Kitchen Sink Trouble w/ Air Vent??
Posted by Raven on May 01, 2002 at 18:40:58:
My kitchen sink drains extremely slow. We have eliminated all possible problems save one. The sink is on an island and the air vent is under the sink. I think it not high enough to work as it should. It's actually below the level of the water in the sink. Can a vent line be run out from the pipes under the house and up or does it have to come off the pipes above the U shaped piece just below the actual sink drain holes? I'll take any help I can get on this one.. Thanks
