Pentair Freshpoint GRO-350 Installation

The Pentair Freshpoint GRO-350 is a compact tankless RO designed for straightforward under-sink installation in 45--90 minutes. Unlike APEC or iSpring systems with multiple separate filter housings, the Freshpoint's filters are integrated into a single compact unit (approximately 12" x 6" x 15"). The system includes a dedicated brushed nickel faucet and all connection hardware. Pentair recommends professional installation for the GRO-350 but provides detailed DIY instructions for experienced homeowners. The quick-connect filter replacement system allows filter changes without any tools in under 5 minutes.
