How do mobile valeters with on board water use pressure washers - don't pressure washers run from a tap?

Question

Is there enough pressure going into the pressure washer from a static tank to run it ?

Thanks.

Answer 1

Pressure washers will draw from any source of water, it doesn't need a "head". I frequently run mine from a bucket. It uses surprisingly little, one bucket will both wet down and rinse off. Most mobile valeters just drop the intake pipe (a bit of hose) into a jerrican of water in the back of the van, the "posher" ones will have a tank built in.

Answer 2

the pumps on pressure washers do not care where the water comes from, as long as there is enough for the flow it is set at. whether from an on board tank or somewhat pressuruzed from a water tap, the engine drives the pump, which put out water at some predetermined CFM rate (cubic feet per minute). If I understood the question correctly. Good luck!

Answer 3

They usually use a gas powered pressure washer and a large water tank or tap off a garden hose---a water source is all that's needed.

Answer 4

valeters isn't in any dictionary I found - even on dictionary.com. So let's assume you mean a mobile car wash.

Pressure washers run from WATER.

So if someone has a minivan and a pressure washer, they have a tank for water in the minivan.
