Team Fortress 2 - How to Deal with Sentries as Pyro Pt. 1

Here's one of the ways to deal with level 3 sentry guns in Team Fortress 2 as a pyro. This requires enough room to be able to run in and back out of range to trigger the rockets. Simply walk into range using the standard Pyro flamethrower (the Backburner does not have the propane burst ability). When you hear the rockets launch, step back out of range of the sensor so you don't get Swiss-cheesed. When the rockets near, hit the right-click to activate the propane burst before you get hit, and it will send the rockets back in the very angle you're facing with the flamethrower. Time it well and aim, it should take 3-4 rockets to destroy the sentry. You will need to get health or have a medic help you.
