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 Cary tap water come from?

Accepted Answer

Cary draws from Jordan Lake via the Cary/Apex Water Treatment Plant. Hardness runs 1.5-1.8 GPG (soft to slightly hard), treated with chloramine. The key concern isn't hardness — it's 1,4-dioxane, an industrial solvent that arrives from upstream Haw River wastewater discharges and isn't fully removed by conventional treatment.

Question 8

Should Cary residents worry about 1,4-dioxane in tap water?

Accepted Answer

1,4-dioxane is a likely human carcinogen that's been detected in Cary's finished drinking water at levels exceeding EPA's health advisory of 0.35 ppb. It enters Jordan Lake from upstream industrial dischargers and resists conventional treatment. Activated carbon helps but isn't a complete fix — reverse osmosis is the most reliable household-level removal.

Question 9

Are newer Cary neighborhoods like Amberly or MacGregor at risk for lead?

Accepted Answer

Post-1986 homes (most of Amberly, Preston, MacGregor Downs, Carpenter, west Cary in general) carry minimal lead-solder risk since the lead ban took effect. The bigger concerns for new-construction Cary are the dioxane discussed above and chloramine taste — the whole-home catalytic carbon stage addresses both at every tap.
