If there is propane in the tank there will be pressue. It can't lose its pressure. If one has a propane tank that has "lost its pressure" even though there is propane in the tank, there is almost certainly a problem with the valve (assuming the individual attempting to use the tank knows how). There is an overfill valve inside the tank. It is a component entirely separate from the external valve that a user controls. Let a propane company sort it out. They're the experts, and they want you to come in so they can help. They live for stuff like this because they are professionals.

How much pressure in a 30 lb propane tank?

You cannot use output pressure to tell how full a tank is. The pressure will remain constant until it's just about out of propane. You can use weight, if you know how much it weighs when empty, and when full - then it's just simple math.


Is propane gas liquid or gas?

Propane is a gas a room temperature if it is not compressed. However, if it put in a canister under high enough pressure, it will be a liquid even at room temperature. Propane is a liquid below -44 degrees F or if its compressed. Grill bottles are only fillid 80% full with liquid. so you can use the propane gas on the top of the bottle.


Does cold affect propane?

Yes and no. Propane is very nonreactive by itself (except when burned in oxygen). The temperature that propane is at doesn't effect it's properties. Also, propane has a very low freezing point (-188°C) so it won't freeze when it gets cold. However, when using propane for a stove, etc., cold can affect how well it works. A propane tank is full of liquid propane under pressure. When it is being used, the liquid first has to vaporize to a gas, where it can then be burned. Because it takes a lot of heat for the liquid to vaporize into a gas, cold weather can slow down the flow. If this is a problem, the propane tank can be placed in a bucket of lukewarm water so that heat is available for the propane to vaporize.


How many pounds of propane can a 20lb propane cylinder safely hold?

A 20lb propane cylinder typically holds around 4.7 gallons of propane. Propane weighs about 4.2 pounds per gallon, so a 20lb cylinder can hold roughly 17-18 pounds of propane when full.


Can you leave your propane tank outside in winter?

Yes, as long as you keep it in a secure covered area. However damage from extreme cold can affect the valves controlling the flow of propane from the tank which can cause problems (potentially very dangerous) come time to use it.

What is the psi on a 20 lb propane tank?

The pressure inside a propane tank depends on the ambient temperature of the tank and if Liquid Propane Gas (LPG) is present inside the tank. It has nothing to do with the size of the tank. A 20 lb tank that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG, just as a 200 lb that is not more than 80% full, in an 100 degree F environment, with LPG in it, will have approximately 172 PSIG. Examples are: A tank with LPG (no more than 80% full) at 80 degree F with have 128 PSIG, 60 degree F with have 92 PSIG, 30 degree F with have 51 PSIG, and -20 degree F with have 11 PSIG. This explains the decrease in pressure as you use a large amount of propane from a tank quickly. The tank cools due to the venture effect which drops the temperature of the LPG. The drop in temperature results in a drop in pressure. When the tank warms up, as long as Liquid Propane Gas is still present the pressure will go up.

Why is my full propane tank not working properly?

There could be several reasons why your full propane tank is not working properly. It could be due to a faulty regulator, a leak in the tank or hose, or a problem with the appliance you are trying to use the propane with. It is important to check for any visible damage or leaks, and if you are unsure, it is best to contact a professional for assistance.


How many lbs in a 375 gallons propane tank?

The weight of a 375-gallon propane tank will vary depending on the level of propane it contains. Propane weighs about 4.2 pounds per gallon. Therefore, a full 375-gallon propane tank would weigh approximately 1,575 pounds.


Can you leave your propane tank outside in winter?

Yes, as long as you keep it in a secure covered area. However damage from extreme cold can affect the valves controlling the flow of propane from the tank which can cause problems (potentially very dangerous) come time to use it.
