About Irvine Water Systems

A residential water treatment company that sizes every system to the water in front of it, and explains every part before you decide.

Why we do it this way

Irvine Water Systems began with a simple observation: most people who buy water treatment never see what is in their water first. They see a demonstration, hear a price and sign. We wanted to do the opposite, starting every conversation with a free water report and letting the results decide what, if anything, gets installed.

That approach fits Irvine well. The city's neighborhoods are full of homeowners who read the fine print and ask good questions, and we would rather answer those questions properly than talk around them. Across Irvine and the neighboring cities, our work runs from a single filter under a kitchen sink to full treatment on a main line.

Today the company stands for three things: water that is tested before it is treated, prices that are settled on paper before work starts, and installations that are explained so clearly you could describe them to a neighbor.

What we are here to do

Our job is to make the water in your home better in the ways that matter to you, and not to sell you more equipment than your water calls for. Sometimes that means a whole-house system. Sometimes it means an under-sink filter. Occasionally it means telling you your water is fine as it is.

How we work

Results before recommendations

Nothing is suggested until we have looked at what your supply carries and what you are seeing at home.

Plain explanations

You will understand what each part of a system does and why it is there, without a wall of jargon.

Sized, not stocked

Equipment is chosen for your household's water and use, not from whatever happens to be on the shelf.

Questions welcome

Ask as many as you like. Good questions make for better installations, and we would rather answer them now than after the fact.

Upkeep made clear

Every system comes with a written schedule for filters, media and service, so nothing gets forgotten.

Room to decide

You can take the report and the price away and think it over for as long as you like.

Where you will find us

We work across Irvine, Tustin, Santa Ana, Orange, Costa Mesa, Newport Beach, Lake Forest, Laguna Hills, Laguna Woods, Aliso Viejo, Mission Viejo and Laguna Niguel.
