Is it difficult to install by myself?

The system comes with standard-sized connections, a detailed manual, and video tutorials. Many users can complete installation on their own, but a plumber’s assistance can make the process even easier and quicker.

Is there anything special I should know when installing this system?

For best results, apply plumber’s tape and tighten the fittings evenly during installation. This ensures a secure setup and helps prevent seepage, allowing the system to perform reliably.

How long does the housing usually last?

Made with high-strength materials, the housing is built for long-term use under normal water pressure. Adding a pressure regulator can further extend its service life.

Can I install this system outdoors?

Install indoors in a well-ventilated area, shielded from wind and rain, and away from direct sunlight and heat. For outdoor installation, ensure insulation against frost and sun, and waterproofing for both the unit and the pipes.

Does this system remove TDS?

The System is designed to reduce sediment, chlorine, and certain chemicals, effectively improving water quality and taste. It does not reduce TDS. If lowering TDS is your goal, we recommend pairing it with an iSpring RO system.
