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 Holly Springs water harder than Raleigh's?

Accepted Answer

Yes — significantly. Holly Springs buys water from Harnett County's Cape Fear River supply, which tests at ~2.7 GPG vs. Raleigh's ~1.5 GPG. That's still in the 'slightly hard' range, not the multi-state hard-water belt — but it's the hardest in the original Tier 1 Triangle launch cities. Softener payback is faster here than in Raleigh or Durham.

Question 8

Does Holly Springs water come from the same source as Raleigh?

Accepted Answer

No. Holly Springs buys finished water from Harnett County, not Raleigh Water. The source is the Cape Fear River — completely separate from Raleigh's Falls Lake supply. That's why hardness, disinfectant byproducts, and PFAS exposure all differ between the two cities even though they're 20 minutes apart.

Question 9

Are newer Holly Springs neighborhoods like 12 Oaks free of lead concerns?

Accepted Answer

Post-1986 communities — 12 Oaks, Sunset Ridge, Sunset Oaks, Holly Glen, Tara Ridge — were built after the federal lead-solder ban, so interior lead risk is minimal. The bigger concern in these neighborhoods is hardness (the highest in Tier 1) plus the Cape Fear basin PFAS exposure inherited from Harnett's source.
