Maintenance at the back of the mind
QUALM already builds in future maintenance in the design phase and during the installation. For example, we close trenches that we have dug with clean sand to avoid damage. And we make sure that the inspection and maintenance points remain easily accessible, whether you ask QUALM to do the inspection and maintenance or someone else. It goes without saying that we can always do maintenance work on mains that were not laid by us. An alternative is to opt for our total package.
Flushing and lubrication
While carrying out inspections, QUALM does preventive maintenance straightaway. Our engineer lubricates connection points and valves and checks the check valve. You are required to flush your mains once or twice a year to prevent growth, dirt and blockage. And with our flow measurements we check if the required flow and pressure are available for fire protection.
