Simple troubleshooting... When working with Armstrong Fluid Technology bearing assemblies, couplings and pumps we need to ensure all is intact. It's something that can be overlooked on a call or pm. Techs can get confused due the motor running, a quick inspection or amp draw will tell you that the pump is not doing any work if the coupling breaks. #hvac #hvaclife #hvacsystem #hvactroubleshooting #pumptroubleshooting #hydronics #hydronicheating #hvactraining #plumbing #boilerpump #boilercirculato
