Hi All, I have a dilemma. Replace the long "torpedo" shaped LPG tank that feeds all the appliances (Warm Air/Hot Water/Oven and Fridge) or go down the Gaslow route. The Gaslow's would be arranged as a pair. Can you get level meters (remote) for them ?Does the t connector have to have a non-return valve in it?Do they do an auto changeover? Many thanks for any Pros and Cons you might have.:thumb: Steve.
