HELP!!!! we tried to fit our toilet today, go the old one out and on puting together the toilet system we found we had no re fill tube or clip supplied We had it since December last year and havn't fitted as has been busy elsewhere and although we checked our bathroom order didn't think to check the sealed bag with the toilet system... does anyone know what diameter and length this re fill tube is or where we could get one without having to buy the system parts again please..
