what sort of money am i looking at for a backpack set up inc pole etc and all that is needed to produce a qty of pure water

itll surely pay for itself over a few months and even better if its stops me killing myself  by over stretching

[mark dew]

It will pay for itself pretty quickly just by the extra money from windows above conservatories on your existing work.

rcs the window cleaning warehouse backpack will be fine.
Any ro that produces 100 gallons per day or more with a booster pump, a rain water butt, water containers, your backpack + plus pole and you are away.  
The pole would be your most expensive single item. A 25ft pole would cover most domestic work.

here is a list of what you need to start with.
Windowcleaningwarehouse is a good place to price up the above.

That's very good. You have bought wisely i reckon. Where from?
rcs, this setup is fantastic for the price. Add a booster pump to this kit and you have a very efficient ro. Almost halving the production time with purer water as well.
The above is the benchmark i think. That is a wise investment.
All he needs is water tank, cleantech pumpbox and reel of hose and he has everything.

Get the best pole you can afford and build around that. A harris pole will let you work cheaply, but compared to carbon fibre poles they are crap. Same as glass fibre poles.
Buy carbon, buy well and reap the rewards from day 1.
A good pole will save you loads of time per day. With few if any, aches and pains over the long term.
