Frequently Asked Questions

A whole-home system (also called point-of-entry) is installed on your main water line, so every faucet, shower, and appliance in the house gets filtered water, not just one tap. Depending on the configuration, it can help reduce chlorine, sediment, and other common contaminants throughout your home.

Long Island relies on a sole-source underground aquifer, and homeowners across Nassau and Suffolk commonly deal with PFAS (including from the Bethpage plume), 1,4-dioxane in parts of Suffolk, chlorine and disinfection byproducts, and hard water. Private wells can also carry iron, manganese, and elevated nitrogen. The right system depends on what is actually in your water, which is why every recommendation starts with a free in-home test.

Whole-home filtration treats all the water entering your house and is ideal for chlorine, sediment, and hard water. Reverse osmosis is a point-of-use system, usually under the kitchen sink, that delivers highly purified drinking water. Alkaline and mineralizer systems add beneficial minerals and raise pH for better-tasting water. Many Long Island homes use a combination, and we recommend the mix that fits your water and household.

Cost depends on your home's size, whether you are on municipal or well water, and the specific contaminants we need to address, so there is no one-size-fits-all price. After your free in-home water test, a specialist recommends the right system and gives you transparent pricing with no obligation. Every installed system is backed by a 10-year guarantee.

Yes, it is completely free with no obligation. A local pHountain specialist comes to your home, tests your tap water, and explains the results in plain language. If your water warrants a system we will recommend one; if it tests clean, we will tell you that. Either way, the results are yours to keep.

Yes. Well water and municipal supply call for different treatment approaches, and our specialists are trained for both. Private wells, common across parts of Suffolk County, often need iron, manganese, sediment, and nitrogen addressed without any municipal treatment buffer. We match the system to your specific water chemistry.

Our systems are designed to be low-maintenance, and they are sized to protect your home's water pressure. Depending on the system, upkeep may be as simple as an occasional filter change, and replacement filters are available in our online store. We walk you through the exact service schedule for your setup during installation.

Yes, our certified technicians handle the full installation. A whole-home system connects to your main water line, while point-of-use systems like reverse osmosis are typically installed under the sink. Timing depends on the system and your home's plumbing, and your specialist gives you a clear estimate before any work begins.

Replacement filters and cartridges are available directly in our online store and shipped to your door. If you are not sure which filter your system needs, our team can point you to the right one, and your specialist will already have explained the replacement schedule during installation.

Reverse osmosis removes most dissolved solids, including beneficial minerals, which is why many homeowners pair it with a mineralizer or alkaline stage. That final stage adds minerals back and balances pH, so you get highly purified water that still tastes great.

These are two of the most talked-about contaminants on Long Island. PFAS can be reduced with technologies such as high-performance activated carbon and reverse osmosis, while 1,4-dioxane does not adsorb onto standard carbon and generally requires reverse osmosis or specialized media. The right approach depends on what is actually in your water, which is exactly what the free in-home test determines.

Every professionally installed pHountain system is backed by a 10-year guarantee. During your consultation, your specialist walks you through exactly what is covered for the system you choose, along with the recommended service schedule to keep it performing.

Many homeowners notice softer skin and hair after removing chlorine and other irritants from their shower and bath water. A whole-home system treats every tap, so the benefit is not limited to drinking water.

Filtered tap water is typically cleaner, far less expensive over time, and much kinder to the environment than single-use plastic bottles. With a home system you get great-tasting water on demand from every tap, without the ongoing cost and waste of bottled water.
