A customer in Morristown, NJ called Pipe Works Services about their water heater failing inspection. Pipe Works Services technician Mario was dispatched to see exactly what was going on. Mario diagnosed the venting was not changed from a 3-inch smoke pipe to a 4-inch smoke pipe. Most town coding requires this to be changed when replacing a water heater. Mario was able to replace it so the water heater venting was up to code and able to vent properly when in use.
