The pipe connecting to my water heater is leaking

The pipe connecting to my water heater is leaking. The most common cause of this is the use of corrugated copper flex lines to connect to the water heater. At Benjamin Franklin Plumbing our plumbers’ hard pipe all water heaters with heavy duty type L copper tubing and use dielectric nipples and unions to connect to the water heater. This virtually eliminates the chance of a leaking pipe at the water heater.
