I have some issues with draining around my new home. I've noticed again there isn't a vent for the main line and instead air admittance valves on the kitchen sink and the washer drain. None in the bathroom I don't beilve. All the drains are slow and the washer was draining and the kitchen sink was gurgling untill I heard a huge bang and the washer blew the pipe right out and drained all over.. so I geuss my question is what can I do to try and help with this issue and what would a rough estimate be to add a main vent off the stack in a house with a basement 2 floors and an attic?(4 floors) Is this worth it to add in? What are some other issues that may cause this if any? Thanks in advance! Sorry if I come off Abit of a newb.. I kinda am.. [emoji18]
