    5.0 out of 5 stars Great item, make sure the vent is in the right orientation

    Happy with the quality of the brand. Just make sure you order one with the right orientation for the vent.This model has the vent pointing toward the inlet. I needed one that the vent points toward the outlet (the gas line on my setup runs down into the ground from the tank). Had to return this one, but thankfully Emerson-Fisher makes this same version with the vent pointing down (toward the outlet) with model number R622-DFFXB.

    5.0 out of 5 stars fixed the problem
