Who can install a LiquaGen system?
LiquaGen systems can be installed by any homeowner with basic plumbing knowledge. For complex whole-house systems, we recommend using a certified plumber.
How long does installation typically take?
Most under-sink and RO/DI systems install within 45–90 minutes. Whole-house systems may take 2–4 hours depending on plumbing accessibility.
Are there any additional costs during installation?
All essential components are included. However, you may need minor plumbing fittings depending on your home’s existing connections.
What tools are required for installation?
Basic plumbing tools such as an adjustable wrench, Teflon tape, and a drill (for RO faucet installation) are typically needed.
How long do filters last after installation?
Filter life varies by usage and water quality. Most pre-filters last 6–12 months, while membranes and specialty media last 2–5 years.
