Hello
Post a schematic.
Yes, Always show us a good schematic of your proposed circuit.
Show us a good image of your ‘actual’ wiring.
Give links to components.
Post links to "Technical information" on your hardware devices. How much current does the pump require. How does it start etc. Are you experienced in working with mains power, if not is someone experienced helping you?
