WaterDrop G3P800 Tankless RO System with UV Sterilizing Light - Frequently Asked Questions

How often do I need to replace the filters and UV lamp?

The smart faucet display tells you when each filter needs replacing, usually every 6-12 months depending on use. The UV lamp lasts longer but should be replaced as indicated by the system.

Does the system require electricity to operate?

Yes, the G3P800 needs electricity for the UV light and smart faucet display. In a power outage, you lose the UV function, but basic filtration will still work temporarily.

Will this fit under a standard kitchen sink?

The tankless design is compact and fits easily under most sinks. I had no trouble fitting it with my cleaning supplies, but measure your space before purchasing.

Is the installation process beginner-friendly?

Installation is straightforward if you're comfortable with basic DIY. The instructions are clear, but drilling for the faucet and connecting the UV power may be challenging for some. Professional installation is an option.
