Ultraviolet (UV) disinfectionThe Serval Package
An ultraviolet (UV) light system that disinfects water as it flows past a lamp: Charger Water’s CWUV4 series, sized to your home’s flow. It adds nothing to the water and takes nothing out. $1,875 installed — a reference price: not bookable until CreekWell’s contractor licenses are issued. Treats: A germ barrier for water that tests free of coliform (UV; not NSF/ANSI 55 certified)
Warranty: Reactor 10 years · electronics 3 years · lamp and sleeve 1 year
Before you choose
- Not certified: it is not certified to NSF/ANSI 55, the standard for UV units. Ohio’s health department says UV units without that rating are not intended for water that is microbiologically unsafe (water with harmful germs in it); certified Class A units are.
- Needs: the lamp runs all the time, so it needs an outlet that is always on.
- Limits: Charger’s UV needs water under 7 grains of hardness and 0.3 ppm of iron. ADEQ’s Prescott-area wells averaged about 12 grains, so many wells need a softener or iron filter ahead of it, priced as its own package (see More than one problem?).
- Upkeep: the lamp is replaced every year.
Words like grain, backwash and NSF/ANSI are explained in the plain-words list.

Every package sheet uses these same rows in the same order, so you can compare them line by line. “Our arithmetic” marks a figure we worked out from the makers’ numbers.
What it is
An ultraviolet (UV) light system that disinfects water as it flows past a lamp: Charger Water’s CWUV4 series, sized to your home’s flow. It adds nothing to the water and takes nothing out.
Good fit if
- You want a barrier against germs in a private well whose water tests safe today.
- Your water is clear and inside the UV limits — or will be after the filters ahead of it.
- If a test has found coliform or E. coli, the source is found and fixed first. Ohio’s health department says water that is not safe to drink calls for an NSF/ANSI 55 Class A unit, and this is not one.
It will not
- Remove chemicals, arsenic, nitrate, iron or hardness. UV only disinfects.
- Protect water after it leaves the unit. UV leaves nothing behind in the water, so the plumbing after it can be recontaminated (University of Nebraska).
- Work on cloudy, hard or iron-stained water — that needs treatment first.
What’s in the package
- UV system
- Charger Water CWUV4 whole-house model, sized to your peak flow: CWUV4-6, -11, -15 or -21. They are rated 6, 11, 15 and 21 gpm at Charger’s standard dose (30 mJ/cm²), or 4.4, 8.3, 12 and 16 gpm at the stronger 40 mJ/cm² dose that NSF/ANSI 55 Class A uses — both with very clear water (95% UV transmittance).
- What is in the box
- A polished 304 stainless-steel reactor with a sight port to check the lamp is on, the lamp and its quartz sleeve, and a controller with a lamp-life countdown and sound and light alarms for a failed or worn-out lamp (Charger). Charger lists no UV-intensity sensor.
Written on your estimate before you approve anything:
- The model size for your home’s flow, and the lamp and sleeve prices
Certification
- Charger’s CWUV4 sheets make no NSF/ANSI 55 claim. NSF/ANSI 55 Class A requires a 40 mJ/cm² dose with an alarm or automatic shutoff (Ohio Department of Health).
Sized for
- By your home’s peak flow and the dose you want (the four models are under What’s in the package). The stronger dose means a bigger model for the same flow.
- The flows above assume very clear water (95% UV transmittance). Charger allows water down to 75%; the less clear the water, the bigger the model for the same dose, so the size comes from your lab’s UV transmittance reading.
Flow
- CWUV4-6, -11, -15 and -21: 6, 11, 15 and 21 gpm at Charger’s standard dose (30 mJ/cm²), or 4.4, 8.3, 12 and 16 gpm at the stronger 40 mJ/cm² dose, with very clear water (Charger). Operating pressure 10–150 psi (Charger).
- For scale: a shower head uses up to 2.5 gallons a minute (gpm) and a kitchen faucet up to 2.2 gpm (federal limits, EPA).
Water it can handle
- Charger’s conditions for use, to check against your lab report:
Charger conditions for the CWUV4 In your lab report Must be Hardness under 7 grains (120 ppm) Iron under 0.3 ppm Manganese under 0.05 ppm Tannins under 0.1 ppm Turbidity (cloudiness) under 1 NTU UV transmittance (how clear the water is to UV light) over 75% - Water temperature 36–104°F (Charger).
- Ohio’s health department: treat the water first when iron is 0.3 ppm or more and hardness 6 grains or more.
What it uses
- Salt: none. Water: none.
- Electricity: 30 to 62 watts, all day, by model (Charger) — about 260 to 540 kilowatt-hours a year (our arithmetic).
Space and hookups
- A reactor about 2½″ wide and 21″–40″ long by model (the -21 is 3½″ wide), and a small controller (6.8″ × 3.6″ × 4″).
- An outlet that is always on.
- No drain.
- The controller comes in a splash-proof case (Charger).
Sodium
- None added.
Upkeep: yours and ours
| Task | How often | Who |
|---|---|---|
| UV lamp | Every year. Charger rates the lamps at 9,000 hours, just over a year, and Ohio’s health department says to change them yearly even if they still glow. Price on your estimate. | Neil, or you |
| Quartz sleeve | Charger sells a replacement sleeve for each model; price on your estimate | Neil |
| Alarm | If the controller beeps, the lamp has failed or is due | You call Neil |
Price
$1,875 installed, flat, anywhere in Yavapai County. Arizona sales tax on the parts is already in that price (CreekWell’s invoice terms). What is not included is listed below.
Not bookable yet. This work costs more than $1,000, which puts it outside what CreekWell can take on until its Arizona contractor licenses are issued. The details here are accurate so you can plan and compare. Why not yet?
Included
- Installation last in line, after any filters and softener
- Testing before Neil leaves
- CreekWell’s two-year workmanship warranty
Not included
- Pretreatment if your water is over the UV limits
- Bacteria test before and after (see Testing)
- Replacement lamps and sleeves
- An always-on outlet if none is close enough — electrical work, arranged separately
- New loop plumbing, if your home has no place to connect it — quoted flat and approved by you first
Running costs
- A new lamp every year, and a sleeve now and then (prices on your estimate).
- Electricity: 30–62 watts all day — about 260–540 kilowatt-hours a year (our arithmetic).
- Neil has not published prices for this package’s replacement parts yet; your written estimate lists today’s prices before you approve anything.
Paying
- A 50% deposit sets the install date; the rest is due when it is in and tested.
- The written estimate is good for 30 days. If you cancel after the three business days the FTC’s Cooling-Off Rule gives when you sign at home, what happens to the deposit (for example, parts already ordered for you) is written on the estimate before you sign.
- Zelle, cash or check: no fee. A card fee, if you pay by card, is shown as its own line on the estimate (payment terms).
Warranty
| Part | Coverage | Who |
|---|---|---|
| UV reactor | 10 years (limited) | Charger |
| UV electronics | 3 years (limited) | Charger |
| UV lamp | 1 year (limited) | Charger |
| UV quartz sleeve | 1 year (limited) | Charger |
| The installation (the work itself) | 2 years — CreekWell’s warranty terms | CreekWell |

