Definitely an upgrade to my stock regulator who after 3 years already had rust on connectors. Easy to install, looks great, and ease of use/ simple design.

Great product that worked as shown. Product fit no problem but I did have to replace the mounting bracket with my old one which was easy to do. The old one had the L bend on both ends with holes so it secured the top and bottom of the regulator to the threaded rod that holds the tanks. This one came only one L bend so it would have moved around if I didn’t use the old one. Other than that it was a good purchase.

Broke in under a year. It Broke all on its own was running fine then poof, got the dsi light and went out. Found one side, cheap plastic connection broke to bottle 1 broke and leaked out till empty, and instead of switching tanks the regulator blows the gas out thru the crack from tank 2. Which means the internal bladder broke too. Waste of $ ugj

I now have installed the second one of these, as the first arrived malfunctioning and with one valve cracked. The second one works. It was easy to install. The tank changeover indicator is supposed to be clear when there is propane in both tanks, and then switch to red when the first tank has emptied. While the red of empty seems pretty obvious now, the clear color never was really clear. It was clear with red streaks, or with partial red even with full tanks. So, until I had played with it a while, I wasn’t clear what that meant. Ultimately, if the indicator is fully red, the first tank is empty. I’m convinced that anything else means you still have gas in the indicated tank, and that you can’t use “a little red” to suggest that your tank is running lower pressures. The other thing to know is that you must open the valves on the tanks slowly. Otherwise, the regulator will also show red from too much pressure. I don’t know if it actually turns off that tank, but your indicator won’t show you the true status of the tank. In summary, this works pretty well, but is definitely more nuanced than the one that it replaces. I suspect I’ll adjust to it fine, but it took a while to figure out the interpretation of the indicator.

Having used the RV Automatic Propane Tank Switch Over Regulator during several camping trips, I am thoroughly impressed with its performance, especially in extreme weather conditions.
The regulator’s ability to automatically switch between two propane tanks is its standout feature. This ensures a continuous supply of gas, eliminating the need to manually change tanks, a real convenience during my travels. The indicator, which clearly shows which tank is in use and when it’s time to refill, is a practical addition that I found extremely useful for maintaining a hassle-free propane supply.
Installation was a breeze, and the build quality of the regulator is commendable – it feels sturdy and reliable. Whether it was for heating or cooking, the regulator adapted to different propane demands without any hiccups.
One of the most impressive aspects of this regulator is its performance in bitterly cold weather. Unlike some other models, it operated flawlessly, maintaining a consistent gas flow even in freezing temperatures. This reliability in cold weather is a significant benefit for anyone who loves winter camping or lives in a colder region.
Overall, this automatic switch over regulator is a top-notch accessory for any RV owner. It brings convenience, reliability, and peace of mind, enhancing the overall camping experience. For those looking to simplify their propane management, this regulator is an excellent choice.

Five to ten minutes to install, don’t tork to much the pipes screws, plastic is not very strong. Don’t forget an output adaptor (fitting) and a roll of pink Teflon (you need pink Teflon for propane, never use the white one!!!). The selector is very useful 👌, you can change the empty bottle without having to re-light the pilots for hot water 💧.

This worked great!
Few helpful instructions were available, so I thought I would help others with the answers I came up with. First, you replace existing single regulator that if you are lucky, has the same 3/8” connection that the new dual regulator has. Just might have to make that connection longer to new location, between the two tanks, to the center clamp rod in the tank mounting kit I purchased.
Remove your regulator, likely 3/8 pipe thread, extend the connection to the new location, mount to center all thread rod of your dual tank holder kit with nuts you buy extra with washers and locks. Add nuts to bottom of rod to lock rod in place. Remove bracket from back of valve. (Can’t twist the pipe connections to tighten if mounted in place.) Mount bracket it so it is below the bracket that holds down the two tanks. May have to replace center rod if there isn’t enough threads for that position. Pinch the bracket between nuts on center rod. Installed extra pipe to make up distances. Use gas Teflon tape on Connections.
Used 3/8” galvanized pipe. I actually could not find 3/8” galvanized pipe parts long enough to get to new location between the two tanks, so I used 1/2” pipe for the longer parts and 1/2” to 3/8” adapters. Original regulator was mounted to single tank holder on the left side rear of tank. The optimum position for the dual is to the center rod of the dual tank holder kit. For me that was 12” horizontal and 10” vertical. So I used 3/8” to 1/2” pipe connection, to 10” 1/2” pipe, to 1/2” 90 degree elbo, to 4” 1/2” pipe, to 1/2” to 3/8” pipe adapter, to a 4” 3/8 pipe. Using yellow gas pipe Teflon tape on threads, hooked it up in that order. Started with bracket removed from back of valve. (You end up spinning the valve on the pipe last to make last connection). Purchased extra nuts the same size as the center rod to mount bracket to rod below the clamp height on that rod. Reinstall valve to bracket putting the two screws back into regulator. Test for leaks.
Ok how do you operate it? After testing, the lever points (bottom end of lever) to the primary side in use, giving you the ability to remove the opposite side. But it will supply gas from the secondary side without changing the lever. So for example your right tank is half full and the left side is full, you would point it to the half full so it would finish getting empty. When empty the full side would take over and the indicator would by red. Then when ready to fill the right side move the lever to the left side. You can test how it work easy. Open right tank and point lever to it and then light stove. Turn off tank and stove goes out. Turn off stove. Now open tanks on both sides and light stove, lever still to right, then turn off right tank. The stove will stay lit. But the indicator will go red. If you turn the lever to left the indicator goes black again. The automatic switch over is so quick the stove never faltered. Hope this helps. Yes if you don’t check the indicator you could run out of both tanks. If worried turn valve of secondary off to you run out, then turn on secondary knowing primary is empty.
