Below are some of the most common causes of commercial drainage and plumbing issues:

  • Fat, Oil & Grease Build-Up – A major issue in restaurants and food service businesses, where grease and fats restrict pipe capacity, leading to slow drainage and persistent blockages.

  • Tree Root Ingress – Roots infiltrating underground drainage pipes, causing cracks, collapses, and severe obstructions.

  • Wet Wipes & Non-Flushables – Items that don’t break down, leading to long-term drainage blockages and plumbing failures.

  • Foreign Objects – Sanitary products, cleaning wipes, and other materials accumulating in commercial drainage and plumbing systems, restricting water flow.

  • Food Waste & Organic Debris – Common in kitchens and hospitality settings, leading to clogged drains, pipe damage, and potential hygiene issues.

  • Collapsed or Damaged Pipes – Structural failures due to ground movement, wear and tear, or poor installation, requiring urgent repairs.

  • Soap Scum, Limescale & Corrosion – Frequent issues in commercial restrooms and industrial plumbing systems, leading to reduced water pressure and blockages.

  • Leaks & Burst Pipes – Hidden leaks and pipe failures causing water damage, pressure loss, and costly operational downtime.
