What are the main causes of blocked drains?

Today’s post is a simple one.

Amazingly, 83% of all blocked drains in Australia are caused by tree roots!

Cooking fats, oils and grease, human and pet hair, sanitary products, facial tissues and napkins used instead of toilet paper, dental floss and broken or collapsed pipes make up the other 17% of blocked drains.

If you have persistent problems with your sewer pipes caused by tree roots then this simple instruction found in the “head” or toilet of an ocean racing yacht, makes a lot of sense to me. I’m sure the yacht owners won’t mind if you put a similar sign in your troubled bathroom.
