I've just fitted temporary 250litre tank in the back of my van, until I have a custom one made.
However, the thing I noticed was that the pressure of the jet coming out the brush was significantly higher than when using a 25litre barrel.
This remained high until the level the tank dropped to around a 1/4 full, and I could tell the pressure had backed off to what I'm used to.
This isn't really a problem, as I can contoll the flow rate from my hose valve.
But I figure I'm going to be using more water than I expected.
Has anybody else experienced this?
Thanks
Marc
