Costs, Schedules & Warranty Care
Our Culligan Harvey twin-tank water softeners operate on nothing but your mains water pressure, so there’s no electricity bill spike to worry about and no annual service to book in. Culligan Harvey water softener maintenance really is that simple.
Keep the block salt topped up and we’ll take care of the rest. Once every 2 to 3 years, a certified engineer can give the system a quick health check to keep everything performing well and help protect your 10-year manufacturer guarantee. Visits are priced up front on a fixed rate, and our Care Plans bundle in salt delivery and filter changes, so there’s never a surprise on the bill.
The true cost of ownership: Why non-electric systems save you money
Going non-electric on your water softener is a smart long-term investment:
- Your softener works on mains water pressure rather than a motor, so there’s no power bill for it across a working life of 15 to 20-plus years, and that saving starts from day one.
- Single-tank electric models rely on digital timers and circuit boards to drive their regeneration cycles, which is usually where the expensive out-of-warranty repairs come from. Our twin-tank softeners don’t rely on those electronic parts, which removes those potential failure points.
- Dual-cylinder technology cleans the resin bed with already softened water, and only when the resin actually needs it, not on a fixed timer. Most single-tank systems regenerate on a schedule regardless of how much water you’ve used, wasting salt even when the house is empty. That precision can cut your ongoing costs by up to 30% against a comparable single-tank system.
Routine home maintenance checklist (What you need to do)
There’s really very little for you to do to maintain your Culligan Harvey water softener beyond:
- Checking the salt hopper now and then and dropping in a fresh block of salt as soon as it’s getting low. You won’t need to move the unit. The salt compartment sits right at the front, nice and easy to reach.
- Keeping the main water supply open. Your softener will carry on producing softened water at a steady rate all year round.
- Forgetting the wiring altogether. There’s nothing to switch off before you go away, since none of it needs electricity in the first place.
Professional engineer servicing: How often and what’s included?
So, how often should a water softener be serviced? A certified engineer check every 24 to 36 months helps keep performance optimal and protect your 10-year manufacturer guarantee.
Each visit includes a full 12-point inspection, covering:
- Mains water pressure and softened water hardness testing
- Sanitisation of the internal brine valves, mesh filters, and seals
- Metering valve calibration so your softener uses salt and water at the right rate
| Support option | What’s included | Value and protection |
|---|---|---|
| Fixed-rate health check | A full 12-point engineering inspection, resin sanitisation, seal replacements and flow tests. | No hidden fees: your call-out price is fixed and confirmed before we arrive, with no hourly add-ons. |
| Harvey ArcCare™ plan | Scheduled engineer visits, automated block salt deliveries, filter replacements, and full parts and labour cover. | Predictable monthly payments that spread the cost and extend the life of your softener. |
| Spare parts and DIY accessories | Direct factory access to genuine seals, bypass valves, taps, and filter cartridges. | Keeps your softener fully operational well beyond 15 to 20 years. |
Protecting your 10-year guarantee and household plumbing
Periodic health checks help protect two things beyond the softener itself. The first is your home’s plumbing. Consistently soft water stops limescale building up inside your boiler, power showers, and washing machine, protecting appliances that hard water gradually damages from the inside out. Left unchecked, that build-up can cost the average household up to £400 a year in unnecessary energy and repair bills, and it cuts years off the working life of everything it touches.
The second is your guarantee. Your Culligan Harvey water softener comes with a 10-year manufacturer guarantee. A simple health check every few years helps protect the full value of that cover without turning ownership into an annual servicing commitment.

Quick diagnostics and DIY troubleshooting
You can safely check for some water softener issues yourself before booking an engineer:
- Salt level not dropping? Have a look inside the dry chamber for a hard crust known as a salt bridge. It forms when humidity hardens the surface layer, leaving a gap underneath where the water can’t reach the salt. Break it up gently and you should see it flowing normally again.
- Water suddenly feels hard? Check that there’s block salt in the hopper, then make sure the red bypass valve is fully closed. Left even slightly open, it lets hard mains water slip past the softener altogether.
- Water constantly flowing to drain? Close the bypass valve to isolate your softener, then give our team a call for step-by-step guidance.
Hassle-free, low-maintenance water softening
We built our Culligan Harvey softeners to ask very little of you and give a lot back. In practice, that’s a top-up of block salt every so often in return for soft water flowing from all your taps and appliances, all backed up by a 10-year manufacturer guarantee.
