Hi, this my first post, my name is Mike have been trad for 12 years in and around the Buckinghamshire area. I am considering a slow change to WFP without too much cost. This is what i would like to do and with anyones help and advice put me right lol. Trolley system and to purify a DI vessel as i will only be doing tops on selected properties to start off, so i wouldn't need a massive amount of pure water to start. Is this a feasible way to start by just trying it out at low cost end. Thnx in advance for your comments.
