Upon inspection, the existing water heater was due for replacement and the boiler’s automatic water feeder was found to be malfunctioning. We removed the old water heater and professionally installed the homeowner-supplied unit, added a new thermal expansion tank to protect the plumbing system from excess pressure, and replaced the defective boiler water feeder to ensure proper and automatic system water replenishment. All water connections were completed in accordance with current plumbing and mechanical code standards, the system was filled and tested for proper operation, and all components were verified for safe, leak-free performance. The system is now operating reliably, providing safe hot water and improved protection for the home’s plumbing and heating systems.
