Water filtration in Orange County, North Carolina

Orange County splits cleanly in two. The southern end has the towns and the municipal water. The rest, out past Hillsborough and up to the county lines, is rolling farmland and wooded lots where homes run on private wells.

A well here can need more than one kind of treatment, and when it does, the order the equipment goes in matters as much as the equipment. That is what this page is about.

What the water is like here

Piedmont well water usually brings some combination of sediment, low pH, iron and hardness, and on older or shallow wells bacteria can be a concern. Few wells have all of them. Plenty have two or three.

Each stage of treatment protects the one after it. Sediment comes out first so it cannot foul the tanks. Acidic water is corrected next, because low pH is hard on plumbing and on the equipment downstream. Iron is removed before softening. UV, if a well needs it, goes after everything else, since it only works in clear water.

The free in-home test is how we find out which of those stages your well actually calls for. Sometimes it is fewer than people fear.

We confirm your supplier and your source water during the free test rather than assuming it from your address.

What we actually find in Orange County

Stage one: sediment

A 5 micron Pre-Sediment Filter ahead of the main system. It is a small piece of equipment, and it keeps sand and silt out of everything downstream.

Stage two: pH, then iron and hardness

A Calcite Neutralizer raises acidic water toward neutral. It adds calcium as it works, so hardness may go up, which is one reason softening follows it. The Iron Breaker AIO then handles iron under 6 ppm and includes the softening tank.

Last stage: UV and the kitchen tap

Where bacteria is a concern, a UV purifier goes at the end of the chain. At the sink, a reverse osmosis drinking-water system comes free with every whole-home system.

In the towns

Homes on municipal water need none of this chain. Chlorine taste and smell is the common complaint, and a carbon filter for the whole house handles it.

Questions we get in Orange County

Do you work on well water?

Yes, and it's a meaningful share of what we do. Wells in Wake, Harnett, Chatham and Johnston counties commonly come back with iron, hydrogen sulfide, sediment or low pH. Those need genuinely different equipment than a city water home — which is why we test first instead of quoting off a price list.

Do I need a sediment pre-filter?

On a well, almost always. Sand, silt and grit will shorten the life of every piece of equipment downstream of it, including your pump and your pressure tank. On city water it’s rarely necessary unless you’re on an older line or there’s been recent main work.

What does a calcite neutralizer do?

It corrects acidic water. Low pH is common in NC well water, and acidic water slowly eats copper plumbing — the telltale sign is blue-green staining in sinks and tubs. A calcite neutralizer runs your water through crushed calcium carbonate, which raises the pH back to neutral. If your well tests acidic (the neutralizer is rated for inlet pH 5.0 to 7.0), this usually has to be handled before anything else.

When do I need a UV purifier?

Mostly when you’re on a private well and bacteria is a concern. UV light neutralizes 99.9% of bacteria and microorganisms without adding anything to the water. It’s an add-on at $400 installed, it needs clear water to work — sediment has to be filtered out ahead of it — and the bulb is replaced once a year. City water is already disinfected before it reaches you, so there it is extra assurance rather than a need.
