We have a garden pond that we top up from the tap. I know that if I had a water butt under the downspout of the house I could fit a diverter onto the downspout to direct some of the rain water into the water butt. If I were to to connect the diverter to the pond hose instead of a water butt would this allow just a small percentage of the rainwater, in a storm, to the pond whilst the rest goes into the drain. I don't want to flush the pond out in a heavy rainfall event!
