How to add collection sound to watering can?

I would like to add a sound effect when the watering can is collected in the game. It is a health pick up as well.

I've tried looking up different code but none of it works. Any help would be welcome The code for the watering can (health pick up) is below...The sound effect I wish to use is called 'wateringCanCollected' and is in Unity already, but I don't know how to add it to the script

using UnityEngine; using System.Collections;

public class AddHealthToPlayer : MonoBehaviour {

 int HealthPack = 10;// Amount player health will go up by. 

 // Use this for initialization
 void Start()
 {
  

 }
 // Update is called once per frame
 void Update()
 {
 }
 void OnTriggerEnter2D(Collider2D other)
 {
     if (other.gameObject.tag == "Player")
     {

         CharacterManager.Instance.characterData.health += HealthPack;//Update player health when watering can is picked up

         if (CharacterManager.Instance.characterData.health > CharacterManager.Instance.MaxHealth) CharacterManager.Instance.characterData.health = CharacterManager.Instance.MaxHealth;//Check if health is at maximum when player picks up watering can, keep health at MaxHealth
   
         Destroy(gameObject);//Watering can will disappear if player runs into it

         print(CharacterManager.Instance.characterData.health);//Print player health
     }//if

 }//OnTriggerEnter2D

  

}//AddHealthToPlayer
