Keep drains and sinks clear of hair - put it in the bin
Don't flush sanitary items, nappies or baby wipes down a drain
Use sink strainers in the kitchen
No fats, oils or food scraps ought to be washed down the drain

Be cautious of clip on toilet fresheners that can fall off and be flushed down the toilet
