Crown Water Softeners produced by Harvey's Water Softeners are British made high end water softeners. Made to the highest specification and performance they offer the lowest running cost of most Non-Electric Softener. Without the need for routine servicing, it makes the total cost of ownership very attractive compared to Single Tank Electric Softeners.

This softener uses fine resin beads to speed up the regeneration cycle, its dual cylinder design cuts wastage and maintenance costs. Beads in one cylinder can self-regenerate using soft water from the other, keeping valves free of lime scale damage, while the online cylinder keeps up the continuous household supply.

Superior Salt Loading
This unit uses a purpose-designed block salt which comes in an easily handled size that's more convenient to load and store. When the block needs replacing, the unit's special sliding lid gives extra easy access.

The Silent Performer
So economical - but so effective Although this water softener is very compact, its clever side-valve design allows for maximum softening capacity. So for a system that takes up little space, works unobtrusively, needs no mains electricity supply and virtually looks after itself - it's quite a performer.

Advanced Automatic Metering
It doesn't matter how much your water consumption varies, your Softener unit won't need adjusting - even if you go on holiday. That's because the water flow is accurately measured automatically, so only the right amount of salt is used at any time.
