The problem that exists in the RV Propane systems is that if there is a leak, there is no device that can 100% shut off the propane going into your RV.
Let’s take a look at the current technology to assist with propane leaks in a RV. The valve at the propane tank, called an overflow protection device (OPD valve), can be turned on and nothing with come out of it, as long as nothing is attached to the valve. Some of you may remember many years ago, before 1998, this valve did not have any mechanism to control flow once it was turned on. You could turn the valve on, and propane would freely flow. With the new OPD valve, if you turn on the propane tank, nothing will come out, unless you attach a propane hose to the OPD valve. This is a great safety measure and it works great. The problem exists when you attach the RV propane regulator to the OPD valve. Now when you turn the propane tank on at the OPD valve, the safety mechanism in the OPD valve is useless. The safety mechanism at this point transfers to the regulator that you just attached to the OPD valve. The regulator has an excess flow valve that will slow down a leak, but has no feature to stop a leak. The excess flow valve essentially is a spring-loaded cylinder in the regulator that acts only if the flow is over 200,000 CFM. If the flow is over 200,000 CFM then it is basically stopping anything in excess of this. Of course, anything less than this still flows and can quickly fill the RV up if there is a leak.
The product to 100% stop a gas leak is called GasStop. This is a high quality unit that attached between the OPD valve and the RV regulator. With this unit, if the flow is above 75,000 cfm, which is regular operating flow, then the unit will 100% stop flow. So this unit will of course not affect regular use, but if a leak starts in the system, it will identify that and completely shut off the flow to your RV. Every single RV in America should have this unit, and they are not expensive to get, and now you can get it at TechnoRV.
So where can leaks occur? A leak can happen anywhere you have propane running too, like the stove, water heater, refrigerators and heaters. Then, there are the connection points that can leak, and finally the issue of a propane line being damaged. You could have a rodent chew through a line, or a tire blow out that cuts a line, or even the line just rubbing up against a object while traveling. Of course, if you are traveling then you should shut your propane off, but statistics show that the majority of RVers do not turn off their propane, or at least forget on occasion. The reasons for leaks are really irrelevant, the fact is that propane leaks do happen to RVers, and more often than you may think. The GasStop device stops the leak instantly!
There are two different GasStop styles because there are two different types of propane tanks that you will see in a RV. For the Class A and Class C units, you will need the POL style GasStop connection, and the towables will have the standard acme style propane connections. Installation is as easy as screwing the GasStop device onto your propane tank, then attaching your RV propane line to the GasStop device. Once you have the unit physically attached then you simply prime the GasStop Device and you are ready to go.
Another great feature of the GasStop device is that you can use it to check for leaks in your RV. Just put the unit on and charge the system, making sure all of the propane devices are turned off in the RV, let it set for about 5 minutes. If the GasStop gauge does not move, then there is no leak at that time. Checking for propane leaks used to involve special tools and a lot more time, and with this device it can be done quickly.
Remember, if you have two propane tanks, then you will need to get two GasStop devices. We love bringing you the latest in technology and design, and when we saw this unit we knew we had to start selling it. After testing the unit a hundred or so times, and feeling the quality in the unit, we loaded them up in our warehouse and are presenting them to our newsletter list first. Eventually every RV in America will have these units on them because it is a necessity in the RV market.
