    In this video, I build myself a simple DIY U Tube style manometer and use it to test out my RVs LP gas system for leaks.

    I actually find and correct one. Not on the RV itself but inside my BBQ grill gas line.

    Disclaimer: Working with LP Gas can be dangerous. I’m not a certified RV technician merely an RV owner. This post and video should not be taken as instructional.

    I’m glad I built this simple manometer and taken the time to learn a bit more about our RVs LP gas system. It will be nice to be able to do a quick test if my wife’s sensitive nose smells rotten eggs or I suspect a propane leak on board the RV.

    Bear in mind though this DIY leak checker should in no way replace having the RV checked out periodically by a Certified RV or LP Gas Technician. (My home province of BC recommends it every two years and it mandatory when reselling an RV) I advise RV owners to research the subject for themselves.

    Love the video Ray, I would make one myself if I didn’t already have a needle guage for natural and lp gas. But what a neat build. I did save the instructions so I can make one down the road if needed. Thanks Again  B-)

    That was pretty cool.  But I wonder if a pressure gage in line with the hose coming from your tanks would not also work.  Then you could just turn off the main tank and if the pressure on the gage drops, you have a leak.  Of course, it would not tell you where the leak is….but it would be an easy way to check every time you set up at a new camp.

    Yeah, you would think with all the safety concerns over propane it would be a standard thing. Maybe if a gauge is left inline it gums up and becomes inaccurate.

    Wondering if having two regulators in series, as with the stove, if the same idea would work in feeding my Buddy heater (Which has its own regulator) off of my house propane. (I’m currently running the heater off of a bbq tank rather than the little 1lb bottles…)

    My assumption was NO, since you, Ray, removed the one on your O-Grill to do essentially the same thing..

     

    Why am I thinking about heat?  See attached, taken 5 minutes ago… Hahaha!!

    Does your Buddy have a low-pressure input port? Mine had two, the high-pressure screw in type and then a low pressure quick connect I plumbed into the low-pressure RV line.

    No, I have the smaller-single burner Buddy. My guess is that there wouldn’t be enough pressure on the diaphragm of the second regulator to let the gas through.

    Yes, I’d say the little Buddy only works straight off the cylinders.
