It is recommended that annual maintenance be done on mechanical equipment such as the pumps, hot water heater, controls etc. If there was a problem or failure, it is commonly found in these mechanical parts. It is recommended that the installer be contacted for annual maintenance.
For repairs to the system, the homeowner should contact the installer. Be sure to have your design plan available for tubing location.
To avoid unnecessary repair work, all equipment must be used and maintained in the manner in which it was designed and installed. Homeowners disconnecting controls or moving pumps can find themselves requiring repairs and possibly voiding their warranty.
Lifespan
While the heat source in a properly maintained system can last for as long as 30 to 40 years, PEX pipes set in the floor are expected to last more than 50 years. (Some test results indicate life expectancies of 200-300 years.)
