Will 2-Stage Automatic Changeover Propane Regulator Emit Propane Smell

Updated 01/15/2021 | Published 01/13/2021

Question:

I believe I have this same automatic cross over regulator between two propane tanks. With the travel trailer only being just under 2 years old I wouldn't think the regulator would have gone bad already. I know it has a vent on the center bottom and mine even has a plastic cover over that section but I do smell a slight amount of propane when I open the large exterior plastic cover lid so is it normal to have some dissipate from the vent? I closed the tanks off and checked all connections that seem tight so Im thinking I might be on the safe side and order a new one if that vent doesn't usually let off any odor but with it being a vent I figured I would inquire first. I did notice the dust cover wasn't screwed in all the way too but that just looks like it covers an adjustment screw?

I'm glad you asked, because there should not be an odor of propane coming from anywhere, including the vent, of your automatic changeover propane regulator.

You are correct that a regulator should absolutely last longer than just a couple years (most are meant to be replaced approximately 15 years) but on occasion they do go bad, which is what happened with yours and why it is emitting the odor of gas.

So you will definitely want to replace yours with the Compact Low Pressure 2-Stage Automatic Changeover RV LP Gas Regulator # 37207-31525.
