Your water is treated. It isn’t filtered.

Long Island drinks from the aquifer under our feet. The water company adds chlorine so it stays safe in the pipes. Safe to deliver isn’t the same as good to use. Here’s what still comes out of your tap.

Chlorine

Added by the water company to keep germs out of the pipes.

You notice
A pool smell or chemical taste from the tap.
The fix
Carbon soaks it up before it reaches any faucet or shower.

Hard minerals

Calcium and magnesium the water picks up underground. Fine to drink, rough on your home.

You notice
White crust on faucets and shower heads, spotty glasses, and soap that barely lathers.
The fix
Softening resin grabs the minerals before they reach your pipes.

Dissolved solids

Tiny traces of salts, minerals, and metals you can’t see.

You notice
Water that tastes flat or off, so you buy bottled or keep refilling a filter jug.
The fix
Reverse osmosis under the sink, the same kind of filtering many bottled water brands use.

A real Long Island example: Bethpage

Gorash spent almost $200,000 building his house. Within a year, hard water had marked up the new faucets. We put in a softener and whole-home filtration.

Still buying bottled water?

That’s about $624 a year, or $3,120 over five years.

Reverse osmosis under your sink makes about 50 gallons of clean water a day, and it comes with every system.

How it cleans your water.

Water comes in from the street and runs through carbon, then softening resin, then out to every tap. Your kitchen sink gets one more step: reverse osmosis.

  2. Softening resinHard minerals that cause scale

  4. Reverse osmosisUnder the sink, 5 to 8 stages

Clean drinking water

Single tank: carbon on top, softening resin below, gravel at the bottom.

On well water? We add a sediment filter for sand and grit.

Two systems. Sized to your home.

Both filter and soften every tap, and both come with reverse osmosis under the kitchen sink. Neither is better. It comes down to how many bathrooms you have.

Single tank system cut open: coconut shell carbon on top, orange softening resin in the middle, gravel at the bottom, next to its brine tank
1 to 2 bathrooms

Single tank + RO

Carbon and softening resin layered in one tank, plus reverse osmosis under the sink.

  • Coconut shell carbon takes out chlorine and chloramine
  • USA-made resin softens water to stop spots and scale
  • 5 to 8 stage reverse osmosis for drinking water

Dual tank + RO

A dedicated carbon tank and a dedicated resin tank, so homes with 3 or more bathrooms keep their water pressure. Plus reverse osmosis under the sink.

  • Same carbon and resin as the single tank

Well water add-ons

Well water skips the city’s chlorine but can bring in sand, gravel, and grit. We add a sediment filter to either system.

  • Sediment filter for sand and gravel
  • Works with the single or dual tank

“I lived in Queens all my life. When I moved to Bethpage, Long Island, I found out the water was not the best water here. I started getting dry skin and losing hair. Same thing with my wife… It’s a good investment.”

GorashBethpage, NYVideo review

“I don’t ever want to be using [the filter jug] again… I want water to be clean. Samad demonstrated how that would work for us and did the install. And we’re very happy with it.”

Is Long Island tap water safe to drink?

Public water has to meet safety standards, and chlorine is part of how it stays safe. A home system is about what’s left over: the chlorine taste and smell, and the minerals that build up on everything.

What’s the difference between hard and soft water?

Hard water carries calcium and magnesium from underground. Soft water has had those minerals taken out, so it won’t leave crust, spots, or scale.

I have a filter pitcher or a fridge filter. Isn’t that enough?

Those clean one glass at a time at one tap. A whole-home system covers every faucet, shower, and appliance, and reverse osmosis goes much further than a pitcher for drinking water.

Will soft water taste salty?

No. Softening swaps the hard minerals for a very small amount of sodium most people can’t taste, and your drinking water runs through reverse osmosis anyway.

How much does a system cost?

A single tank system with reverse osmosis starts at $3,250. Your exact price depends on your home, and you get it at the free estimate.

Single tank or dual tank, which is better?

Neither. They do the same job. Homes with 1 to 2 bathrooms get a single tank. Homes with 3 or more get a dual tank, with carbon and resin in separate tanks, so the water pressure holds up.

Is reverse osmosis included?

Yes. Both systems come with a reverse osmosis unit under the kitchen sink. It filters your drinking water in 5 to 8 stages, removes 94 to 99% of dissolved solids, and makes about 50 gallons of clean water a day.

I’m on well water. Can you help?

Yes. Well water doesn’t have city chlorine, but it can bring in sand, gravel, and sediment, so we add a sediment filter. We’ll go over it at your estimate.

What does a system need after it’s installed?

Add salt to the brine tank now and then, and change the reverse osmosis filters on schedule. The control valve uses ceramic discs for less upkeep and keeps its settings for 72 hours if the power goes out.

Where do you install?

All over Long Island, in Nassau and Suffolk counties.
