Frequently Asked Questions

What Products Fall Under Water Treatment?
Water treatment covers the products used to test, clean, protect, and improve the quality of water in heating and plumbing systems. Our range includes:
  • Water Test Kits – check system water quality and inhibitor levels
  • Power Flush – equipment for clearing sludge and debris from systems
  • Filters – magnetic and inline filters to capture contaminants
  • Chemicals – inhibitors, cleaners, and other treatment fluids
  • Water Treatment Packs – grouped products for common tasks
  • Scale Reducers – help limit limescale build-up
  • Water Softeners – reduce hardness across the water supply
What Is the Difference Between a Power Flush and a System Filter?
A power flush is a process used to clear existing sludge and debris from a heating system, typically carried out during servicing or when installing a new boiler. A system filter, by contrast, is fitted in-line and works continuously, capturing contaminants as water circulates. Many installers use both: a flush to clean the system, then a filter to help keep it clean.
When Should I Use a Scale Reducer or a Water Softener?
Both help manage the effects of hard water, but they work differently. Scale reducers are designed to limit limescale build-up, often protecting a specific appliance or point in the system. Water softeners treat the wider supply, reducing hardness across the property. The right choice depends on the water conditions in the area and what the customer wants to protect
How Do I Choose the Right Water Treatment Products for a Job?
Start with the condition of the system and the local water. It helps to weigh up a few factors:
  • System condition – an older or dirty system may need a flush before treatment
  • Water hardness – harder water areas may call for scale reduction or softening
  • Protection level – add a filter and inhibitor to help keep systems clean
  • Task type – testing, cleaning, and ongoing protection each need different products
