A blocked drain can be a nightmare. It will inevitably happen to any home plumbing system and your kitchen sink is highly susceptible. The blockage that won’t go away on its own will require immediate attention to allow the water to drain away. The easiest solution is to call North Wahroonga Plumbing to help unblock the kitchen sink and perhaps check all the other drains while we’re there.
Rather than try to do it yourself with a plunger or hazardous chemicals, call Tom at North Wahroonga Plumbing to get immediate help.
