When a drain return modulating valve is not present, it is important that the drain return is restricted (the valve is partially closed). Otherwise, flow from the drain will potentially prevent adequate flow from the gutter return. In an ideal case, the surge tank should always have a modulating valve on the drain return. | When a drain return modulating valve is not present, it is important that the drain return is restricted (the valve is partially closed).
