In the water softening supply industry, we often see customers debating between fixing an old unit or buying new. Generally, if the issue is a stuck piston or a faulty circuit board in the control valve, a repair is simple and cost-effective. However, if the main pressure vessel has cracked or if the resin has become “mushed” due to chlorine exposure—typically happening after 10-15 years—the entire unit needs replacement.

Another critical factor is salt efficiency. Older “time-clock” softeners that regenerate every few days regardless of usage are incredibly wasteful. If you are supplying salt to an old unit constantly, upgrading to a modern “demand-initiated” system, which only regenerates when necessary, will pay for itself in salt and water savings within a few years.

To keep your softening equipment running at peak performance, salt management is key. We recommend using high-purity salt pellets to prevent the buildup of “salt sludge” at the bottom of the brine tank. Homeowners should also watch for “salt bridging,” where a hard crust forms over the water level; a quick poke with a broomstick breaks this up and ensures proper regeneration.

From a supplier’s perspective, the longevity of the resin bed is paramount. We suggest using a resin cleaner liquid once every 6 months to strip away iron and organic fouling that regular salt regeneration cannot remove. This simple maintenance step keeps the resin beads clean, porous, and effective for their full expected lifespan.
