The TwinSoft F73 keeps one valve in active service while the other stands by — ready to take over the moment the first reaches capacity. When regeneration is needed, the system switches seamlessly, so your household always has soft water, even during regeneration cycles.

The patented RoyalSoft ceramic discs are diamond-hard — they won't wear out like traditional seals, spacers, and pistons. Corrosion and abrasion resistant, they ensure many years of worry-free operation with virtually no maintenance. Backed by a Lifetime Guarantee on wear parts.

Up-flow regeneration efficiently washes the media bed from the bottom up, exchanging more grains per pound of salt than conventional down-flow systems — reducing salt consumption and water waste with every regeneration cycle.

The F73 valve offers 7 advanced programming options with fully adjustable cycles, and program functions remain in long-term memory. A 72-hour backup protects your settings against power outages — so your softening schedule is never disrupted.

How does a dual-tank system work?

The TwinSoft keeps two tanks in the system simultaneously — one in active service and one on standby. When the active tank reaches its softening capacity and needs to regenerate, the standby tank automatically takes over. This means your home always has access to soft water, even during the regeneration process.

Who is the TwinSoft best suited for?

The TwinSoft is ideal for larger households with high daily water usage, families that can't afford any interruption in soft water, and light commercial applications. If you've ever noticed your water going hard during regeneration cycles, the TwinSoft solves that problem entirely.

How do I test my water hardness?

Fill out this form here and a certified water technician will schedule an in-home test for you. Or bring a sample into Clean Water Pro and a tech will test it for you in-store.

What are the real benefits of a water softener?

Softened water reduces scale buildup in pipes and appliances, extending the life of your water heater, dishwasher, and washing machine. Most households also see up to a 50% reduction in soap and detergent use, lower energy bills, and fewer appliance repairs over time.

Is softened water safe to drink?

Yes, softened water is safe for most people. Salt-based systems add a small amount of sodium to the water. If you're on a low-sodium diet, a reverse osmosis drinking system can be installed alongside your softener to provide purified water at the tap.

What maintenance is required?

Salt-based systems need periodic salt refills — roughly once a month for most households. The TwinSoft's patented ceramic discs eliminate the need to replace traditional wear parts, making the system virtually maintenance-free beyond routine salt top-ups.
