Sorry mate.
Look its really simple.
To work with water fed pole you need:
A means of obtaining pure water.
Three ways of doing this:
Buy from me:
DI..This is a cylinder filled with resin,you hook a water supply to it,water goes in one end then comes out of other end pure.Problem is resin costs £70ish for 25ltrs which in our area (poor water) will only last a couple of months.
RO:Initial outlay is bigger as I said my Merlin cost £300ish,however thats it,attach the ro to your water supply and it comes out of the other end (slower than DI but you produce it at home for next day)pure.No resin to buy every few weeks.The membranes and filters will need changing every now and again (which wont be often if like me you only wfp upstairs).
Thats the water sorted:
Now you need a means of getting the water to the windows:
We use a trolley (omnitrolley) we also have a van mount but only use this on commercials.
You put the water in the trolley and the trolley pumps the water to your pole and onto the glass.
The pole simply connects to the trolley with a good old fashioned hozelock fitting.
Loads of places you can get poles from but mine are from Gardinerpolesystems.co.uk
I would recommend going for 24ft pole rather than 18ft as this gives you the option of cleaning the high windows above conservatories (its a real stretch with 18ft).
There ya go mate any questions I will answer when ya come round next week.
