just saw this on ebay, I know nothing about wfp but this seemed to be a large output of pure water,

Well, as long as your client doesn't mind you hooking up to draw from their water mains on meter, you can produce 2 litres per minute of pure water to clean their windows. 

Give them a money back refund for water useage and no probs.

Pj, is 2 litres a minute good and what would the cost be to the property owner for water taking into account it would probably be a commercial property

An interesting concept this system.

I would not want to haul that around on a trolley!, it would be better off mounted in your van all the time, and if you have a van why not fit a tank as well? Not every customer has a guaranteed high psi water outlet.

If you are going to fit a tank as well you do not really need such a fast production rate, so you could probably get away with a much cheaper Ro system.

For interest this system only produces just over 2 litres a minute, a Merlin on 100psi input pressure will produce between 2 and 3.2 litres per minute and is a lot cheaper than the above system.

Not very practical if you do mostly domestic work not everybody has out side taps and what about the noise factor from the generator
