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 etrailer.com. 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.

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.

It replaced an intermittently malfunctioning (and noisy) unit that came with the 5th wheel. Easy to install, worked the first time - lit stove top and oven on one try - even off from single tank with low gas level.

This item was proposed as a more effective alternative when one tank goes dry the other is auto. Also has gauge to read fill. Really appreciate how the packaging of all the purched products reduced the plastic to throw. Shipping took the time to anchor in the products with heavy card board and staples. Shipping time was very reasonable for meetg thier free shipping threshold. Desciptions and website works well in proposing other alternatives and "ordered together" options. Bravo. Definantly will use again.

  • Hoses and Regulators Needed to Add Dual Tank Propane Setup to Trailer
    I attached a picture that shows what the typical dual tank setup looks like with the accessories needed labeled. First thing you need is pig tails to go from the tanks to the regulator like the part # 100473-12. Then for a dual tank regulator with automatic changeover we have the part # 37207-30395 that each of the pigtails would connect to. Then for a 12 foot long extension hose that would plug into outlet of the regulator you'd want the part # 100040-144-MBS. From there you'd connect...

    Regulators normally have 1/4 inch not 3/8 inch connections as does the small appliance.

If you have 3/8 inch connections, the only option we have for your specific fit is to use multiple hoses.

  • Can JR Products Automatic LP Gas Regulator # 37207-30395 Be Used with Two 100 Pound Tanks
    Yes, as long as your two 100 pound propane tanks feature 1/4" inverted flare fittings (which is standard), the JR Products Automatic Changeover LP Gas Regulator # 37207-30395 will work perfectly. This is a really nice regulator that feature an easy-to-read indicator so you know when the tank needs to be replaced/filled. I have attached a short video review that you can check out as well.

  • Connecting Two Propane Tanks with POL Fittings to Generator
    Since you have propane tanks that have POL fittings you'd want pigtails part # 100019-36 to go from each of them to a changeover like the part # 37207-30395 which is also a regulator. I am not sure what fitting your generator uses but you could then use a feed hose like the part # 100304-12-MBS to connect to it from the regulator if the generator has a female quick disconnect fitting.

  • Dual Propane Regulator is Making Whining-Type Noise
    A bad regulator can indeed be the cause of the whining noise you are hearing on a regulator such as the Automatic Changeover RV LP Gas Regulator # 37207-30395, but there are other causes as well which may come into play. Sometimes, colder weather can induce the type of whining noises you are hearing, as can an overfilled tank, which might explain why this only happens when your regulator switches from one tank to the other.

    Altitude won't have any affect on your JR Products Automatic Changeover propane regulator # 37207-30395 ; even with changes in altitude the regulator will keep the flow the same. If you're experiencing an issue with your propane when traveling in the mountains, it could be because the combustible mixture (propane + air) becomes very rich (too much propane to air) at altitude, since the air is thinner than at sea level.

  • Regulator for Dual Tank Setup on 2011 Heartland Grand Canyon
    For a changeover style regulator for two tanks right next to each other the part # 37207-30395 that you referenced is a great replacement solution. For a single regulator you'd want the part # 108220 and you'd be set. That said you don't need to regulate propane twice so if you have the one regulator installed that gets the feed from both bottles you wouldn't need an additional regulator.
