I posted on here a few weeks ago about the new Gardiner backpack I'd ordered. I have been waiting on a friend who promised me pure water from a jet engine maintenance cleaner company he works for. He finally came good today with four 25 gallon barrels full. Some were concerned on here about the quality/purity of the water and I was concerned that wfp backpack system was going to be hopeless, I glad to report we were both wrong and it is the business. I like the way the new pack has a decent integrated moulded handle which some complain about on other models and I also found the thing ok strapped on my back (although it wasn't topped right up). Really looking forward to getting out cleaning again and this £220 investment has just made my job a lot safer. My original intention was just to do the occasional dodgy window, but now I'm thinking once I've got the thing set up I might as well do all the upstairs.
