They GasStop installation for an RV with 2 tanks shows use of 2 GasStops. This is high expense when the regulator has gas going out to the RV with only one line. Explain why the GasStop cannot be put on the hose going to the RV? One reason is the connection is not a good one to get to the propane line in an RV, my case, a copper type L 5/8 in OD pipe. Please address this. I have the GasStop for Travel Trailer RV and am located in the USA, Illinois.
Greetings! GasStops have been designed to protect the entire RV propane system in case of major leaks, to include all the high AND low pressure components (high/low pressure hoses, regulators, connections, etc). In order to do protect all these components, the GasStops must be installed directly onto the tank service valves, so that all those components are downstream of the GasStop (safety first).
With this in mind, the GasStop technology that enables the auto shut off feature is designed for, and can only reliably work in, the high pressure side environment side that these service valves are on (as you know, anything downstream of the regulator is the ‘low pressure’ side). In keeping with this complete safety approach, the only GasStop connections available are those that connect to the service valve types such as POL for class A/C, and ACME type for trailers, 5th Wheels.
