Blocked drains can be a real hassle, tree roots can make their way into the drain which will cause a blockage.
Fats and oil blockages are very common and can be avoided by not pouring oil down the sink. Drain the excess oil out into a suitable container and wipe down with paper towel before washing. This will limit the ammount of fats, oils and food scraps that will enter the drain.
Other blockages we come accross are due to sanitary products being flushed down the toilets. These items are not designed to break down and will cause a blockage.
