In my world im trying to make Zombified Piglin gold farm. That requires turning a 23 x 23 nether portal with a flint and steel dispenser and a water dispenser for completing this mechanic. I got the fire part down but there is an issue with the water dispenser. It wont remove the water when the redstone signal turn off. To conserve flint and steel durability, I'm making the entire portal manual by flicking a lever on to activate and deactivate the portal once.
What answer I'm looking for
I want to figure out how turn the water on and off with just one redstone signal just after the F&S dispenser activates the portal (activate and deactivate the portal when a redstone signal is recieved).
