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

How many PFAS compounds has OWASA detected in Chapel Hill drinking water?

Accepted Answer

OWASA has documented at least 9 distinct PFAS compounds in finished drinking water, including PFOA, PFOS, PFHpA, PFHxS, PFBS, and several others. Levels are below current EPA enforcement thresholds for most compounds but above the more conservative health advisory levels. RO at the drinking tap is the most reliable household removal.

Question 8

Where does Chapel Hill tap water come from?

Accepted Answer

OWASA (Orange Water and Sewer Authority) sources from Cane Creek Reservoir and University Lake. Both are within the OWASA system and feed the Mason Farm Water Treatment Plant. Hardness runs 1.5-1.8 GPG (soft to slightly hard) treated with free chlorine — the PFAS detections are the dominant quality concern, not hardness.

Question 9

Do rental homes near UNC campus need different filtration?

Accepted Answer

Pre-1986 rentals in Northside, Pine Knolls, and the older blocks of Westwood may have lead solder; the broader OWASA PFAS issue affects all customers regardless of housing era. For tenants we recommend an under-sink RO that doesn't require a permanent install — landlord buy-in usually isn't needed, and it removes both lead-at-tap and PFAS.
