I am very new to this. We’ve moved to a house that has a pond. It uses a Creekstone 264gph submersible pond pump that has stopped several time and was dismantled & cleaned well. It has a stainless steal pin that’s a bit beat up. What I’d like to know is could I I go up in power with a Creekstone 620gph submersible pond pump which has an inline flow control valve. Or is there something better out there for me? Thanks for any assistance.
