Buying Guide: Key Purchase Considerations
- Compatibility: Check connection sizes (1/2″, 3/4″ IPS, NPT) and ensure fittings match your existing plumbing and valve kits.
- Maintenance needs: Flushing kits should be compatible with common cleaning agents; verify included or compatible cleaners and the ease of flushing sequences.
- Power and efficiency: Electric POU units save space but require proper electrical capacity (voltage, amperage). Gas-powered or condensing models demand venting considerations and fuel supply.
- Safety certifications: Look for lead-free materials for potable water components and ETL/UL listings for electrical units.
- Space requirements: For tight spaces, prioritize compact POU units or under-sink configurations with minimal footprint.
- Durability and warranty: Favor brass fittings, corrosion-resistant materials, and clear warranty terms for long-term reliability.
- Ease of installation: Kits with clear instructions, pre-assembled hoses, and included adapters reduce installation time and potential leaks.
- Service accessibility: Choose suppliers with broad compatibility across major brands (Rinnai, Noritz, Rheem, etc.) to simplify replacements or upgrades.
