Hi,How to draw a pipe layout . The case is "a Pump pumps in water from a underground tank to a tank on a building". Now as in water cad we insert a tank on the building and connect it to a pump and inturn connects to the U/G tank. BUT we have to provide the min, max levels in the tank properties. But the actual thing is we are just filling that tank which has a demand of 5000 litres. So how can we simmulate this on water cad? I hope you understand the scenario.
