Pricing

What moves the cost of water filtration

A pitcher refill and a whole-house system are different scales of job. Ask about pricing when you call.

Kind of system

Under-sink carbon is a small job. A whole-house carbon tank with a bypass is bigger. Reverse osmosis adds a tank and a drain.

Pipe size and material

Larger lines and mixed materials need adapters and sometimes new fittings.

Where the unit goes

A clear wall by the main shutoff is simple. A cramped crawl space is slower.

Drain and power

Reverse osmosis and backwashing units need a drain. Some need an outlet.

Cartridges and upkeep

Filters wear out. The change interval and cost of cartridges belong in the decision.

Know your water

Water filtration in Greer starts with knowing your supply

A filter should match what is in the water. A few local facts and one test can save a wrong purchase.

What does the local utility say about the water?

Greer CPW supplies the City of Greer and surrounding areas, treating surface water from Lake Cunningham and Lake Robinson, both fed by the South Tyger River. Its 2025 Water Quality Report lists no violations and a chlorine and ammonia combination, called chloramine, as the disinfectant. Not every address in the Greer area is on that utility, so check your bill or ask your water provider who serves yours.

Learn your supply first

Read the annual reportUtilities publish a water quality report each year. Your provider can send the latest.
Look at your billIt names the provider and often the service area.
Ask about hardnessHow much mineral your water carries depends on your address. Ask your provider.
Test if unsureA lab test for the exact thing you are worried about beats a guess.
Note any noticesBoil or advisory notices come from the provider, not from a filter seller.

A short list of homework that makes the choice easier.

The utility also states that it has no known lead service lines in its system, and its service lines are copper, galvanized iron, PEX and PVC. Plumbing inside a home is separate from the service line, and fixtures or older solder can still matter, so a home with old pipes may want its own test. Our guide on signs of corroded pipes shows what aging lines look like.

What to remove

What water filtration in Greer can and cannot remove

No filter does everything. Each type targets a few things and leaves others alone.

Look for a filter tested to the standard for the thing you want to reduce.
Complaint	Filter that targets it	What it will not fix
Chlorine or chloramine taste and smell	Carbon block or catalytic carbon	Hardness minerals
Sand, silt, rust flakes	Sediment cartridge, often 5 to 20 micron	Dissolved minerals and chemicals
Scale and spotting	A softener, not a filter	Taste
Iron staining	Iron filter or a softener tuned for iron	Bacteria
Dissolved salts and many trace contaminants	Reverse osmosis at one tap	Water for the whole house
Microbes from an untreated source	UV or purpose-built treatment	Chemicals and taste
Lead from fixtures or old solder inside a house	A filter built and tested for lead, at the kitchen tap	Anything it is not tested for

Chloramine is harder to remove than plain chlorine. Standard carbon works slowly on it, and catalytic carbon or longer contact time does better. If chloramine taste is your complaint, say so on the call so the plumber picks accordingly. A water softener is a separate device for scale.

Systems

Whole-house, under-sink and reverse osmosis: which fits?

The three families differ in cost, space and what they treat. This table lines them up.

These are common families, not a complete list.
System	Where it goes	Best for	Watch for
Whole-house carbon	On the main line after the shutoff	Taste, smell and chlorine in every tap and shower	Needs room, a bypass and a cartridge or media change schedule
Whole-house sediment	At the main, ahead of everything else	Grit and rust flakes reaching appliances	Clogs fast in dirty water and drops pressure
Under-sink filter	Cold line below the kitchen sink	Drinking and cooking water	Cabinet space and a separate tap
Reverse osmosis	Under the sink with a small tank	The cleanest drinking water	Wastes some water to drain and needs a drain connection
Refrigerator line filter	Inside the fridge or on the supply line	Ice and cold water only	Small cartridge, regular changes
Showerhead filter	On the shower arm	Chlorine smell in the shower	Limited capacity, replace on schedule

Is whole-house filtration worth it?

A whole-house system treats the water at the main, so every tap and appliance gets it. That helps if chlorine smell bothers you in the shower or if grit is hitting washing machine screens. It also costs more and needs a good spot near the main. For drinking water alone, an under-sink system covers the kitchen at a much smaller scale.

Quick picker

Whole houseChoose when the whole home has the same issue.
Under sinkChoose when only drinking water matters.
BothMany homes use a sediment filter at the main plus a carbon unit under the sink.
NoneIf the water is fine to you and your provider’s report is clear, skipping a filter is a valid choice.

Match the system to the complaint.

Filter or softener

Do I need a filter, a softener or both?

The two do different jobs. People often buy one when they needed the other.

What does a softener do that a filter doesn’t?

A softener swaps hardness minerals, mostly calcium and magnesium, for sodium or potassium. That stops scale on fixtures and in the water heater. A carbon filter does not touch those minerals. A filter handles taste, odor and particles. A house with both complaints may need both, installed in the right order.

What each device handles

Common pairings.
If you see	Think about
Chalky white crust on faucets	A softener
Chlorine smell and taste	A carbon filter
Grit in aerators	A sediment filter
Scale in the water heater	A softener, and a flush of the tank
Both scale and taste	A softener plus a carbon unit

How hard your water is depends on your address, so check your bill or ask your water provider. If scale is already clogging a tank, our water heater flushing guide shows the usual steps, and water heater repair covers parts that have already failed.

