Terms of Use

Using this site

You may read, print and share links to these pages for personal, non-commercial use. Please do not copy whole pages, photos or infographics to another website or publication. The guide may change, move or remove pages at any time, and links to other websites are provided for reference only; this site does not control their content.

Information, not professional advice

The guides summarize what water suppliers, government agencies, building codes and manufacturers publish. They are general information, not plumbing, engineering, medical, legal, tax or insurance advice, and they cannot account for the details of a particular house, well or septic system. For a decision that matters, check the original source linked on the page and ask a qualified person: a licensed contractor, a certified laboratory, your water supplier, your county environmental health office or your insurer. If your supplier issues a notice about your water, follow the supplier's notice.

Safety

Some guides describe work around gas, electricity, hot water and pressure, such as flushing a water heater or shutting off a main valve. Follow the manufacturer's instructions for your equipment, turn off power or gas before working on an appliance, and stop and get a licensed professional if anything is unclear. If you smell gas, leave the building and contact your gas company or 911 from outside. California requires a licensed contractor for many jobs, as the hiring guide explains.

Prices

Any price shown is the figure a named source published on the date given, such as a store's listed price or an agency's estimate. Prices change, and a quote for your own home can differ widely. Store prices belong to SoftPro Water Systems, which shares this site's owners as set out in the ownership disclosure; its own terms govern any purchase.

Changes

These terms may be updated as the site changes; the date below shows the latest version. The site is provided as is, and to the extent the law allows, its owners are not liable for losses arising from use of the information. See also the privacy policy and the accessibility statement.
