Question 1

What is a Whole Home Point of Entry Reverse Osmosis Water Filtration System?

Accepted Answer

A Whole Home Point of Entry Reverse Osmosis Water Filtration System is installed where the main water supply line enters your home or building, treating all water used on the premises — every shower, faucet, toilet, and appliance — rather than just a single tap.

Question 2

Where are LWS systems designed and built?

Accepted Answer

All Living Water Systems products are designed and built in the United States.

Question 3

What is the difference between the SS and LC models?

Accepted Answer

The only difference now is that the SS models have a premium Stainless-Steel Exterior along with stainless steel membrane housings and sound deadening design.

Question 4

What are the four stages of filtration?

Accepted Answer

Our systems use four stages: (1) Sediment Filtration — captures sand, dirt, rust, and large particulates. (2) Carbon Filtration — removes chlorine, chloramines, and VOCs. (3) RO Membrane — filters down to 0.0001 microns, removing up to 99.35% of lead, heavy metals, and dissolved solids. (4) Calcite Filter — re-mineralizes and stabilizes the pH of treated water.

Question 5

What is Reverse Osmosis (RO)?

Accepted Answer

Reverse osmosis is a filtration process that uses a semi-permeable membrane to remove ions, molecules, and larger particles from water. It is one of the most effective technologies for producing ultra-pure water.

Question 6

What is TDS and why does it matter?

Accepted Answer

TDS stands for Total Dissolved Solids — the total concentration of dissolved substances in water, measured in parts per million (ppm). Lower TDS generally indicates purer water with fewer contaminants.

Question 7

What is a Calcite filter and why is it included?

Accepted Answer

Calcite is a naturally occurring calcium carbonate mineral used in post-filtration to raise the pH of RO-treated water and reduce its corrosive potential. Without it, ultra-pure RO water can be slightly acidic and aggressive to plumbing.

Question 8

How much water can the systems produce per day?

Accepted Answer

Our LWS-5500 systems are rated at up to 5,500 gallons per day (GPD) under standard testing conditions, making them suitable for both residential and commercial applications. Our LWS-3500 are rated to 3,500 gallons per day using the same testing procedures.

Question 9

Does the system remove PFAS ('forever chemicals')?

Accepted Answer

Yes. PFAS (Per- and Polyfluoroalkyl Substances) are man-made chemicals that do not break down in the environment or the human body. They are found in many public water supplies and are effectively removed by our reverse osmosis filtration systems.

Question 10

Does the system remove microplastics?

Accepted Answer

Yes. Microplastics are tiny plastic particles less than 5mm in size. Studies have detected them in tap water worldwide. Our point-of-entry RO systems provide a highly effective barrier against microplastics.

Question 11

What other contaminants are removed?

Accepted Answer

Our systems are designed to remove a broad spectrum of contaminants including lead, heavy metals, bacteria, dissolved solids, chlorine, chloramines, VOCs, nitrates, and more.

Question 12

Will treated water protect my appliances?

Accepted Answer

Yes. Hard water, sediment, and dissolved minerals shorten the lifespan of water heaters, dishwashers, washing machines, and plumbing fixtures. By treating water at the entry point, you protect your entire home — reducing scale buildup, maintenance costs, and premature appliance failure.

Question 13

Is a Whole Home Point of Entry Reverse Osmosis Water Filtration System worth the investment?

Accepted Answer

The upfront investment in a Whole Home Point of Entry Reverse Osmosis Water Filtration System pays dividends over time. Reduced bottled water costs, fewer appliance repairs, lower energy bills from scale-free water heaters, and extended plumbing life all contribute to meaningful long-term savings.

Question 14

Do I still need a water softener?

Accepted Answer

In all cases, a water softener installed before the LWS Water Appliance can be beneficial to overall performance and the longevity of your LWS WHole Home Point of Entry Reverse Osmosis Water Purification System.

Question 15

What does 'Water Testing Recommended' mean?

Accepted Answer

For our Whole Home Point of Entry Reverse Osmosis Systems, a professional water test before installation to understand your specific water chemistry. This allows us to calibrate the system for optimal performance at your location.

Question 16

How long does it take to hear back after submitting a contact request?

Accepted Answer

Someone from our team will contact you within 48 hours of receiving your request.

Question 17

Do you offer a warranty?

Accepted Answer

Yes. We do offer a limited one year warranty, but more importantly, every system ships with our personal commitment to your long-term satisfaction. Contact us for full warranty details.
