sink chortling
#1
as the water on a kitchen sink drains there is a chortling sound, like the sink is gulping in air- there is no other problem with the sink draining. The sink drain pipe and air conditioner drain pipe go into the same pipe eventually. When you unplug the air conditioner pipe- the sink chortling stops. Could there be a clog in the air conditioner pipe? Help- this is driving us crazy!!!
