You often see many of our articles and social media posts and YouTube videos note the use of a Fireman's Friend valve on tankers. The problem is that the photos and videos we show never show the actual valve/device since it is located inside the tank. While sorting through some photos we shot from a couple years ago we found a few photos that we took of a 4-inch Fireman's Friend that was not yet installed. We thought we would share them with you in case you never saw the actual device. Note - the photos on the uninstalled valve and the installed valve are not from the same area of the country.
