Hot Water Circulator:

To circulate the hot water in the system piping, systems use one or more small pumps. These pumps are low maintenance items and are usually installed in pairs, with one operating and one in the backup mode. R and A Plumbing and Heating are high maintenance, they cannot be ignored. Most pump failures are caused by bad designs, improper installations, insufficient bearing lubrication, improper alignment, and damaged seals. A R and A Plumbing and Heating that is properly installed and maintained has an expected service life of 30 years.
The most common defects found in hot water system circulation pumps include the following:

  • Bad couplings. Although pump couplings will wear out, they generally fail as a result of misalignment and vibrations. If the coupling is worn, properly align the pump and motor before returning the pump to service.
  •  Bad bearings. Pump motor bearings require periodic lubrication. Follow the manufacturer’s recommendations, as too much lubrication can be as damaging as too little.
