Water Filtration & Water Quality FAQs

Even water that looks perfectly clear can carry dissolved minerals, chlorine or chloramine disinfection byproducts, trace metals, and — depending on your source — pesticides, PFAS ("forever chemicals") or bacteria. A free in-home water test is the only way to know exactly what's in your specific water, since it varies block to block and well to well.

It depends heavily on whether you're on a private well or municipal water. Homes on wells throughout Bucks, Montgomery, Chester and Delaware counties commonly deal with hard water, iron staining, sulfur odor and, in some cases, bacteria. Homes on municipal water (Philadelphia and the surrounding suburbs) tend to deal more with chlorine or chloramine taste and odor, moderate hardness, and aging-pipe issues like lead. We test for both sets of concerns, whichever type of water you have.

Hard water itself isn't considered a health hazard, but its side effects add up — scale buildup that shortens the life of water heaters and appliances, spots on dishes and glassware, dry skin and hair, and laundry that never quite gets clean or bright. Over the years, scale can also restrict flow inside your home's pipes.

A few common signs: spots or film on dishes and shower glass, dry skin or hair after showering, a chlorine or metallic taste, discolored or cloudy water, or a rotten-egg smell. That said, plenty of contaminants — like lead, PFAS or bacteria — have no taste, smell or visible sign at all, which is why we recommend starting with a free water test rather than guessing.

Filtration generally means removing specific things from water — sediment, chlorine, iron or hardness minerals, for example — often for the whole house. Purification, like reverse osmosis, is a more thorough, multi-stage process that strips out the broadest range of contaminants, typically for drinking water at one or more faucets. Most homes end up using a combination of both: whole-house filtration or softening for the entire home, plus an RO drinking water system at the kitchen sink.

Classic signs include white scale buildup around faucets and showerheads, soap that won't lather well, spots on dishes and glassware, and skin or hair that feel dry after washing. A free water test will give you an exact hardness reading in grains per gallon.

Traditional softeners use ion exchange — hard water passes through a resin bed that swaps calcium and magnesium ions for sodium ions. Our Chlor-A-Soft® system, designed for municipal water supplies, goes a step further by blending softening resin with carbon filtration media in one tank, so it also filters chlorine, chemicals and THM's/VOC's at the same time. Well water homes usually pair a standard softener with iron/sediment filtration instead, since there's no chlorine to filter out.

Yes. Softened water is safe for drinking, cooking and everyday use. The sodium added during softening is minimal — far less than what's in a typical serving of bread — though anyone on a strictly sodium-restricted diet should mention it to their doctor.

Not really. Most systems just need periodic salt refills, checked every few weeks and topped off as needed. Chlor-A-Soft® systems regenerate automatically on demand, so there's no manual cycling required.

True salt-based softeners actually remove hardness minerals from the water. Salt-free "conditioners" don't remove hardness — they alter its crystal structure so it's less likely to stick to surfaces, which helps with scale but won't give you the same soft-water feel on skin and hair. We install and service traditional salt-based systems for that more complete result.

Not on its own — a standard softener is built for hardness, not iron or sediment. If you're seeing iron staining, sulfur odor or sediment, that typically calls for iron/sediment pre-filtration ahead of your softener. We'll identify exactly what your water needs during your free test rather than guessing at a one-size-fits-all fix.

A whole-house (point-of-entry) filter treats every drop of water entering your home — showers, laundry, every faucet — while an under-sink or countertop filter (point-of-use) only treats water at one tap, usually the kitchen sink. Most households benefit from both: whole-house filtration or softening for the entire home, plus a dedicated RO system for drinking and cooking water.

Depending on what your water test shows, whole-house systems can target chlorine and chemical taste/odor, sediment and turbidity, iron and sulfur (well water), and general hardness minerals — often in combination, like our Chlor-A-Soft® system, which softens and filters chlorine/chemicals in one unit.

Not always. If your softener already includes carbon filtration media, like Chlor-A-Soft®, it's already handling both jobs for municipal water. Well water homes with iron, sulfur or sediment issues typically need a dedicated pre-filter installed ahead of the softener, since those contaminants can foul softening resin over time.

It depends on your water quality and household usage, but most whole-house filtration or softening media should be checked at least once a year. We're happy to set up a maintenance schedule when we install your system so nothing gets overlooked.

It depends on what your water needs — a single softener, an RO drinking water system, a UV sterilizer, or some combination. Because pricing depends on your home's plumbing, your water test results and which system(s) fit best, we don't quote pricing sight-unseen. We provide free, no-obligation pricing after your in-home water test.

Yes. We come to your home, test your water, walk you through exactly what we find, and recommend only what your water actually needs — there's no obligation to buy anything. Request your free water test here.

We serve Philadelphia, PA and the surrounding suburbs — Bucks, Montgomery, Chester and Delaware counties — plus South Jersey (Camden, Burlington and Gloucester counties) and New Castle County, DE.

It varies by product. For example, Chlor-A-Soft® water softeners carry a 20-year unlimited warranty, and our Sureflo® Superior RO systems carry a 5-year unlimited warranty (excluding consumable filters). We'll walk you through the specific warranty for whatever system fits your home.

In most cases, yes. Tell us the make and model (or send a photo of the unit) and we'll let you know what we can do — from resin/media replacement to full system diagnostics.

Most single-system installations — a softener, RO unit or UV sterilizer — are completed in a single visit. If you're combining multiple systems or need additional plumbing work, we'll walk you through the timeline during your free water test.
