These guides cover the questions Auckland property owners, landlords and buyers actually ask about drainage: who is responsible for which pipe, what blocked drain work costs, how to read the symptoms, why tree roots get in, what a CCTV survey shows, who pays in a rental, and how to unblock a toilet, sink, shower or outside drain yourself.
