Oahu’s Trusted Experts for Clean, Safe, and Great-Tasting Water
Clean, safe, and great-tasting water is essential for every home and business. Over time, Oahu’s water can contain minerals, chlorine, or impurities that affect taste, stain fixtures, and even reduce the lifespan of your plumbing system. At Waialae Plumbing, we specialize in water treatment and conditioning repair, replacement, and maintenance services to ensure your water is fresh, pure, and safe for everyday use.
Proudly serving the island of Oahu since 1994, our expert technicians work with a wide range of water filtration and conditioning systems — including filtration units, water softeners, and reverse osmosis (RO) systems — for both residential and commercial clients.
Why Choose Professional Water Treatment Services?
Even though Oahu’s water supply is generally reliable, local conditions and old plumbing systems can lead to:
- 1. Hard water that leaves stains or scale buildup on fixtures and appliances
- 2. Chlorine taste or odor in drinking water
- 3. Sediment or mineral deposits in pipes and water heaters
- 4. Reduced efficiency of plumbing fixtures and equipment
Waialae Plumbing can test your water quality and recommend the best solution to improve taste, clarity, and safety — all while helping you protect your plumbing system and appliances.
Our Water Treatment & Conditioning Services
Water Filtration SystemsIf your water has a cloudy appearance, metallic taste, or odor, it’s time to consider a filtration system. We install, repair, and replace whole-house and point-of-use filtration systems that remove sediment, chlorine, and other impurities from your water supply. Our experts can help you choose the right system to match your property’s water quality and usage needs.
Water Softener Systems Hard water is one of the most common issues across Oahu. It can cause mineral buildup in pipes, leave spots on dishes, and make soap less effective. Our team can install, repair, or replace water softeners that remove calcium and magnesium from your water, preventing scale buildup and extending the lifespan of your plumbing fixtures, water heater, and appliances.
Reverse Osmosis (RO) Filtration Systems For the purest drinking water possible, reverse osmosis filtration is one of the most effective solutions available. RO systems remove up to 99% of contaminants including chlorine, lead, fluoride, and dissolved solids. Waialae Plumbing provides complete RO system services — from installation to filter replacement and troubleshooting — ensuring clean, great-tasting water for your family or business.
