There are single-sample tests and split-sample tests. If you've got a split-sample test, the second half of the sample goes into the freezer for six months regardless. For single-sample and the other part of a split-sample test, they retain the sample if it tests positive, but if it tests negative they normally dump it.

If you drink 1 gallon of water and then have a urine test in the nest 48 hours will you pass?
This is not a guaranteed method . Drinking water will dilute your sample possible allowing it to dive below the level you need to get to pass the test. It will also cause your urine to become very clear and labs will be able to tell that you have been trying to flush your system. Labs check for gravity, pH, creatin levels, etc (home test can not) so if you diluted your urine you can pass a home test , but not a Lab (will show dilution which is just like failing the test).
