Reverse Osmosis · Randolph County, NC
Is It Healthy to Drink Reverse Osmosis Water in Randolph County?
People ask us this at the kitchen sink almost every week. Is it healthy to drink reverse osmosis water, or is something being taken out that you need? At Gunny's Plumbing, we install and service drinking water systems across Randolph County, and the short answer is that reverse osmosis water is safe for most households. The longer answer depends on your water, your family, and how the system is set up. Reverse osmosis, or RO, is one kind of point-of-use filtration. It sits apart from carbon-only filters, water softeners, and whole-house sediment units. Each one solves a different problem. A softener handles hardness. A carbon filter handles taste and chlorine. RO goes further and pulls out dissolved stuff the others leave behind. Below we go through what the membrane takes out, who should check with a doctor first, how well water and city water are different here, and how to keep the unit clean.
Reverse Osmosis Water Is Water With Almost Everything Filtered Out
Reverse osmosis pushes water through a very thin membrane using your home's own water pressure. The holes in that membrane are so small that most dissolved stuff can't squeeze through with the water. It all gets flushed down the drain instead.
That membrane grabs a long list of things. Lead from old solder joints. Nitrates, arsenic, sodium, PFAS, and the leftover byproducts from chlorine. But it doesn't stop at the bad stuff. Calcium, magnesium, fluoride, and trace minerals go out too, right along with everything else.
That's why RO water tastes different. Some folks say it tastes clean. Others say it tastes flat, because minerals are a big part of what you taste in regular tap water. It usually takes a few days to get used to.
Most of the units we put in around Randolph County are small under-sink systems with their own little tap next to the main faucet. Nine times out of ten, that's the right call here. You're only treating what you drink and cook with, not the water running your washing machine.
Drinking RO Water Is Safe for Healthy Adults and Kids
Yes. Reverse osmosis water is safe to drink every day for healthy adults and kids. The minerals in your drinking water are a small piece of what your body takes in compared to food. Milk, greens, beans, and nuts do a lot more of that work than your tap water ever did.
A few people should ask a doctor first:
Older research, including World Health Organization work on water with very low mineral content, raised some questions worth knowing about. For a typical family eating a balanced diet, though, it hasn't changed how we talk to people here. If you want to read the background yourself, the WHO keeps its material on drinking water quality public.
One thing we point out on every install: fluoride goes out with everything else. If your kids were drinking fluoridated city water before, mention the switch to your dentist. A toothpaste or rinse usually takes care of it.
- Parents mixing infant formula - ask your pediatrician which water to use
- Anyone on a low-mineral or restricted medical diet - check with your doctor
- Households already taking mineral supplements - your doctor can adjust
Well Water and City Water in Randolph County Call for Different Filters
A lot of homes out toward Seagrove, Staley, and Franklinville run on private wells. That water comes up through Piedmont granite and heavy clay. What we usually find in it is hardness, iron stains, fine sediment, and sometimes manganese that leaves a dark streak in the toilet tank.
Wells near old pasture, fertilized fields, or an aging septic line are the ones that worry us most. Nitrates and bacteria belong on your test list. Get the water tested before anyone sells you equipment. RO alone won't fix a bacteria problem, and we're not going to tell you it will.
City taps in Asheboro, Archdale, and Randleman tell a different story. That water's treated and monitored, so the complaint is usually just taste. Chlorine or chloramine comes through strong, especially late in summer.
Once the cover's off an untreated well system, the pre-filter is often packed solid with orange grit. That tells us more than any brochure ever could. Match the filter to the test results, not to the sales pitch.
Remineralizing and Blending Put Taste and Minerals Back
If that flat taste bugs you, there are three common fixes. A remineralization cartridge sits after the membrane and feeds calcium and magnesium back into the finished water. It's a small inline part, and it gets swapped along with the rest.
An alkaline post-filter does something similar while nudging the pH up a bit. Folks who drink a lot of water straight from the tap tend to notice this one first. A blending valve is the simplest fix. It just lets a small trickle of untreated water mix back into the stream.
For most households around here, diet already covers the minerals your body needs. So this really comes down to taste, not health. Pick based on three things: how the water tastes to you, what your test report shows, and who in the house actually drinks from that tap.
When a family's well water is loaded with iron, we usually skip blending altogether. Letting that water back in just defeats the whole point of the system.
Filter Changes and Sanitizing Keep RO Water Clean
An RO unit isn't something you set up and forget. The sediment and carbon pre-filters need changing on a schedule, usually once a year on city water. The membrane itself lasts a lot longer, since those pre-filters are there to protect it.
You'll know when it's due. The tank fills slower than it used to. The taste starts drifting back toward tap water. Pressure at the little faucet drops to a dribble. Hard well water chews through pre-filters faster, which is why we often put a softener ahead of the unit on well systems around the county.
When filters come out, the tank and lines need sanitizing too. Skipping that step is the mistake we end up fixing most often. Bacteria will happily move into a tank that hasn't been cleaned in a while, and fresh filters don't do a thing about that. We also check the drain line and tank air pressure once a year. A tank with low air pressure gives you half a glass and then quits on you.

The Bottom Line
Reverse osmosis water is safe and healthy for most people in Randolph County. It takes out lead, nitrates, PFAS, and chlorine taste, and it takes minerals and fluoride with them. Food covers those minerals for nearly everyone. Parents mixing formula and anyone on a special diet should ask their doctor first.
Start with a water test, then match the system to it. Learn more about how these systems work on our reverse osmosis page, or call Gunny's Plumbing.
Common questions
Is reverse osmosis water bad for your kidneys?
No. There's no good evidence that reverse osmosis water harms healthy kidneys. Your kidneys deal with the mineral load from food, not from drinking water. If you have kidney disease or are on a restricted diet, ask your doctor what they want you drinking. That's worth asking about anyway, since it covers sodium and potassium from everything else you eat too.
Does RO water in Randolph County strip out the minerals my body needs?
It does remove calcium, magnesium, and other trace minerals from the water, yes. But drinking water was never a big source of them to begin with. Food carries far more. For most families in Randolph County, a normal diet covers it just fine. If you still want minerals in your glass, a remineralization cartridge after the membrane puts calcium and magnesium right back in.
Can I use reverse osmosis water for baby formula here in Randolph County?
Ask your pediatrician first. Plenty of parents do use reverse osmosis water for formula, since it's low in nitrates, lead, and sodium. The thing worth mentioning is fluoride, which RO removes. Your pediatrician may have a preference based on your baby's age and what else they're drinking. That's not a call we'll make for you.
Does reverse osmosis take the fluoride out of Randolph County water?
Yes. The membrane removes most of the fluoride along with the other dissolved minerals. If you're on city water in Asheboro or Randleman and your family counted on that fluoride, let your dentist know you've switched. A fluoride toothpaste or prescribed rinse usually handles it, especially for kids. Well owners rarely notice a change, since most private wells were never fluoridated to begin with.
Is RO water better than bottled water?
For most households, yes, and it costs less over time too. Bottled water quality varies a lot by brand, and you're hauling cases home every week. An under-sink reverse osmosis unit gives you filtered water on demand right at the tap. You trade the cases for a yearly filter change, which takes us well under an hour.
How often do reverse osmosis filters need changing?
Sediment and carbon pre-filters usually run about a year; the membrane often goes two to five. Well water with iron or heavy sediment shortens that noticeably. Watch for a slow-filling tank, dropping pressure, or taste creeping back in. Those are the signs we hear about most. Call us and we'll swap the filters and sanitize the tank.
