How does everyone get rid of there used resin . I usually have to dump 7 litres every couple of weeks , it was never a problem before . I would always change it while I was working usually down a custys drain or down a road drain . But now I am storing my bottles at home I will have to dump it at home . I can't use the drains in the street as I blocked two of them a few years back and the neighbours weren't impressed . So what's the best way . Straight in the wheelie bin or what .
