A Green UV G500 UV water-treatment system typically costs about $450-$850 for the equipment, with a midpoint near $625. A professionally installed setup commonly totals $750-$1,600, depending on plumbing access, prefiltration needs, local labor rates, and whether the quote includes startup testing.

Assumptions: U.S. retail estimates in USD; ordinary residential plumbing; no major electrical or water-treatment upgrades.
What a Green UV G500 system usually costs
The G500 price depends on whether the purchase is for the UV unit alone or a more complete treatment package. A reasonable equipment-only budget is $450-$850, averaging around $625; bundled listings may include mounting hardware, a replacement lamp, or basic filtration, while lower-priced listings may sell the UV unit without those extras.
With installation, many homeowners should budget $750-$1,600. This assumes the system can be connected to an existing water line, the installation area is accessible, and no substantial pipe rerouting is needed. Confirm the exact model, included lamp, controller, and shipping before comparing advertised prices.
UV treatment disinfects water but does not remove sediment, dissolved minerals, or chemical contaminants. The system’s rated flow and disinfection performance depend on the specific product configuration and water conditions, so buyers should verify the manufacturer’s specifications against household demand.
How the lamp, plumbing labor, and filters shape the quote
A contractor’s estimate usually combines equipment, installation labor, small plumbing materials, and any necessary water conditioning. Requesting an itemized quote makes it easier to spot whether filter housings, electrical work, testing, and disposal are included.
| Quote item | Typical price | What changes the charge |
|---|---|---|
| G500 UV unit | $450-$850 | Seller, package contents, shipping |
| Plumbing labor | $200-$550 | Access, pipe type, rerouting, local rate |
| Fittings and shutoff valves | $30-$150 | Pipe size and connection requirements |
| Sediment prefilter | $40-$250 | Housing, cartridge, and filtration capacity |
| Electrical or outlet work | $0-$250 | Whether a suitable outlet is nearby |
Labor can be estimated with . A straightforward connection may take 2-4 hours at roughly $75-$150 per hour, while difficult access or pipe changes can extend the visit. Ask whether the labor figure includes leak checks and system startup.
Flow rate, water clarity, and pipe access can raise the price
System sizing is a key cost and performance issue. Compare the G500’s documented flow rating with the home’s peak demand, not just average daily use. If the required flow exceeds the unit’s rating, a larger or different UV model may be needed, which can change both equipment and installation costs.
Water clarity also matters. Suspended sediment can shield microorganisms from UV exposure, so a sediment filter may be recommended when turbidity is above the equipment maker’s stated limit. Where water contains visible particles or heavy sediment, buyers may need additional filtration or treatment before the UV chamber.
Installation can cost more when the unit must fit in a cramped utility room, when pipe diameter or material requires special fittings, or when the main line needs rerouting. Adding more than about 10 feet of new pipe or moving the installation point can add roughly $100-$400, depending on materials and access. Have the installer verify flow, water quality, and connection dimensions before ordering.
DIY installation versus a plumber’s labor charge
A homeowner with compatible plumbing, a nearby outlet, and the required tools may avoid the $200-$550 labor expense. The work still requires careful placement in the water line, correct flow direction, secure connections, and a leak check. Electrical and plumbing work should follow applicable local rules and the manufacturer’s instructions.
Professional installation is more valuable when the main line must be cut, pipe routing is unclear, or the water system includes a pressure tank, softener, or other equipment. A plumber or water-treatment technician can also check whether prefiltration is appropriate. DIY savings are limited if an incorrect connection causes a leak or leaves the system poorly sized.
Why installed G500 quotes vary by U.S. location
Labor markets can shift the installed total even when the equipment price is similar. Urban areas with higher service rates may run about 10%-25% above a typical suburban estimate, while rural jobs can be 5%-20% higher when a contractor charges for long travel or has limited availability. These are planning differences, not fixed regional price rules.
Local plumbing codes and the home’s layout can matter more than the state or region. A simple connection near an existing outlet may stay near the lower installed range; a finished basement, remote utility area, or extra electrical work can push a quote upward. Compare at least two itemized local estimates using the same equipment and installation scope.
Replacement lamps and yearly ownership expenses
Budget about $90-$180 for a replacement lamp, with an average near $130, and check the manufacturer’s replacement interval for the exact G500 configuration. A quartz sleeve, if damaged or fouled, may add around $40-$100 for the part; labor to clean or replace it may be billed separately. Some units also use an alarm or controller that needs occasional inspection.
Over five years, lamp purchases alone may total roughly $450-$900 if the specified interval calls for annual replacement. That estimate excludes electricity, filter cartridges, and service calls. Use the required lamp and follow the service schedule rather than stretching replacement intervals to reduce short-term spending.
Which add-ons are worth including in the initial quote
Ask whether the quote includes a sediment filter, shutoff valves, bypass plumbing, startup, and disposal of packaging or an old treatment unit. A basic sediment-filter addition may cost $40-$250 for equipment, plus installation; more extensive filtration can cost several hundred dollars or more. The correct choice depends on water test results and manufacturer requirements, not a generic package upgrade.
Water testing may cost about $20-$150 for basic screening, with specialized laboratory tests costing more. If the source is a private well, testing can help identify issues that UV treatment alone will not address. Spend on testing or required pretreatment before paying for optional accessories that do not solve a documented water problem.
How to lower the G500 purchase and installation bill
Compare the complete delivered equipment price, not just the listing price. Check whether the lamp, controller, fittings, and warranty are included, and verify that the seller’s model number matches the intended G500 unit. A package that costs $50 more may be cheaper overall if it includes a required part that would otherwise be purchased separately.
Keep the installation near the existing main line and electrical outlet when practical, and schedule the work with other plumbing service if that avoids a separate minimum visit charge. Request separate prices for the UV unit, labor, filtration, and optional work. Do not pay for a higher-capacity model or elaborate filtration unless the flow requirement, water test, or equipment specifications support it.
