Looking for advice for best / safest way to plumb a waveline dc pump which has a barbed output adapter. The male threads on the pump output aren't compatible with standrd Pvc so can't hard plumb it. Want to avoid any chance of flex tubing blowing off at connection points at the pump output and at the bulkhead leading to return to display. Not sure I can trust plastic clamps to hold the flex line attached. Thanks for the suggestions.
