The LP tank has a gauge on it that tells you how much is in the tank. When you go to the fill station you must unscrew a cap in order to fill the tank. That cap must be kept on the tank to keep debris from entering the tank. You will also find a pressure release valve on the tank that is a safety device used when filling the tank. Of course there is also the on/off valve. While traveling, this valve should always be closed. It should only be in the on position when it is in use. The last part of the LP tank is the LP regulator that controls how much is going into the coach at a time.

Once a year you should perform a routine inspection after removing your RV cover. Start by checking for leaks in the LP system. A professional could check the pressure with an instrument called a monometer but why spend the money for that service when you can do it for a fraction of the cost. All you need is a spray water bottle with some very soapy water. Turn on your LP system and then spray around the entire tank and all the connections. If you should see any bubbles ten there is a leak in the connection. Tighten the connections and don’t forget to test the connections to your refrigerator, stove and water heater.
