How Does a Propane Tank Work?

To understand why propane tank valves get stuck, it helps to first learn how a propane tank functions. A propane tank is a storage vessel designed to hold liquefied petroleum gas, commonly known as propane. The tank is constructed of steel or aluminum and holds propane in liquid form under pressure.

As propane is drawn from the tank, the liquid propane vaporizes into a gas that can then be used to power appliances. The pressure inside the tank depends on the temperature, but is typically around 100 to 200 psi.

Key components of a propane tank include:

Tank – Holds the liquid propane fuel supply. Available in sizes from 1 lb up to 1,000 gallons.
Valves – Control the flow of propane in and out of the tank. Different types of valves include:
Service valve – Main on/off valve to shut off gas flow
Relief valve – Safety mechanism that releases excess pressure
Fill valve – Where propane is pumped into the tank
Regulator – Reduces high pressure propane vapor to usable levels for appliances
Gauge – Shows the level of propane remaining in the tank
Collar – Protective metal ring around tank valves

Understanding how these components work together is useful when troubleshooting issues like a stuck valve.

Why Your Propane Tank Valve Might Be Stuck

There are several common reasons why a propane tank valve may become stuck and not turn on/off properly:

Rust or debris buildup – Exposure to moisture or dirt can cause rust and debris to accumulate on the valve stem, preventing smooth operation.
Damage or wear – Internal valve components can become worn or damaged over time, leading to sticking.
Over-tightening – Connections screwed on too tightly to the tank can misalign or bind the valve stem.
Freezing temperatures – Valves can freeze up and become stuck in cold weather conditions. The drop in temperature causes condensation inside the tank to freeze on the valve.
Old age – Valves on older tanks that have seen a lot of use are more prone to sticking issues.

Identifying the potential cause will help determine the best method for unsticking your particular stuck propane tank valve.

The Different Types of Valves Used in Propane Tanks

There are several different types of valves that may be found on propane tanks:

Service valve – The main on/off valve, enables gas flow when open. Usually the handwheel you turn to start and stop propane flow.
Relief valve – Safety mechanism that releases pressure if it builds up too high in the tank. Can be internal or external.
Fill valve – Where propane is pumped into the tank, has a one-way check valve.
Fixed liquid level gauge – Indicates when tank is 80-85% full during filling.
Withdrawal valve – Allows trained professionals to drain liquid propane from the tank.
Vapor equalizing valve – Returns excess propane to delivery truck during filling.

The most common valves are the service valve and relief valve. Knowing the type of valve that is stuck will help determine the proper course of action.

How to Unsticking a Propane Tank Valve Safely

When working on a stuck propane tank valve, safety should always be the top priority. Propane is highly flammable, so take these precautions:

Work outdoors in a well-ventilated area away from ignition sources
Check tank and valve for damage before starting
Have an ABC fire extinguisher on hand
No smoking, sparks, or open flames near the tank
Wear protective gloves and eyewear
Position tank securely on a flat, level surface
Never use excessive force, strike valve, or puncture tank
Stop work if you smell gas and contact propane supplier

With safety at the forefront, here are solutions to try for unsticking a stuck propane tank valve:

Step 1: Check for leaks

Before attempting to unstick the valve, inspect the tank closely for any leaks, dents, rust, or damage. Spray soapy water on the tank and look for bubbles, which indicate escaping propane. If the tank is damaged at all, do not try to open the valve – exchange the tank for a new one instead.

Step 2: Work outdoors

Always work on propane tanks outdoors, away from any ignition sources like flames or sparks. Propane can accumulate in enclosed spaces and pose an explosion hazard. Have a fire extinguisher on hand.

Step 3: Relieve pressure

If the tank contains propane, relieve pressure by opening the bleeder valve on top of the tank. This allows excess propane to escape. Keep the bleeder valve open for 2-3 minutes. Relieving pressure can help loosen a stuck main valve. Please refer to this guide to understand How to Tell How Much Propane Is Left for Your Gas Grill.

Step 4: Lubricate the valve stem

Spray lubricant like WD-40 or silicone spray directly onto the valve stem. Work the lubricant around by gently turning the valve back and forth. Let it penetrate for 5-10 minutes1. The lubricant can help loosen a stuck valve.

Step 5: Tap the valve handle

Use a rubber mallet or hammer wrapped in cloth to gently tap the valve handle in the opening direction1. Apply steady pressure while tapping to help jar it loose. Be very careful not to damage the valve with excessive force.

Step 6: Add weight

If the valve remains stuck, push down on the handle with your body weight while turning it. The added leverage from your body weight can help free a stubborn valve.

Note: Avoid channel locks / wrenches for fear of breaking the valve off which is why manually pressing down on the valve handle to reduce friction may be preferable if it works.

Call for Professional Help

If you cannot get the valve unstuck using these methods, contact your propane supplier for assistance. Technicians have specialized tools and expertise.

With patience and care, you can often get a stuck propane tank valve working again. But if not, experts can determine if replacement is needed.

Another Method: Loosen the bleeder screw

Here is a step-by-step guide on how to unstick a propane tank valve using the video source provided:

Step 1: Check for a bleeder screw on the tank

The first thing to check is if there is a bleeder screw on the tank. This screw allows you to release some pressure that may be causing the valve to stick.

