  1. Your wiring is very messy. Keep the 120V water pump wires as far away from the other wires as possible.

  2. The capacitors in your snubber networks need to be rated at 120VAC or more. Either connect the snubber directly across the water pump, close to the pump (but not submerged obviously!), or across the 2 relay contacts that you have wires connected to.
