How we make money

Vent, Valve & Volt is free to use and carries no display ads. It is published by the team behind FourHome, a brand of replacement faucet and shower parts, and it earns money in one way: when a plumbing result identifies a worn part and you buy the FourHome replacement on Amazon through a link on that page.

Those links go to our own product listings, so we are the seller, not an affiliate. If Amazon's attribution program is active on a link, Amazon can tell us the click came from this site. That does not change the price you pay.

We only link a product where the result actually calls for that part. A running toilet, a water heater or an outlet problem has no FourHome part, and those pages carry no product links at all. Heating, cooling and electrical results may one day link products from stores we open for those categories, and the same rule will apply: inline, next to the fix, only when it is the part the fix needs.

Nothing on this site is paid placement. No manufacturer, contractor or brand pays to be mentioned, recommended or left out. When a result says to call a professional, that is our reading of the manufacturer and safety sources listed on the page, and we have no arrangement with anyone who might get that call.

The second thing we collect is an email address, if you choose to give one, to send a printable checklist. We do not sell or share that list.
