I had to replace an old regulator on our camper. I decided to get this one. It was an easy installation. It worked great. I highly recommend this regulator.

Bought this Flame King automatic changeover valve already year ago and during that time I've only changed my tanks twice, so I was distressed when I had no propane at my stove last night, as that tank had been on only one week. I went out to make sure the tank wasn't defective and found one of the hose fittings leaking propane. This morning I checked it out and found the hose was leaking at the crimp connection. Ordered new, braided stainless hoses (again from Flame King) but they won't be here for almost a week. Can't say what caused it, but i will have a spare hose from now on.

This Flame King propane regulator is a game changer for my travel trailer. It’s easy to install, and the auto changeover feature works flawlessly. No more worrying about running out of propane unexpectedly. The included pigtails are a nice bonus. Definitely a must-have for anyone with an RV or trailer.

This Flame King 2-stage regulator is a game-changer for my RV! The auto changeover works flawlessly—when the primary propane tank empties, it silently switches to the reserve without interrupting my stove or water heater. The two 12-inch pigtails are perfectly sized, and installation took mere minutes. The regulator’s build quality is impressive, maintaining consistent pressure in both freezing and hot weather. A must-have for any RV owner!

I purchased in Jan 2023 to replace 5 year old valves. In March 2024 the one metal hose came out of the fitting. I was out of work at that time and couldn't replace it so I used just the half that was still working. I came home tonight to a horrid smell. The whole connection had blown off. Thank goodness I didn't have a full tank at the time. I would never purchase this product again. It didn't just leak, it burst.

Works like should. Have not had any issues. Though not a auto switch over, I did not want electrical power to basic devices. I live off grid and harness my own energy. I just use two 20lbs tanks for a stove and on demand propane water heater. Using this device for 2 tanks, over a year of use. I couldn't say for larger 60lbs tanks, but guessing this will work well.
