorite, which also can be expressed as 120,000 parts per million (PPM). Household bleach is approximately 5% or 50,000 ppm. In order to sterilze water for safe use in a pool you need about 6000 ppm. If you diluted pool chlorine, 1 part of bleach to 19 parts of pure water, you would end up with solution strength of 6000 ppm. In order to sterilze water for safe use in a pool you need about 6000 ppm.
For drinking water you would want way less than that, but for storage of water, not being potable water, that would be a good starting point.
Best of luck.
Best of luck.

Pressure washer question
Or use that # 46 B/H and bury a tank in the yard where the water will stay cold enough to retard the algae growth in the first place.
Ann is right about the level of chlorine in potable water.
However I know from experience that 6,000 ppm does not kill my grass or the apple trees when they get soaked on a regular basis. I'm pretty sure that much would make you clean as a whistle inside & out though if you drank it. .
Best of luck.
