I have moved into an apartment where the kitchen sink was put in as an afterthought and as such was not vented in any way. Is there a way to simply tee off from the drain and run a short stretch of PVC under the basin of the sink and up to above the level of the drain in order to vent the drain?
I have seen reference to what someone calls a cheater vent, any idea what that is and how to make one?
Thank you in advance for any help I receive. :o
