Why people call us about drinking water
Almost nobody calls asking for reverse osmosis. They call because of one of these.
The weekly trip to the water store
Refilling jugs, or hauling cases from the store and stacking them in the garage. It never ends, and somebody always has to carry them in.
The tap tastes like a swimming pool
Chlorine taste that comes and goes, so nobody in the house will drink from the sink and everyone reaches for a bottle instead.
You are paying for water twice
A water bill every month, plus cases of bottled water on top of it, plus the plastic piling up by the door.
Book your free water test
Twenty minutes at your sink. You keep the results either way.
How we do it
What happens when you call
From the first message to the last check. No surprises, no upsells.
1 
2 We come out and check it
If it's water, we test it at your sink and you keep the numbers. If it's outside, we measure. Either way you get the price in writing, on the spot.
3 We do the work
Same crew, and if you've got two problems we handle both. We mark utilities before we dig, and anything we touch goes back the way we found it.
4 We stay on the hook
10 years on equipment, 20 on gutters, and a year of service at no charge. In writing, not in conversation.
Our work, done right
What's included in our service
The unit lives inside the cabinet under your sink and ties into the cold line, out of the way. What you see on the counter is a slim faucet beside your regular one. Reverse osmosis strips minerals out along with everything else, so a remineralization stage puts them back and the water does not come out flat.
And this is only one of five things we do. Whole home filtration, fence, gutters and screen enclosures are the same crew, so whatever else the house is missing gets handled by the same people who already know your address.
- Free water test at your kitchen sink
- Installed under the sink, out of the way
- Its own faucet on the counter
- Filter changes at $200 when they are due
- Five services, one crew, one call

I never write reviews but the service I received from Yezenia was top tier. She knocked my door and not only had a great personality but made me excited to buy gutters and a water system for my first new home. Angel was the technician and WOW he was very educated on the quality of water needed specifically for my county. Highly recommend.

Wonderful experience with Melanie. She did an at home test of the water and explained the system thoroughly. Then followed up with me constantly to make sure everything was clear. Engel, who installed the filter, was outstanding, constantly checking in to make sure that everything was working properly. Highly recommend this company.

I was looking for a solution to the hard water in my home and Sulfur smell that I was getting. I'm grateful for the knock at my door. Jaylene did a great job with her demonstration and explaining The differences in the water purified versus the non-purified. When Angel came to install he also was able to answer any questions as well. Everything was really quick and easy.

So glad that we made the time to have our water tested! Found out just how hard our water really was out here despite having a water softener. With this Crystalline system, our water tastes better, smells better, and doesn't leave our skin feeling so tight and dry. They came out to retest our water and went over everything with us again which was much appreciated as well.

We had solicitations from several water softener companies, however we felt most comfortable and impressed with the presentation from Crystalline. Everything was as promised. The water is now awesome… no more bottled water.

Prefer to talk it through?
A real person answers, not a call center. Our team picks up seven days a week, 10am to 8pm, usually in under five minutes.
How to decide
Drinking water or whole house? Start here
A reverse osmosis unit treats one faucet, usually the kitchen sink. If the reason you are here is the taste or the cases of bottled water, that solves it. If it is also the smell in the shower, the spots on the glass or dry skin after a bath, that is a whole home problem and needs different equipment. The free test tells us which.
Straight talk on price
What does it cost?
You get the number in writing before anything starts and it does not move afterward. Filter changes once the system is in are $200, and we tell you when they are due instead of leaving you guessing. If you already own a unit and need it installed or moved to a new house, that is $450. Financing is available.
Straight answer
Is alkaline water better for your health?
We are not going to tell you it is. The research does not back it up and major medical sources say so plainly. What reverse osmosis actually does is take out what makes your water taste and smell bad, then remineralize it so it does not come out flat. Buy it because it tastes better than bottled and because you stop carrying cases. That is the honest reason.
CRYSTALLINE Plans & financing
Two ways to avoid the surprise bill
Every install already comes with warranties and a year of service you do not pay extra for. And when the number is bigger than the month allows, financing spreads it out.
Peace of mind. Built in.
Nothing here is an upsell. It is what comes with the job.
No extra cost
Included with every install
Written down, not promised in conversation.
- 10-year warranty on water equipment
- 20-year warranty on gutters
- One full year of service at no charge
- We come out and look within 24 hours
- A free water test at your kitchen sink
Estimate first
Financing options
Payment plans so it does not have to come out at once.
- Several lenders to choose from, not just one
- Terms in writing before you sign anything
- The estimate comes first and it is free either way
Financing is provided by independent lenders. We do not set rates or approve applications. Subject to credit approval.

Worth knowing
Drinking water and house water are two different jobs
A reverse osmosis unit treats the water at one faucet. It does nothing for the shower, the laundry or the dishwasher.
So if the reason you are here is the taste, this solves it. If the reason is also the smell in the shower, the white spots on the glass or skin that feels dry after a bath, that is a whole home problem and needs a different piece of equipment.
The free test tells us which one you have. Plenty of houses need both, plenty need one.

Good to know
Drinking water questions, answered
The things Central Florida homeowners ask us most about reverse osmosis and filters.
Will this make my whole house water better?
No. A reverse osmosis unit treats one faucet, usually the kitchen sink. The shower, the laundry and the dishwasher are a separate job and need whole home equipment.
Does alkaline water have health benefits?
We do not claim that it does, and the research does not support it. We install these because the water tastes better than bottled and because you stop buying and carrying cases. If a company promises you health results from water, take the rest of what they say carefully.
How often do the filters get changed?
It depends on your water and how much you use, which is part of what the test tells us. When it is time, a change is $200.
Does it take up my whole cabinet?
No. The unit mounts inside the cabinet under the sink and leaves most of the space usable. What you see on the counter is a slim extra faucet.
What if I already own a system?
We install it for $450, including if you are moving it from another house.
Is this the same as a filter pitcher?
No. A pitcher runs water through carbon and you refill it by hand. Reverse osmosis pushes water through a membrane that takes out far more, it lives under the sink, and it is on tap. The tradeoff is that it is plumbed in, so it is an install and not a purchase you carry home.
Does reverse osmosis waste water?
It does send some water down the drain while it filters, which is how the membrane stays clean. Newer systems waste less than older ones. If that matters to you, ask us and we will tell you what the one we install actually does.
How much room does it take under the sink?
The housings and the small tank sit against the back or the side wall of the cabinet. Most people keep using the space for cleaning supplies. We will look at your cabinet on the visit rather than guess.
Can I run it to the refrigerator?
Often yes, if the fridge line is reachable from where the unit goes. Ask us when we are there and we will tell you straight whether your layout allows it.
What if I rent?
Talk to your landlord first, because this ties into the plumbing. If they are fine with it, we can install it, and it can come out again when you leave.
