  • What is the difference between commercial and residential plumbing?

    Commercial plumbing systems are generally larger and more complex than residential ones, often spanning multiple floors and handling heavier usage. They require specialised equipment, high-capacity pipes, and strict compliance with building codes. Regular maintenance is essential to ensure reliability, as even minor issues can disrupt daily operations and result in costly downtime.

  • What are common commercial plumbing problems?

    Frequent issues in commercial plumbing include blocked drains, leaking pipes, faulty water heaters, and sewer line problems. Because businesses experience higher water usage, these problems often occur more frequently and at a larger scale than in homes. Prompt repairs, regular inspections, and preventative maintenance can reduce the risk of serious disruptions or expensive emergency repairs.

  • How often should a commercial plumbing system be inspected?

    Most experts recommend that commercial plumbing systems be inspected at least once a year, although high-use facilities may require more frequent checks. Inspections typically cover leak detection, pipe condition, water heaters, and backflow prevention devices. Routine inspections help identify issues early, reducing the chance of unexpected breakdowns that could affect business operations.
