I just bought a older home, the plumbing is all brand new, there is a vent running off the kitchen sink but it doesn't drain properly, it'll drain fast then stop. After a few minutes you'll hear what sounds to be like air finding it's way up the pipe. Then when I pull the plug out it drains fast and stops again. I think it's a venting problem but I am not a expert?
