I would not count on it! You may be able to dilute your urine enough so that any THC or any THC metabolites don't show up, but you will be told your urine is too dilute and made to take the test over. Use a product like The Extra Stuff, The Liquid Stuff or The Stuff Chewable - they are designed specifically for passing drug tests.
