redstone interacting with blocks doesn't seem to work for me

So this is the whole block listener java file. I'm sorry if this is a dumb question as this is my second java and bukkit project. The idea of the plugin being that when a player right clicks a block it turns a fence block into a water block (this works) I also want it to be triggered by redstone.

Code:

package me.sman.Dam;

import java.awt.JobAttributes.SidesType;
import org.bukkit.ChatColor;
import org.bukkit.Material;
import org.bukkit.World;
import org.bukkit.block.Block;
import org.bukkit.entity.Player;
import org.bukkit.event.block.BlockPlaceEvent;
import org.bukkit.event.block.BlockListener;
import org.bukkit.event.block.BlockRedstoneEvent;
import org.bukkit.event.block.BlockRightClickEvent;

public class DamBlockListener extends BlockListener {
    public static Dam plugin;

    public DamBlockListener(Dam instance){
        plugin = instance;
    }
    public void onBlockRightClick(BlockRightClickEvent event){
        Block block = event.getBlock();
        Player player = event.getPlayer();
        Block water = block.getRelative(0, 1, 0);
        int w = 85;
        if(block.getType() == Material.MOSSY_COBBLESTONE && plugin.enabled(player) && water.getType() == Material.FENCE){
            player.sendMessage(ChatColor.BLUE + "Dam Open.");
            w = 8;
        }else{ if(block.getType() == Material.MOSSY_COBBLESTONE && water.getType() == Material.WATER){
            w = 85;
            }
        }
        if(block.getType() == Material.MOSSY_COBBLESTONE && water.getTypeId() == 8 || block.getType() == Material.MOSSY_COBBLESTONE && water.getTypeId() == 85 || block.getType() == Material.MOSSY_COBBLESTONE && water.getTypeId() == 9){
            water.setTypeId(w);
        }
    }

**this is the part that is faulty**

    public void onBlockRedstoneChange(BlockRedstoneEvent event){
        int x = event.getBlock().getX();
        int y = event.getBlock().getY();
        int z = event.getBlock().getZ();
        Block water = null;
        int w = 85;
        if(event.getBlock().getWorld().getBlockAt(x+1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.FENCE){
            water = event.getBlock().getWorld().getBlockAt(x+1,y+1,z);
            w = 8;
    }else{ if(event.getBlock().getWorld().getBlockAt(x+1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.WATER){
            water = event.getBlock().getWorld().getBlockAt(x+1,y+1,z);
            w = 85;
        }
        }
 
        if(event.getBlock().getWorld().getBlockAt(x-1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.FENCE){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 8;
        }else{ if(event.getBlock().getWorld().getBlockAt(x-1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.WATER){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 85;
        }
        }
 
        if(event.getBlock().getWorld().getBlockAt(x,y,z+1).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.FENCE){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 8;
        }else{ if(event.getBlock().getWorld().getBlockAt(x-1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.WATER){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 85;
        }
        }
 
        if(event.getBlock().getWorld().getBlockAt(x,y,z-1).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.FENCE){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 8;
        }else{ if(event.getBlock().getWorld().getBlockAt(x-1,y,z).getType() == Material.MOSSY_COBBLESTONE && event.getBlock().getWorld().getBlockAt(x+1,y+1,z).getType() == Material.WATER){
            water = event.getBlock().getWorld().getBlockAt(x-1,y+1,z);
            w = 85;
        }
        }

        if(water.getType() == Material.WATER || water.getType() == Material.FENCE){
            water.setTypeId(w);
        }
    }
}

 

Might want to compare your materials like so:

water.getType().equals(Material.WATER)
