What this site provides
This site is a free sizing worksheet. It estimates the working capacity a salt-regenerated household water softener needs, a regeneration interval, and five-year salt and regeneration-water costs, from your own inputs.
Estimates only
All results are estimates for planning, not a plumbing or engineering recommendation. Household water use varies, and the model assumes steady demand and no price, maintenance or equipment changes. Verify sizing with the manufacturer's specifications or a professional before buying or installing equipment. Dollar prices are your own entries; the site supplies no live rates.
No warranty
The site is provided "as is" and "as available", without warranty of any kind, express or implied, including accuracy, completeness, reliability or fitness for a particular purpose.
Limitation of liability
To the fullest extent permitted by law, we are not liable for any loss or damage arising from your use of this site, including decisions made using its estimates.
No affiliation
This site is not affiliated with, endorsed by, or connected to any manufacturer, dealer or water utility. It holds no product listings, live rates or purchasing.
Third-party content and advertising
The site may link to other websites and may show ads from third parties. We are not responsible for their content or practices.
