The existing piping located between the two houses where the leak was present was cut out and removed. The damaged section was replaced with new PEX piping of the same size and type, with couplings installed on both ends to ensure secure connections. The new piping was properly hung and supported to maintain correct alignment and prevent future stress. The system was purged of air and tested to verify proper heating operation. All connections were fastened and tested, confirming a leak-free installation and reliable performance.
