Across most of the state, tap water comes out of limestone and arrives loaded with dissolved calcium and magnesium. That's what scales your pipes, wears out your water heater early, and leaves film on everything you own. We fix it where the water enters the house.
Chalky scale on spouts, shower doors and glassware that returns days after you scrub it off.
No hardness minerals in the water means nothing left behind to dry into scale. Wipe once, and it stays clean.
Minerals bind to soap instead of letting it foam, so you use more shampoo and more detergent for the same result.
In controlled testing, softened water cut the detergent needed for the same clean by up to half in laundry and up to 70% in dishwashing.
Soap curd and mineral residue stay behind on your skin after every rinse, which is why lotion feels compulsory here.
Nothing left on your skin but water. This is the change most customers mention first, usually within the first week.
The disinfectant that keeps municipal water safe is also what you taste in your coffee and smell in the shower.
Stage two runs the softened water through activated coconut shell carbon, which is what removes chlorine taste and odour.
Scale settles on the tank floor and the burner surface. Gas heaters measurably lose efficiency as it accumulates.
The same lab study measured 1.16 lb of scale a year in a gas heater on hard water — and 0.02 lb on softened water. Effectively none.
Shampoo and hard water make a curd that stays in your hair instead of going down the drain. It builds up as a dull film, and no amount of rinsing shifts it.
Nothing dissolved in the water means nothing left in your hair. Shampoo rinses out completely, so hair feels soft rather than coated and holds its shine between washes.

OtterSoft Water
Otter Soft Water is part of the UDI family, alongside UDI Water and United Hydro. Three names, one company, and water is all we do. The technicians who install your system are our own employees — and they're the ones who come back when it needs attention in year eight.
A whole-home conditioner is the fix for hardness, and it's where nearly every customer starts. A drinking water system is the upgrade for taste and purity at the kitchen sink.

Three units in one tank. Water is softened through cation resin, refined through activated coconut shell carbon, then polished through a silica filter bed — every drop, every tap.
A reverse osmosis unit under the kitchen sink for the water you drink and cook with. The softener handles the whole house; RO gives you one tap of near-pure water. Sold separately from the Pro Plus — it is not included in the softener’s installed price.

Tell us who you are and when suits you. A local Otter technician calls to confirm, then brings your price in writing — before you spend $THOUSANDS more at the national brands.
Yes. A technician tests your water at the tap, explains the results, and leaves. There's no fee and no requirement to buy anything. We do it because most people have no idea how hard their water is until they see the number.
Usually, yes. Municipal utilities treat water for safety — bacteria, contaminants, disinfection. Hardness isn't a health issue, so it generally isn't removed. That's why city water in Florida still leaves scale on your fixtures. JEA, the City of Tampa and OUC all publish their own hardness numbers, and all three are in the hard or very hard range.
A softener treats the whole house and removes the calcium and magnesium that cause scale, film and appliance wear. Reverse osmosis treats one tap — usually the kitchen sink — and improves taste and purity for drinking and cooking. They solve different problems and work well together.
It depends on your water, the size of your home, and whether you add drinking water. What we can tell you now is that the Pro Plus lands thousands less than the national brands for a comparable install — the comparison table above shows their figures. We won't quote your number sight unseen, and we won't make you sit through a presentation to get one — you get it in writing after the test.
Most whole-home installs are completed in a single visit, typically about half a day. Adding an under-sink RO system usually adds an hour or two.
Installation requires the property owner's authorization, since the system connects to the home's main water line. If you rent, we're glad to talk to your landlord.
