We RVers love our propane. That tank of LPG (liquified Petroleum Gas) that is attached to the front of our trailer or installed under our motorhome provides the energy to cook our meals, heat our water, cool our refrigerator, and fire our furnace. Life on the road wouldn’t be the same without it. But propane can be dangerous too. So, we have a propane detector inside to check for leaks and we replace it every five years as required to be sure that we are able to be notified of a problem. But what about those other, unexpected mishaps that can put us in danger. An accident or chewing rodent can sever the rubber hose that connects our tank to the inside propane plumbing and our appliances. If that were to happen, most modern tanks would stop 80% of the leakage. But that other 20% is enough to explode and burn down the RV within minutes. That’s where the GasStop takes over. Installed between the tank’s output valve and the rest of our system, the GasStop will immediately halt ALL propane from escaping into the air. The GasStop is both low cost and easy to install. A careful camper who reads the clear instructions can do it alone. No need for professional installation. Once a severe leakage triggers the GasStop and it works to save our life and property we say a silent “Thank You” to the inventor and head to our favorite RV shop to repair the damage. Once fixed, we just push down on the dial of the GasStop four times to reset it to allow the propane to flow freely again.

Ok, so now we have the GasStop protecting us from severe leakage and destruction. But what about a small, slow leak? Well, the GasStop isn’t designed to shut off the flow for slow, less catastrophic leaks. But it can detect them and inform you when you have a small amount of propane escaping anywhere throughout your entire system. Before GasStop these small leaks could only be detected by certified professionals using specialized equipment. Here’s how it works. First shut off the main valve at your tank and notice the location of the pointer on the GasStop that tells you the amount of propane remaining in the tank. Wait a few minutes and look again at the GasStop dial. If the needle has moved down to a lower reading it indicates that gas is leaking somewhere in your system. The time it takes for the needle to reach empty indicates the degree of leakage. A fast drop, say within ten minutes means that you need to get this resolved at once. A slower drop means it is a smaller leak. Now, no matter if its fast or slow shut off the main valve on the tank and open windows to air out the RV. It’s best to let the professionals take it from here to find and fix the leak. Any propane leak is unacceptable and is asking for serious trouble.

Now that you have the facts about Gas Stop let me assure you that it works as advertised. I installed one on my motorhome and purposely disconnected the regulator to cause a large leak. Wham… the GasStop snapped into action and stopped the propane in less than a second. Next, I tried the small leak test and to my surprise, I had one. Being a bit handy and very careful around propane, I did a little of my own checking. After turning off the main tank valve I removed the GasStop, pointed my phone camera into the tank valve opening and took a photo. The image showed a small black foreign object caught in the threads of the valve opening. It turned out to be a piece of rubber gasket left behind when I had replaced my regulator a few weeks back. So, I removed it and cleaned the area with some alcohol on a cotton swab. After reconnecting the Gas Stop, I tried the slow leak test again. This time the needle stayed put. It never moved. Now I have the peace of mind that not only am I protected from severe leakage events, but also that my entire propane system is tight and leak free. So, for my advice I refer you to the heading. Buy it… It could save your life. In fact, I love it so much that I got one of the other GasStop models for my 20 pound tank that feeds my outside grill.

Our entire family has installed these safety shutoff valves on our RVs about 2 years ago, after having a nearby RV burn to the ground after a fire burned through a rubber gas hose to the RV fridge. The fire was brought under control by nearby campers (the fire dept. had already been called), but when the gas hose burned through, the LP gas valve on the LP gas bottle allowed the gas to keep flowing, although at reduced pressure. The campers were unable to extinguish the resulting healthy, pressure-fed fire These valves are durable and work great. I broke one of the brass valves by accidentally putting way too much side pressure on the brass valve. My bad, not the valve's fault.

I had a propane gauge and it failed recently. Started smelling leaking propane out of it when it failed ! So I bought this as an upgrade. I still get the gauge but now realize how frightening a leaking propane tank is.

Pricey. But time will tell if it doesn't fail like the other .

Easy to install

Wondering if lasts with all of the propane disconnections I will have

You can use on an Airstream, but you will likely need to also purchase the GasStop 90-degree Braided Steel Propane Hoses.

Buyer beware. Before you purchase this item know that you cannot return it for some ridiculous reason. Apparently, transportation of the product is subject to hazardous materials regulation. Amazon shipped it without issue in the same box with other products, yet I cannot return it. Amazon needs to update their return policy for this item because it is simply a valve, nothing hazardous.

Quality product that was easy to install and use. Accurately identities propane level in RV without having to remove tank. Great safety feature in that it can detect leaks and turn off gas.

GasStop doesn't StopGas!

Not recommended!

Amazing very easy to use and install definitely recommend especially for rv use

I have had mine for 4+ years, they have worked great. I have started to have a strange gas cutoff issue starting since it got colder out and contacted GasStop customer support and heard back from them (Matthew) in under an hour (WOW), was provided steps to test my issues and seemed to have found user error was the cause. Impressive customer service and response time. The peace of mind in having these is the reason to keep them. Thank you Matt/GasStop

Arrived before the date it was supposed to according to the shipping info installed pretty easy. Haven't had a leak to confirm that it actually does shut off as supposed to but feel better that it is on in case anything does happen

Good indicator for propane levels on my 30 lb. Tanks.

Got new RV fridge and got this item beginning 2021 and for 4 summers we have been struggling off grid to keeping fridge in safe levels (Lost a lot of milk). Finally at our wits end we removed it 2024 Oct and rv fridge on propane is working beautifully.

As advertised and easy to install.

Quality product, but "detects" a leak when I use my oven and shuts off the gas supply. I have to disconnect before I use my oven, so it is a bit of a pain.

I did however buy it to run my fridge on propane when driving, so it does what I originally intended it for.