Installation

How a whole-house filter is installed

The unit is simple. The plumbing around it is what makes it service-friendly.

Pick the spot
Just after the main shutoff and meter, before any branch, with room to reach the cartridge.
Shut the water and drain the line
The main is closed and the lowest tap opened to empty the pipe.
Cut in the unit with shutoffs
A valve goes on each side, plus a bypass loop so water keeps flowing during a change.
Purge and test
Air is bled out, fittings are checked for drips and flow is measured at a few taps.

The tie-in also tests the main shutoff. Many homes find the valve stuck or leaking. The guide on how to shut off your main water valve explains how to locate it, and a failing valve can be replaced in the same visit.

Upkeep

Keeping a filter working: cartridges, flow and leaks

A filter that is never changed is worse than no filter. A short routine keeps it useful.

How often do cartridges need changing?

It depends on the filter and the water. Sediment cartridges clog on their own schedule, carbon cartridges lose their ability to adsorb, and reverse osmosis has several stages with different lifespans. Follow the maker’s interval, and change sooner if the pressure drops or the taste returns. Mark the date on the housing.

Maintenance

Date the housingA marker on the canister tells you when the last change was.
Watch the flowA clear drop at the tap means a cartridge is clogging.
Check the O-ringA pinched or dry O-ring is the usual cause of a drip. Wipe and lightly grease it.
Hand tighten onlyA wrench can crack a housing.
Use the bypassIt lets you change a cartridge without cutting water.

Five habits that avoid most filter problems.

What should I do if the housing leaks?

Close the valves on each side and open a nearby tap to relieve pressure. Check the O-ring, the cap threads and the fittings. A cracked canister must be replaced. In a basement, crawl space or garage, a slow drip can run a long time before you see it, so look at the floor under the housing after each change.

Where leaks start

Close the valves first.
Leak at	Likely cause	Fix
Cap seam	Dry or pinched O-ring	Re-seat with lubricant
Inlet or outlet fitting	Loose fitting or thread tape	Re-seal the thread
Bottom of canister	Cracked housing	Replace the canister
Pressure relief button	Pressure built up	Open it briefly, then check the O-ring

A drip that does not track to the filter might be part of a bigger problem. Leak detection finds hidden sources, and slow flow throughout the house is covered under low water pressure.

Questions

Water filtration in Greer: common questions

What does a water filtration system do?

A water filtration system removes particles, chlorine taste and some chemicals from your water as it passes through a cartridge or tank. The result depends on the filter type. Carbon improves taste, sediment catches grit, and reverse osmosis removes many dissolved substances at a single tap.

Do I need water filtration in Greer?

That depends on what bothers you and what your provider’s report shows. Water filtration in Greer is common for taste and smell, and optional for water that already tastes fine. Your water bill names your provider, and the provider can share its annual report with you.

Is there chloramine in Greer water?

Greer CPW’s 2025 Water Quality Report lists a chlorine and ammonia combination, which is chloramine, as its disinfectant. Not every address in the Greer area is on that utility, so check your bill or ask your water provider. If it is chloramine, catalytic carbon handles it better than standard carbon.

What is the difference between a filter and a softener?

A filter removes taste, odor and particles. A softener replaces hardness minerals to stop scale. They solve different problems, and many homes use both. If white crust on fixtures is your complaint, a softener is the answer. A filter will not stop it.

How much does water filtration cost in Greer?

Cost depends on the kind of system, the pipe size, the location, any drain or power connection and the cartridges you will buy later. Ask about pricing when you call and describe what you want to fix. The price section above lists each factor.

Is a whole-house filter better than an under-sink filter?

Neither is better in general. A whole-house filter treats every tap and appliance, which helps with chlorine smell in showers. An under-sink filter treats only the kitchen drinking line at a smaller cost. Many Greer homes use a sediment filter at the main and a carbon filter at the sink.

How often should I change the filter cartridge?

Follow the interval printed on the filter, and change sooner if flow drops or taste returns. Sediment cartridges can clog quickly in cloudy water, while carbon cartridges lose their strength gradually. Write the install date on the housing so you do not have to remember.

Will a water filter reduce my water pressure?

A clean filter of the right size barely affects pressure. A clogged cartridge or an undersized housing does. If pressure falls after a filter goes in, change the cartridge first. If that does not help, a plumber in Greer can check the housing size and the pipe behind it.

Can you install water filtration the same day?

Same-day service is available for water filtration in Greer, and the line is open 24/7. A simple under-sink or main-line unit can often go in during one visit. Reverse osmosis and whole-house systems may need a drain or electrical check, which the plumber explains on the call.

What should I do if my water looks brown or cloudy?

Run the cold tap for a few minutes to see if it clears. If it clears, it was likely disturbed sediment. If it stays brown or you have a notice from your provider, stop drinking it and call your water provider. Call a plumber about discolored hot water only.

Does a water filter protect against lead?

Only a filter built and tested for lead does. Greer CPW states it has no known lead service lines, but plumbing inside a home is separate. Older solder or fixtures can still carry lead, so a home with old pipes should test its water and ask a plumber about a tested filter.
