ok once again im turning to the collective minds of indy,for answers.ok i work for some people who have 2 tanks of 10,000 litres each side by side.the old fella has alziemers and emptied one by leaving on a hose,the other one is full,ok heres the problem,ive cleaned off the roof and tested it by putting a hose on it,the water went off the roof and eventually started flowing into the tank,you beauty i thought,but after about 20ml of rain on the weekend theres nothing in it,i for the life of me cant work it out.anyone willing to throw some scenarios at me please to help,also it flows down a pipe under the footpath and flows up the pipe to get into the tank,when i put the hose in the roof ,im trying to work out how the trickle i put on the roof manages to travel up then in
