I'm not sure if this is related to the same answer that you posted about drains gurgling. The sink in the kitchen & bath room and the tub are the reason I'm writing. The kitchen gurgles as water is being drained, I followed the drain line to the sewer line and the onlky thing I see is a possible level problem ( not enough drop )? The bathroom tub gurgles when it is being drained from a full tub, at the end of course. When you take a shower, the bathroom sink gurgles. Would a blocked vent cause this or do I need to pout in more vent pipes? All lines run to the sewer line that goes into an aeration system. We had a septic system and switched to the aeration system a number of years ago. Thanks for any help. Rick Smith
