Replace the failed exhaust coupling with the OEM replacement part.
On time, professional and efficient.
I replaced the hyvent and relief valve. I capped an old supply loop that was never capped. I found the no heat upstairs to be caused by the thermostat being disconnected. The boiler exhaust coupling completely failed. I have shut the boiler off and it must remain off until we return to replace the coupling. I have made an estimate to replace it. Thank you.
Quick kitchen sink repair. Timely & friendly service. Thank you!
I replaced two ProPress supply valves today. After shutting off the water supply, I removed the old valves and inspected the copper piping for any damage or corrosion. Using a ProPress tool, I securely installed the new ProPress valves, ensuring a tight, leak-free seal. Once the valves were in place, I turned the water back on and checked for any leaks. The new valves are functioning properly, and the water supply is restored without any issues. The ProPress system provides a reliable and durable connection for the long-term performance of the plumbing system.
Performed routine maintenance in Rochester on a Rheem tanked water heater. Drained the tank to remove sediment buildup, inspected the anode rod for corrosion, and replaced it with a new magnesium rod. Checked the thermostat settings to ensure proper water temperature. Verified that the pressure relief valve was functioning correctly. After flushing the tank and refilling, the system was tested for leaks and efficiency, confirming optimal operation.
