Re: Electrical propane shut off valve
Now you mention it, all I could find in the ABYC code is that the regulator must include a way of isolating one cylinder from the other - you can't just t them before the gauge - which that regulator includes. Guess the design then necessitates two gauges to be able to leak check it whichever channel is selected.
Why don't they put the gauge after the valve and thus save a guage? Who knows? So you can see if both tanks have gas in with just one selected?
The handy thing with 2 gauges is that if they both drop, you know the leak is downstream, whereas if one drops, the leak is between the gauge and the tank.
