Video Transcript for JR Products Compact Low Pressure 2-Stage Automatic Changeover RV LP Gas Regulator Review

What's up everybody It's AJ with Today we're going to be checking out this automatic changeover regulator from JR Products. What this is going to do is it's going to help you, obviously, regulate the propane in your rig, but it's automatically going to switch over when one tanks down. So right now, the lever's pointed to this tank. When this one reaches its end, it's automatically going to switch over to this one. That way when you come back out here next time, you'll switch a lever over to primarily focus on this one and you can replace this one without worrying about any gas escaping or anything like that but continue to have propane.

Let's check it out.A way it helps you figure out which tank is empty is this gauge here. I'm going to open up this propane and you'll see the gauge will turn to green. Now you know that this one has propane it. So it sensing that it has propane. It's going to be fine.

There's no reason to change the readout. Now, if I flip it over to this one, you're going to watch it slowly switch over and realize there's no propane in this one because I have the valve shut off. With that in mind, just because it's red doesn't mean both tanks are drained. You'll want to switch it over to the other one, you see green and knows this one's full and you're still good to go and you can replace this one now.Now, we worked with two different regulators today. Both of these are from JR Products, but the only difference is this one's a little bit bigger and has extra screw holes.

Otherwise, it's the same thing. Functions the exact same way. You just want to go with the bigger one if you have more appliances that are drawing propane off of it. So like I said, you got way more stuff running off it, you're going to need a bigger regulator to regulate the propane. It's going to help you out with both of your tanks just the same.

Chances are if you're checking this out, it's time to replace your old one. Here's the old one here. We went ahead and removed that, and you needed to do that every 10 years. They recommend it because it's got a rubber diaphragm on the inside that eventually wears out, then you're going to get less pressure. Now, that goes the same with your propane tanks. So if you do them at the same time, that'll work out. If you don't replace your propane tanks and you just get them refilled, up to 10 years it's time to get them reinspected to make sure they're still okay to use. You'll have to take them to a propane place to get them inspected and approved to use.Another thing to think about when you're going to replace your regulator is the hoses that go with it. You want to make sure you get the right ones that have the right connections. We have the inverted connector here. You can see it's smaller than the outside grip, and then we have the NPT connection and you can see that that threaded part matches the outside grip. So that's an easier way to tell just by looking at it and going, "Oh, okay. The bigger one that comes all the way out to the end, that's the NPT, and this is going to be the inverted." If you look at our regulator, it uses the inverted. So you can just come in here and screw it in that way. If we we're going to try and use the NPT, clearly too big. It's not going to thread in there. Looking at the outlet down here, this is going to be sized at 3/8" and it has an FPT connection. So another thing about when going with the lines you're going to be running to it, make sure that matches up with the one that goes to your rig.It's pretty straight forward. That's how the regular works and how you would replace it. But how does it install It was pretty easy. So let's check out how we did it. This is what it's going to look like when you get it. Now, we added a bracket to our regulator that JR Products also offers that's on our website, because the old bracket wouldn't work with our new regulator. It didn't had four screws in it, and the screw spacings didn't match up with this one. This one's an inch apart. So that's something else to look at when you're going to get your replacement. Make sure the bracket matches so you can attach it, that way you can attach it over there too.So first off, I put one screw in there already. Going to simply put the second one in. That way we attach the regulator to the bracket. I'll show you the back of the regulator here in a second. You can see it's got the spaces there where the screws go in. So it's as easy as lining the bracket up and screwing it in. We're going to attach our output hose to the bottom here, the regulator. It's easier to do that before you install the regulator because you can easily just spin it like that and attach that bottom hose. Get it nice and tight. Looks good. Now you can go ahead and set the bracket down on top, because there is a hole just for it and then we'll add our wing nut to hold it in place. Again, want to get it nice and tight. Just going to push down on this bracket and this bracket keeping everything in place.Now we're going to add our other hose. It's easier to screw in this side, which would be our inverted side first, and then attach this side to the propane tank. You're all set. It really is that simple. It installed very easily. It works great. I like that I can switch over to this tank if I need to, but I don't have to. If this tank runs out, it's automatically going to come over here while I'm inside. I don't have to leave the camper if it's cold. I really like that. It makes it easier, and I know I'm covered for the next 10 years. That does it for our look at this regulator. Hope this helped.

Automatic changeover regulator eliminates interruptions by automatically redirecting LP gas vapor flow from an empty cylinder to a full cylinder. Regulator features an indicator that changes from green to red when cylinder needs to be filled.


my old vavle would only let my refrigerator and stove work in rv camper and not the furnace, just hooked up and now my furnace works. I think I will like the automatic tank change over where I did it manually on old vavle.


Couldn’t get it to work. Didn’t fit. Terrible customer service. After I returned it, turns out all I needed were some self tapping screws that should have been included.


Purchased as a replacement for the recalled LP regulator on my travel trailer. Easy to install and works perfectly!


This item took a little while to receive from being on back order which was not a problem, installed it hooked up the propane bottles and verified operation all good. Thanks, etrailer for the excellent products. Always happy to do business with your online sales.


Easy replacement changeover regulator and still works great


I'm rating this as t stars for the follow through bt this was definitely held up due to supply chain issues for quite some time. etrailer followed up monthly and kept me in the know as they worked to frequently communicate with the supplier. Good outfit to do business wise.


Our orginal equipment broke and led to several cold evenings. This regulator works great and was easy to install.


Thank you etrailer. On vacation I needed the ordered part shipped to the RV Park we were staying at. I paid extra shipping for faster delivery. Part was promised for Monday, I received part the Saturday before scheduled delivery. Wow, did I luck out. Thank you sales person Kimberly R. Shipping label was correctly addressed to RV Park in care of me, just as she promised me. Thanks so mush.


George J. Kept me updated on my order as the item was out of stock. Once they received it they shipped it out. Every time I’ve ordered form etrailer service has been outstanding


Fit like the regulator was made for the trailer. I own a reflect 303rls.
The regulator slowed down the vibrating noise when using propane that I use to have.


Has worked out great. Have been living in my trailer in my trailer for nearly a year while building a house. The regulator replace another one which died prematurely and I use it everyday.


perfect replacement for recalled regula tor


Received unit in Good Condition. Took away one star because the regulator required calibration on receipt. It was supplying 15.5" WC pressure instead of 11". Was easy to adjust but a specialty tool is required. Etrailer did a great job keeping me updated on order status.


After a very long wait, which was of no fault of etrailer, the Regulator finally arrived. I installed it and it works perfect. It was exactly what I needed. The Regulator industry is apparently very far behind, which is why it took several months to get the item.


Works perfect as replacement for recalled part.


I tried to get this regulator through a dealer under warranty and was told they wouldn't be able to get it until May. When I ordered it through you,I was told around the first or April. I received it March 8th. Thank you very much for the quick turn around.


It works well and it's very nice not having to worry about switching tanks out in the rain or in the snow or any inclement weather.


Quit working properly after 6 months - shaky flames indicating a regulator issue. The red-green indicator only worked for the first three months. I replaced it with a different brand.


Looks great. Haven’t installed yet but everything I have ordered in the past from e-trailer has been great.


Came quickly after the order and works great.rxactly as ordered.


Thank you etrailer for great service. Both the faucet and the LP regulator were installed within 2 hours of being delivered. They are both working better than expected we are looking forward to our upcoming trip. Thanks again.


Worked perfectly right out of the box.


The same as the one I removed. Work gre at.


Awesome upgrade to my old setup!


Love your product.
