if you are going down the DI route you will need to know the ppm reading of your water
the higher the reading the sooner you will have to change your resin
as this is the only thing that is cleaning it ( making it pure ) by the sounds you won't be using that much so may be a few months??? ;)

You can calculate it yourself. Others on here have calculated it as 500,000/TDS = no. of litres of water you would get from a 25 kilo bag. Don't treat that too literally as it can vary.

Plan A
You'll need a TDS meter to take the reading from your tap.
In the top box, enter your TDS reading.
In the next box down, put in how many litres you'll use per month - work on 2 litres per minute for first cleans but half that for next cleans.
If you're not on a meter, put a zero in the third box - or the price if you are.
Click the tab button on your keyboard to see the figures below change. The top line will say how many litres of DI water you'll get from a 25ltr bag of resin. Divide this by your monthly usage to see how long it'll last.
Plan B
Talk to another window cleaner and ask if he'll sell you some 25ltr cannisters of DI water every month
The Resin seems to last forever if it's permanently wet inside the DI vessel, if thats the simple answer you were after.
Mumble grumble, mountains, molehills . . .
