Hey I was wondering if anyone know if I have to install a one way check valve on my return pump? I’m hard plumbing the system and My outlets sit below the water line and I don’t know if it will try to “back flow” if the power to the pump shuts off. Thanks I’m advance if anyone has any input!

Here is a picture of my return pump with the check valve installed...it’s kinda bulky and don’t want to use it if I don’t have to...
