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

Is Carrboro water the same as Chapel Hill's?

Accepted Answer

Yes — Carrboro and Chapel Hill both purchase finished water from OWASA, which means identical source (Cane Creek Reservoir + University Lake), identical treatment (free chlorine), and identical PFAS exposure across at least 9 documented compounds. There's no meaningful difference between Carrboro and Chapel Hill tap water chemistry.

Question 8

Should Carrboro residents prioritize PFAS filtration?

Accepted Answer

Yes. OWASA has documented PFOA, PFOS, and 7 other PFAS compounds in finished drinking water at levels above the EPA's revised 4 ppt enforcement threshold for PFOA/PFOS. Reverse osmosis at the kitchen sink is the most reliable household removal (95-99% reduction); whole-home carbon helps but doesn't match RO performance for PFAS specifically.

Question 9

Do older homes in north Carrboro have lead pipe risk?

Accepted Answer

Pre-1986 homes north of Main St and around Lloyd-Broad area may have lead solder in interior plumbing. OWASA's finished water is treated to limit leaching, but house-side conditions vary. For any pre-1986 Carrboro home, RO at the drinking tap handles both lead and the broader PFAS exposure.
