Benefits of Water Treatment

Our plumbing company offers both whole-house and point-of-use (POU) water treatment solutions. A water filter will provide healthier drinking water and better water quality for cooking, showers, and laundry. It will foster a healthier living environment and help you save money over the life of the system.

These signs may indicate that your home could benefit from water filtration:
  • Unpleasant odors or tastes
  • Cloudiness or discoloration
  • Visible sediment in the water
  • Dry-feeling skin or hair
  • Frequent reliance on bottled water

Whole-Home Water Filtration Systems

A whole-house or point-of-entry (POE) water filtration system functions between the main water line and the home’s plumbing system. That way, the system can filter all water before it enters your home. Professional sizing is crucial in such a scenario since an undersized water filter will be a bottleneck. Most water purifiers have a prefilter, a primary sediment filter, and activated carbon for the adsorption of chemicals and gases. Other options include an ultraviolet light for pathogen control and various post-filtration conditioners.

Hard Water Treatment Options

A reverse osmosis system is a POU solution that can both filter and soften your drinking water. A water softener is a POE system that can protect your pipes, fixtures, and appliances. You can install a water softener in combination with a POE or POU water filter.

Hard water treatment can provide many potential benefits.
  • Reduced mineral residue on skin and hair
  • Less scale buildup on fixtures
  • Improved soap and detergent performance
  • Reduced mineral buildup in water-using appliances

Signs You Need Hard Water Treatment

Many homes in Nassau County have hard water. You can determine your water hardness through a professional test performed by us. Households with hard water often experience issues due to that hardness. These can include reduced appliance efficiency, scale buildup on fixtures, high detergent usage, dull laundry, spotty glassware, and so forth.

Frequently Asked Questions

Here are answers to some common questions about water filtration and softening. Contact us at your convenience with any additional questions about our services.


A water filtration system may reduce sediment, unpleasant tastes, odors, and specific contaminants, depending on the equipment and filtration media. Whole-home systems treat water before it reaches household fixtures, while point-of-use systems focus on drinking and cooking water. Filtration may also reduce reliance on bottled water.

You may notice the symptoms of hard water, such as scale buildup on your fixtures and shower walls. Other signs you may have hard water include quickly clogging aerators, dull laundry, spotty glassware and dishware, and high detergent usage. The best way to know for certain is to schedule us for a water quality assessment. We can determine precisely how hard your water is and, if necessary, explore your hard water treatment options.

We offer a range of water purification and softening solutions. Which one is right for your home depends on your unique water quality challenges, goals, and budget. Our experts recommend an in-home consultation, including a water quality assessment. We can then answer your questions and explore your water purification options.
