We have air trapped in our plumbing, is there a way to get it out?

We live in an older home with an outdated plumbing system (probably not vented). Lately, every time we flush the upstairs toilet it makes a loud clanging noise like there is air trapped in the system. Is there a way to get it out so it won't make such a terrible racket? We have one bath on the second floor (this the one making the noise), one on the first floor, and just a utility sink in the basement. Thanks for your input!

  • On the roof of your home you should see pipes coming out usually right above the bathrooms and kitchen sinks. Those could be plugged from debris or birds or even critters. Is the toilet flushing? is it the running water clanging? or the pipes not draining?
