Sevenoaks FAQs
Why is the water pressure getting worse in my commercial building?
Reduced water flow or pressure can sometimes be caused by scale, sediment or other deposits building up within pipework and equipment. An investigation can help identify whether cleaning, flushing or descaling is required to restore system performance.
Why do radiators and heating systems keep developing cold spots?
Cold spots can be a sign of poor circulation caused by sludge, corrosion products or debris within a closed heating system. Water testing can help determine the condition of the system before flushing or chemical treatment is recommended.
How do I know if the water in my building is safe and clean?
Changes in water colour, smell or clarity can indicate a potential water quality issue, although not every problem is visible. Professional water sampling and analysis can help identify contamination and determine whether further cleaning, disinfection or treatment is required.
What causes corrosion inside commercial heating and chilled water systems?
Corrosion can develop when water chemistry within a closed system isn't properly controlled. Over time, this can create sludge, damage components and reduce system efficiency. Regular water testing and appropriate chemical treatment can help control corrosion and protect the system.
Why does my commercial water tank have sediment at the bottom?
Sediment can accumulate in cold water storage tanks over time and may affect water hygiene and quality. If debris, staining or contamination is found during an inspection, professional tank cleaning and disinfection may be required.
What happens if a new heating system isn't properly flushed?
Installation debris, oils, flux residues and other contaminants can remain inside new pipework. If these aren't removed before commissioning, they can contribute to blockages, corrosion and poor system performance. Pre commission cleaning helps prepare new systems for operation.
Can limescale damage commercial water systems and equipment?
Yes. Heavy limescale deposits can restrict water flow, reduce heat transfer and affect the efficiency of water system components. Where significant deposits have developed, professional descaling may be required to remove the scale.
Who can diagnose problems with a commercial water system in Sevenoaks?
Clear Flow Water provides commercial water treatment services throughout Sevenoaks and the surrounding areas. We can investigate issues including poor water quality, corrosion, sludge, scale and contamination before recommending the appropriate cleaning, testing or treatment.
