I have used a 25 foot snake lots of draino and am not getting any where the sink is still plugged. What else can we do. I refuse to pay a plumber hundreds of dollars for something I can fix besides I don't have money to pay at the moment Any ideas what else I can do. I have taken the pipes off and drained water and it keeps filling up.

We went under the sink and also through the trap in basement pipe - where is the roof vent is it in the attic or actually on top of the roof and what does it look like. Thanks

I never knew a roof vent existed - but question is where is it in attic? Or outside on roof?
And how is it connected to a sink? Thank you.

When you snaked the sink did you snake it from the trap or from the kitchen roof vent? Answer me and I'll answer you. Regards, Tom

A roof vent runs out the roof. On a two bath house, as a rule you have three vents. One each on a bathroom lavatory that vents the group, and a kitchen sink vent. If you have a laundry room that could be another vent. Sometimes we tie them all togather in the attic so that we only have one pipe coming out the roof. This is called reventing. It is possible that the bulder terminated the vents in the attic but I don't see how that would pass inspection. A vent that does not terminate through the roof is called a local vent. I am giving these terms so that when you talk to your plumber friend you will be on the same wave length. There is only one way to prevent sewer gas fron escaping from a local vent that terminates inside a wall. This is a mechanical vent that is spring loaded so that it lets air in to vent but stops sewer gas from getting out. This vent is called a Studor Vent. A plumbing drainage system has traps on each fixture. These traps keep sewer gas from escaping into your house. On a unvented system the water draining sets up a suction that syphons the water out of the trap letting sewer gas out into your house. I have tried to explain how vents work and the different kinds. You asked how important venting is. Vents are necessary for a plumbing system to function\,(see image).
And now you know more about vents then you ever wanted to. Regads, Tom
