15L - AUTO15M - Auto Digital Metered Water Softener with Autotrol 255/760 3/4" Valve

This is a complete 15-litre domestic water softener from WrekinWater's Kennet range, built around an Autotrol 255/760 digital metered control valve with 3/4" connections. Rather than regenerating on a fixed daily timer, it tracks your actual water use and only regenerates when the resin bed is genuinely due for a recharge, which means less salt and water used over time. It's sized for smaller households and properties where a compact, efficient softener is the priority.

Signs you need a new system

• Limescale is building up on kettles, taps and shower screens and you've never had a softener fitted.
• Your current softener needs increasingly frequent repairs or replacement parts are getting hard to find.
• Your existing unit is old and its regeneration settings no longer match how much water your household actually uses.
• You're moving into a property with no softener installed and want reliable soft water from day one.

Inside the resin tank, hardness minerals in your water swap places with sodium ions held on the resin — a process called ion exchange — and periodically the resin needs a brine regeneration to reload it with sodium and flush the collected hardness away. Because this valve is metered rather than timer-based, it only runs that regeneration when your actual water use says it's needed, instead of on a fixed schedule that either wastes salt and water on days you barely used any, or falls short on days you used more than usual.

WrekinWater is a family-run business based in Bettisfield, Shropshire (UK Company No. 11000488), that has served more than 50,000 customers over 15 years and stocks major control valve brands including Pentair Fleck, Autotrol, Clack and Kinetico — so parts and support for this Autotrol-based system stay available long after you've bought it. The business is rated "Excellent" on Trustpilot.

Installation

1. Confirm your incoming water hardness and rough daily water use before ordering, so the softener is sized correctly for your household.
2. Arrange for a qualified plumber or water treatment engineer to check your pipework, drainage and any overflow provision beforehand.
3. The installer connects the softener to the mains supply, drain and overflow, then wires in the digital control head.
4. The engineer programmes the metered regeneration settings to match your incoming hardness and typical water use.
5. Run an initial regeneration cycle to confirm the valve, brine tank and drain connection are all working correctly.
6. Book a follow-up check a few months in to confirm the settings are still matched to how the household is using water.
