Here is some customers’ reviews about this Hoover SteamVac Dual V Tank Valve.
I was very happy to find this part. It allowed me to fix my leaking tank without having to replace the entire tank.
This Hoover SteamVac Dual V Tank Valve came in a small plastic bag without any installation instructions. We had a hard time getting it to fit on place. It took a lot of force and we we weren't sure we were doing it right, without instructions. In the end, we got it in and it works fine. It is a lot cheaper to replace this valve than to replace the whole tank.
Bought this is December, but couldn't figure out how to put it on. It was time to clean my carpets again, so I once again attempted to force the valve in, even using some of the carpet shampoo to make it easier to push in. That's when the rubber valve came apart from the plastic middle. This Hoover SteamVac Dual V Tank Valve took a minute to realize all I had to do was push in the rubber valve, then push in the plastic middle. It works great! It would have been helpful to have a few instructions.

Air drain valve and A water heater drain valve

An air drain valve allows the removal of potentially harmful condensates such as water, oil or rust. These contaminates can build up over time and can lead to airline obstruction or weakening of the storage tank. Excess water in the air drain valve system could cause the interior of steel storage tanks to rust as w. Automatic air drain valves are commonly used on large trucks with air braking systems to drain oil and water that could potentially cause the brakes to fail. A water heater drain valve is used to periodically drain water and remove contaminates from hot water heaters. Over time, mineral scale consisting of calcium or other minerals can form on the inside of water heaters. Sediments such as dirt or sand can build up in the bottom of the tank as well. This lowers the heating efficiency of the heating elements and can eventually lead to permanent damage if left unchecked. Periodically opening the drain valve can allow most of these contaminates to drain from the hot water heater.
