Vent Pipe Video

VIDEO SUMMARY

Ever notice that little round pipe on your roof? What's it connected to? Inside the house, this vent pipe is connected to the plumbing system. The vent pipe is connected to the sink drains. This pipe provides make-up air when you drain a sink or bathtub. Since the drain pipes are full of air before you pull the plug, this air has to be replaced as the water pushes the existing air down the drain.

If you notice a gurgle when flushing the toilet, it might be an indication that the vent pipe is clogged. Get up on the roof and put a garden hose down the pipe and turn on the water. Be sure to have someone inside checking for any leaks. The water from the hose hopefully will flush out the blockage and your gurgle will disappear.

I am struggling with a leak that I have now removed drywall from the ceiling in my kitchen to only find that there is no "leak". With cold temps outside, my vent pipe is forming condensation and that is what is dripping down and onto the drywall causing it to crack. I crawled into the attic and there is insulation around the pipe on the attic floor, just like the entire attic. Any ideas on this one? I am stumped.

My kitchen smells like spoiled garbage. I live in Royal Oak Michigan and it is winter here now. What can I do to get rid of the stink? Seems to be coming from my kitchen sink and the cupboards directly near the sink. I tried using bleech and it worked for 1/2 a day, but then the stink came back. What is it? How can I fix it? Is my stink pipe perhaps clogged? If so, how can I check to find out? It sooo STINKS HELP Lillian