Step 2: Loosen the bleeder screw

If there is a bleeder screw, loosen it to release some gas and pressure. This can be done for 2-3 minutes. Releasing pressure may be enough to unstick the valve.

Step 3: Apply lubricating oil

If loosening the bleeder screw does not work, apply some lubricating oil like WD-40 to the underside of the valve handle. This can help loosen up the valve.

Step 4: Use body weight on the valve handle

If lubrication does not work, the next step is to put your body weight on the valve handle while turning it. Putting your full body weight on it while turning can generate enough force to unstick it.

Step 5: Turn the valve handle slowly

Once unstuck, turn the valve handle slowly. Only turn it a quarter turn each way. Opening it too quickly may cause it to get stuck again.

Step 6: Bleed off excess gas if overfilled

If the tank was overfilled, slowly bleed off the excess gas through the bleeder valve. Make sure all appliances are off when doing this. In summary:

Check for and loosen bleeder screw
Apply lubricating oil
Use body weight on valve handle
Turn valve slowly
Bleed off excess gas if overfilled

Following these steps should allow you to safely unstick a stuck propane tank valve. Let me know if you need any clarification or have additional questions!

Preventing a Propane Tank Valve from Getting Stuck

Replace damaged or worn out tanks and valves

Following propane safety best practices will minimize the chances of having to deal with a stuck valve. But now you’re equipped to handle it safely and effectively if it does happen!

Troubleshooting Your Propane Tank

Beyond stuck valves, there are other potential issues to be aware of with your propane tank:

Valve leaks

If you detect propane leaking from a valve, contact your propane company immediately. Do not attempt to fix leaks yourself.

No gas flow

If appliances are not getting gas, check tank fuel level, connections, and regulator. Reset valves.

Replace the valve

If you cannot get the valve to budge at all, the valve is likely too damaged and will need to be replaced. Take the tank to a certified propane dealer to have the valve properly replaced. Expect to pay $10-$40 depending on tank size.

Get the tank re-certified

Any time the valve on a propane tank is replaced, the tank must be re-certified for safety. The re-certification process checks for leaks and ensures the tank is safe to fill. There is usually a small fee of $10-$20 for re-certification.

Monitoring your propane tank closely and performing regular maintenance allows you to catch issues early before they become big problems. But your propane supplier is always available to provide assistance and ensure your propane system remains safe and reliable.

Safety Precautions

Never try to repair or modify a propane tank valve yourself
Avoid flames, sparks, and sources of ignition when working on tanks
Wear protective gloves and eyewear when handling propane tanks
Work in a clear, open area away from people and buildings
Consider replacing very old or damaged tanks rather than trying to salvage them

Propane Tank Safety Valve Reset

If your propane tank safety valves have tripped, you may need to reset them to resume normal operation:

Store tank in a clean, dry area protected from weather
Locate the main tank service valve and use a wrench to turn fully clockwise until tight
Open propane appliances/valves fully to release pressure
Wait 10-15 minutes for pressure to equalize
Slowly turn tank valve counterclockwise to open and resume gas flow
Monitor flow and close valve when full flow is restored

Resetting the safety valves allows built-up pressure to be released so flow can resume. If valves continue to trip, contact your propane company to inspect for issues.

Potential Hazards of Handling Propane Tanks Incorrectly

While propane is generally safe when proper procedures are followed, mishandling tanks can pose risks:

Fire hazard – Leaks can cause explosions and fire if ignited
Exposure hazard – Inhaling propane or contact with liquid can cause frostbite
Asphyxiation hazard – Propane displaces oxygen in enclosed spaces, causing suffocation
Projectile hazard – Damaged tanks can explode and become dangerous projectiles
Property damage – Flames from a leak can quickly spread and destroy property
Carbon monoxide poisoning – From using propane appliances indoors or in enclosed areas

To avoid these hazards, always follow safety precautions, use equipment properly, and call the experts any time you have a concern with your propane system.

Handling propane tanks seems straightforward – just open the valve and the fuel flows, right? But as you can see, there are many intricacies involved in the safe operation of propane tanks and valves.

Hopefully this guide provides you with a better understanding of propane tank valve function, why they stick, and how to get them unstuck again. Always emphasize safety when working with propane. And remember your propane supplier is there to help anytime an issue arises with your propane tank.

FAQs

1. My Handwheel is Stuck and Won’t Turn On

If your propane tank handwheel is stuck and won’t turn to open the valve, first ensure you are twisting it clockwise to open. The handwheel only turns one direction. Gently tap the handwheel with a rubber mallet while trying to loosen it. Apply penetrating oil or lubricant to the valve stem and let it soak for 5-10 minutes before trying again.

This can help break loose any rust or debris. Over-tightening connections can also cause valves to stick. Avoid using excessive force to turn the handwheel. If still stuck, contact your propane supplier for assistance.

2. My Propane Tank Valve is Open But No Gas Flows Out

If your propane tank valve is open but no gas is flowing out, first confirm the tank contains propane by shaking it and listening for liquid propane sloshing inside. Check that all connections are tight and the valve is fully open.

Valves opened all the way can restrict flow – try opening slowly. Inspect hoses for blockages and confirm appliances are set to use propane. Try resetting tank valves by closing and reopening. If no gas flows, the issue may be with regulators, valves, or connections. Contact your propane company for troubleshooting.