- Who pays the labor to take out a defective part and fit the new one, in the first two years and after, is written on your estimate.
Testing and follow-up
- Before: a certified bacteria test (SimpleLab’s Level 1 + Bacteria, $185 at its price, includes total coliform and E. coli) and the water items above.
- After: a bacteria retest after installation shows whether it is working (University of Nebraska: test for the problem after installing). Not included.
Code and permit notes
- Installed last, after any filters and softener.
- An always-on outlet, not on a switch.
- The City of Prescott has adopted the 2024 International Plumbing Code; the county and other towns set their own.
- If a particular job turns out to need a permit, you are told before any work starts.

What happens next
- Join the list — free, no deposit. Whole-house installs wait until CreekWell’s contractor licenses are issued; the list is how you hear first.
- Once the licenses are issued, Neil calls in the order names came in and sets a free visit: a check of hardness, chlorine and total dissolved solids, and a look at your loop, drain, outlet and space. On a well, the lab test comes first.
- You get a written flat-rate estimate, with every “written on your estimate” item on this sheet filled in. If your test points to a different package, the estimate is written for that one. Nothing is ordered until you approve it.
- Approving an installation: a 50% deposit sets the date; the rest is due when it is in and tested. How long the parts take to arrive, and so your install date, is on your written estimate. If you sign at your home, the FTC’s Cooling-Off Rule generally gives you three business days to cancel.
- Install day: how long it takes, and how long your water is off, is on your estimate. Replacement installs include haul-away of the old unit, and everything is tested before Neil leaves.
CreekWell is not a licensed contractor. Work is performed under the Arizona handyman exemption, A.R.S. § 32-1121(A)(14): any single project is limited to less than $1,000 including labor and materials, and excludes work requiring a building permit and all natural gas and propane work.
