hi all I would very much welcome any suggestions or advice as to what water tank I should consider buying. I'm a sole trader and so far have been filling up 25 litre jerry cans at the end of each day. As I'm getting busier I think it's about time to buy a water tank to put in my garden. I was thinking about getting a 300 or 350 litres water tank ( or should I go for a bigger tank? not sure whether going for a flat or an upright one? best place to buy it ? many thanks
