I am a big fan of trying to fix things on my own but sometimes you have to give in to the fact that you are in over your head and hire a professional to do things right. I know nothing about spring plungers so why would I play around with them? I wouldn't. On the same token if I know nothing about plumbing or fixing a dryer then I shouldn't be messing around with them either. There are lots of instructions on how to do things on the internet but you have to ask yoruself if you are in over your head. Don't mess with things you know nothing about, it will end up costing you more in the long run.
