Commercial Site Inspections

Our Operations Manager will attend your commercial or industrial premises and conduct a thorough site inspection, auditing all plumbing fixtures and compiling a plumbing asset register. The inspection will be transferred into a comprehensive preventative plumbing maintenance plan, with workflows created on our job management software simPRO.

The inspection, and following site visits, will inevitably focus on the following main preventative maintenance areas:

Water Leaks

  • Our plumbers will check for mould and mildew
  • Thermal imaging cameras will be utilised for in wall leak detection of the commercial premises to check for moisture
  • Puddles and water spots will be photographed and be included in the immediate rectification recommendations on the report

Water Pressure

  • Your commercial property’s water pressure will vary based on the site and water usage. Sanitary plumbing fixtures on site will have a pressure range between 300-600kpa through to fire services requiring working pressure of 1700kpa. McCarthy Plumbing Group can advise you of the different plumbing services you have installed on your site and the regulations attached to each service to ensure compliance at all times

Hot Water Systems

  • Our plumbers will check your hot water system’s productivity levels by checking its age, if they have leaks, water temperature outputs, overflows, safety valves, frost protection valves. Any safety concerns will be itemised and prioritised.

Backflow Prevention Testing

  • Backflow can be extremely dangerous, and if it occurs Sewage can travel through to your drinking water supply through backflow, or back-siphonage, causing infections and diarrhoea. Larger buildings and commercial premises are required to have backflow prevention devices which require annual testing to ensure effective operations


  • The plumbers at McCarthy Plumbing Group will check for rust and limescale around all fixtures and fittings such as taps, showers and eye wash stations
  • They will also check for signs of rust and corrosion of pipes to ensure the quality of drinking water isn’t affected.

Valve Efficiency

  • An audit of all safety & shut off valves will be inspected to ensure they are working efficiently, and all defective valves will be recommended to be replaced immediately. As a part of our audits we ensure a site valve schedule is established ensuring in the event of a burst or accident the correct valves are isolated.


  • Our plumbers are all trained in effective drain clearing and jetter operations and during the commercial plumbing maintenance inspection will test drain line flow rates and complete CCTV camera inspections of all drains.
  • Blocked drains can cause major plumbing problems in future and need to be rectified in a timely manner

Roof plumbing            

  • Our roof plumbers will conduct a thorough roof and gutter inspection, including roof condition report, downpipe inspection and environmental examination to prevent future roofing problems.

Other plumbing

  • No commercial or industrial premise is the same; we work with clients who have extensive gas fitting needs, chemical drainage requirements, fire services and laboratories. We can tailor our technician/s to the needs of our commercial plumbing client.
