RainKing Purification Systems, a Florida-based water treatment company serving Central Florida homeowners since 2018, announced the launch of its new saltless water system as the company surpasses 5,000 customers served across the region. The newly introduced system is designed to address mineral scale buildup that damages plumbing, fixtures, and tankless water heaters without adding sodium to the water or requiring salt and brine discharge.

Why it matters

Many Florida homeowners struggle with hard water and mineral scale issues, which can lead to costly plumbing repairs and appliance damage over time. RainKing's saltless solution provides a low-maintenance way for families to protect their home's water infrastructure while keeping their water chemistry intact.

The details

RainKing's saltless water system conditions hardness minerals so they are less likely to adhere to surfaces, helping homeowners reduce scale without the ongoing maintenance of traditional salt-based softeners. The system operates without electricity, regeneration cycles, or wastewater discharge, making it especially attractive for homes with tankless water heaters and properties on septic systems. By reducing scale formation, the system supports more consistent appliance performance and can help extend the lifespan of plumbing components.

  • RainKing Systems was founded in 2018.
  • The company announced the launch of its new saltless water system on February 12, 2026.
