Field Topics are intended to provide useful information to the network of authorized LP-Gas and Anhydrous Ammonia distributors regarding the proper use of RegO® products. Warning Bulletins covering many of the hazards involved are available from RegO for more detailed information. These bulletins can be found in our L-500, and NH3-102 catalogs. Neither the Field Topic or the Warning Bulletins are intended to conflict with federal, state, or local ordinances and/or regulations, which should be observed at all times. This information also is not intended to be a substitute for or to supplement any training in the safe handling and use of propane and related equipment, as required by any applicable law. By providing this material, ECI assumes no responsibility for providing any such training. Only individuals properly trained in the safe handling and use of propane and related equipment should be permitted to do so, and by providing this information, ECI does not assume responsibility for providing such training.

Submerged Regulators

This field topic is designed to help aid in the installation of regulators. Specifically, it guides users on how to avoid placement of regulators where they can be submerged underwater. If a regulator has been submerged in water—replace the regulator. Water from floods can carry many chemicals that can attack the components including the diaphragm, seat disc, and lever assembly.

Proper Placement of Regulators

The regulator is often considered the heart of an LP-Gas installation and proper placement is vital in order to maintain steady flow of LP-Gas to consuming appliances. The regulator should be placed to avoid any condition where the regulator could be submerged under water.
