Terms of use

This site offers general troubleshooting information for homeowners. It is not a substitute for a licensed plumber, HVAC technician or electrician, and it is not advice about your specific home, which we have never seen.

You are responsible for deciding whether a step is safe for you to do, and for following your local codes and your equipment's manual. Where a page says to stop and call a professional, or to leave the house and call 911 or your utility, do that.

We take care to source every statement, and the sources are listed on each page, but we cannot guarantee that the information is complete, current or right for your equipment. Manufacturers change parts and procedures. Check your model before buying or installing a part.

Brand and product names belong to their owners and are used only to identify compatible parts and to cite their published guidance. Vent, Valve & Volt is not affiliated with or endorsed by any manufacturer named on this site.

Product links on plumbing pages go to FourHome listings on Amazon. FourHome is our own brand. Purchases are governed by Amazon's terms.

The content of this site is ours and may be quoted with a link back. Do not republish whole pages. Diagrams and photographs may not be reused without permission.

We may change these terms by posting a new version here.
