How to Maintain a Water Softener

Maintaining a water softener is refreshingly simple: keep it topped up with the right salt, clear the odd salt bridge, and give the brine tank a clean once a year. Do that and your softener will keep limescale at bay, protect your pipes and appliances, and deliver soft water for years with very little effort from you. Here is everything you need to keep yours running smoothly.

The single most important job is making sure your softener never runs out of salt. Most units work best when the tank is kept between a third and half full, so it is worth a quick monthly glance rather than waiting until it is empty. Always use a salt made specifically for softeners, and stick to the type your machine is designed for. You can stock up any time from our water softener salt range.

A salt bridge is a hard crust that forms across the tank, leaving an empty gap underneath. When this happens the salt above cannot reach the water below, so the softener stops regenerating even though the tank looks full. If your water suddenly feels hard again but there is still plenty of salt in the tank, a salt bridge is usually the culprit. Gently break it up with the handle of a broom or a long tool, taking care not to damage the tank.

Over time, a little sludge or fine salt residue can gather at the bottom of the brine tank. Cleaning it out once a year keeps everything working efficiently. Let the salt run low, unplug the unit if required, remove any remaining salt and residue, wash the tank with warm soapy water, rinse well, then refill with fresh salt. Always check your manufacturer's instructions first, as steps vary between models.

Every so often it is worth confirming your softener is set correctly for your local water hardness. If limescale starts creeping back or your water feels different, the hardness setting may need adjusting. Getting this right means you use the perfect amount of salt: enough for soft water, without wasting any.

Keep an eye out for a few tell tale signs that something needs looking at:

• Limescale returning on taps, kettles or shower screens.
• Water feeling hard again, or soap not lathering as well.
• The softener not using any salt, so the level never seems to drop.
• Salt sitting untouched for weeks, which can point to a salt bridge.

Catch these early and the fix is usually quick, whether it is a top up, breaking a salt bridge, or a simple clean.

A well maintained water softener quietly does its job in the background, protecting your home from limescale year after year. The easiest way to stay on top of it is to never let the salt run low. Browse our water softener salt and keep a spare bag ready, so a top up is always to hand.
