Question 1

How long does an install take?

Accepted Answer

Most whole-home + RO installs finish in 4-6 hours. The whole-home unit ties into your main water line; the RO mounts under your kitchen sink. We pull the permit, our NC-licensed plumber does the tie-in, and you get your system up the same day.

Question 2

How much does the Complete Home System bundle cost?

Accepted Answer

$2,699 installed during founder pricing through July 31, 2026. That includes the whole-home softener + carbon filtration AND the HW800 AlkaPro under-sink RO drinking water system. After July 31 the bundle reverts to retail (~$5,998 of equipment + install).

Question 3

What's the warranty on the equipment?

Accepted Answer

Two distinct warranties: the equipment itself is covered by Honest Water Co's manufacturer warranty (terms vary by component — see HW warranty doc). Our installation work — fittings, drain integration, code-compliant routing — is covered by RWP's lifetime workmanship warranty. Both apply at the same time but cover different things.

Question 4

Why is chloramine in Triangle tap water?

Accepted Answer

Most Triangle utilities (Raleigh, Cary, Durham, Chapel Hill via OWASA) use chloramine instead of chlorine because it persists longer in the distribution system. You can taste it; standard carbon filters don't fully remove it. Catalytic activated carbon, used in our whole-home unit, does.

Question 5

Is there PFAS in Triangle drinking water?

Accepted Answer

Trace levels of PFAS have been detected in several Triangle utilities, especially those that draw from Cape Fear basin sources (Cary, Apex via Jordan Lake; Pittsboro). Levels are below current EPA enforceable limits but above the new 2024 health-based MCLs. NSF P473 certified RO systems remove 99%+ of PFOA/PFOS.

Question 6

Is Triangle municipal water actually hard?

Accepted Answer

No — Triangle municipal water averages 1.3-2.7 GPG (slightly hard or below). Raleigh Water draws from Falls Lake (~1.5 GPG); Cary draws from Jordan Lake (~1.7 GPG). The bigger municipal-water concerns are chloramine disinfection, trihalomethanes, and trace PFAS in some sources.

Question 7

Where does Oxford tap water come from?

Accepted Answer

City of Oxford draws from Lake Devin, a small in-city reservoir. Chemistry: free chlorine, moderate hardness. Because the reservoir is small relative to the served population, summer drawdown can concentrate dissolved organics and elevate trihalomethane (THM) precursors more than a larger-system like Raleigh would see.

Question 8

Why might Oxford tap water taste different at different times of year?

Accepted Answer

Lake Devin's small size means seasonal variation in raw-water chemistry shows up faster at the tap. Late summer typically brings higher dissolved-organic concentrations + the free-chlorine reaction that produces 'lake-y' taste compounds. The municipal system stays within EPA limits, but residents notice the variation. Whole-home catalytic carbon flattens the seasonality.

Question 9

Do older Oxford homes have lead pipe risk?

Accepted Answer

Yes — Oxford has the oldest housing stock of any Triangle city we serve. The historic district along College St, Hillsboro St, and the streets surrounding Oxford Orphanage contain substantial pre-1900 housing. Lead solder + occasional lead-lined service lines are real concerns. We test before quoting.
