All our house downpipes & stormwater pipes lead into a water tank and the whole system is known under the name of "charged system".
We will have a new pergola built and need to handle the stormwater. We are wondering if it's OK to connect the new gutter into the existing downpipe / charged system. Obviously, the cut/join into the DP would be well above the tank height, but what about the charged system? Would it be disrupted so that it stops functioning correctly? Is the pressure in the system (or something else) going to be stuffed (technical term )??
