I've got just about everything I need now to have a go at WFP. I plan on starting out doing top windows only and see how I get on. I'll be practicing on my own house, friends houses and a select few customers houses before I go at it properly. I've got my backpack, pole and hose and I found a decent sack barrow last night when I was out collecting so that's saved me a few quid. I bought a small second hand tank so I'm all good there. I need to get hold of a few more drums but that won't be hard. I'm going to order some ubik too. Am I missing anything else? I've got a few other questions too. I'll be buying my water. How long will it stay pure? If I filled up with water and went on holiday would it still be good to use when I get back? The tank I bought was previously used to store pure water. I take it I can just fill it up and don't need to worry about cleaning it? If I filled my backpack with tap water to do a job that didn't require pure water, is it ok to fill it with pure water after or do I need to clean it first? I'll probably have a few more questions at some point. Thanks for the help so far.
