Wondering if any of you sump users are using ball valves on your return line? If so, any problems?
Ok but do I really need one if I'm not worried about the return line flow rate? Or are they beneficial for other reasons?
You dont really need one if you're worried about return pump flow rate. I do not like check valves, so I use one incase there is a power outage and i need to stop water from siphoning into my sump from my tank.
