House makes burping noise

Noise started a few days ago. Based on what I've read on this site, I think it is a clogged vent. I'll run a hose to it tonight and see if that fixes it.

'Preciate having the forum here to try to figure some fo this stuff out. Will let you know if it works.

house makes burping noise - update

Ran water down both vents. It didn't back up. House still makes a noise.

Any suggestions on what to try next?

Can you be more clear as to the sound and where it's coming from?
