Blocked drains caused by the flushing of toilet paper alone, really? Sounds absolutely absurd, and yet, for many years now, this problem has been on the increase. Some sanitary products may need to be built to last, but not toilet paper! Toilet papers, constructed similarly to kitchen roll, will not break down when flushed and will inevitably lead to blocked drains. So, repeat blockages? Toilet paper possibly the culprit? For free advice, call Core Drainage.
