How do I make everything stop if the player stops touching it?

I'm making a bucket/water system where the player can pick up water into their bucket by clicking "E". I want it to be that if the player leaves the water as in they stop touching it, then they can no longer pick up water. I'm not sure how I can implement something like that.

Finds if Player Touched

local Water = script.Parent
local Remote = game.ReplicatedStorage.InWater
local Players = game:GetService("Players")
local Pos = Players:GetPlayers()
local deb = false

Water.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild("Humanoid") ~= nil then
   if deb == true then return end
   local deb = true
   local Ch = hit.Parent
   print(Ch.Name)
   local Player = Players:FindFirstChild(Ch.Name)
   Remote:FireClient(Player)
   print("Remote Fired")
   end
   wait(3)
   deb = false
end)

Snippet of Local Script that finds if Player clicked E

Remote.OnClientEvent:Connect(function()
     if Character.Bucket ~= nil then
        Character.Bucket.IsInWater.Value = true
        print(Character.Name.." Connected!")
        PlayerGui:WaitForChild("Water").Enabled = true
        UIS.InputBegan:Connect(function(input, proc)
           if not proc and input.KeyCode == Enum.KeyCode.E then
             local Water = Character.Bucket:GetChildren()
             for i,v in pairs(Water) do
                if v:IsA("Part") and v.Name == "Water1" and v.Visible.Value == false then
                    FirstLoad:FireServer(Player)
                    print("One Dip")
                    break
                elseif v:IsA("Part") and v.Name == "Water2" and v.Visible.Value == false then
                   SecondLoad:FireServer(Player)
                   print("Two Dips")
                   break
                elseif v:IsA("Part") and v.Name == "Water3" and v.Visible.Value == false then
                   ThirdLoad:FireServer(Player)
                   print("Three Dips")
                   break
                end
           end
        end
        end)
     end
end)
