Well first of all the vent pipe is clog with something, toilet don't flush the washer drain gurgles, shower does not drain right either, think because of the vent problem, how do I clear my vent out, The house was like this when I bought it, and they told me that the vent is probably clog with something, and I think I know why, because the vent does not have anything on it to to keep stuff out, do I need to get someone to clean that out or can I do this myself without making matters worse. Thanks in advance!
