Frequently Asked Questions
Do salt-free water conditioners really work?
Yes, salt-free conditioners using TAC technology are proven to prevent 99.6% of scale formation. They don't remove minerals like softeners do, but they prevent those minerals from forming scale in your plumbing and appliances.
How long does TAC media last?
Quality TAC media typically lasts 6-10 years depending on water hardness and usage. Media replacement is the only significant maintenance required.
What size system do I need?
Choose based on your home's peak water demand (simultaneous water use). As a rule of thumb: 1-3 bathrooms need 7 GPM, 4-5 bathrooms need 10 GPM, and 6+ bathrooms need 12 GPM.
Can I install it myself?
Most systems are DIY-friendly if you have basic plumbing skills. However, some manufacturers require professional installation to maintain warranty coverage. Check warranty terms before proceeding.
