The RED regulators are a HI to lower pressure regulator that is a safety device. They decided to run the LP to the other standard regulator and NOT use the HI pressure thru the line to the other side. So, they use that RED regulator to drop the hi pressure to a safer low pressure before it connects to the other switchover regulator assbly. The USUAL cause of a regulator leaking is the tanks were overfilled and the liquid entered the regulator and the freezing liquid destroys the diaphragm. Overfilling is caused by NOT using weight when filling and using the 80% valve to signal full which is WRONG and allows overfilling and this is what happens. Doug
My LP tank has been filled to 100% three times, it is old, has no OPD and is not required to have one due to being a horozontal MH DOT tank.
I now stand at the switch and turn off the pump for the LP distributor, where I live they all depend on the OPD to cut off the flow, we know that is wrong just like Dougs example. But that is how it is.
When the liquid propane went through my regulator and an Extenda A Stay fitting, through an LP hose to my smoker burner the flames were ten feet high.
Imagine if the unsuspecting river were to light the stove top!!
I was intentionally trying to burn off the excess LP with my smoker burner because I knew it was overfilled. The flames were so intense I turned off the LP tank valve, un hooked the hose and the liquid propane in the 12 foot hose burned for another ten minutes.
I think some RV fires are caused by overfilling LP tanks. Just my thoughts.
