A dedicated discharge would be best but not necessary. Joining the two pump discharges would be okay.
However, if your existing pump is a centrifugal (non-positive displacement like an impeller or diaphragm) pump, you'll need a check valve to prevent the water from flowing through the old pump. I recommend a Bosworth flapper style check valve. https://www.thebosworthco.com/products/selectv.php?category=C -- Dennis C.
