John Nicolella did a great and very quick and neat job installing the new toilet and all seems to be working very well. He spent quiet a bit of time and did everything he could think of to identify and correct the vibration and noise on the vent the heater is running. He was able to confirm that the noise was not coming from the heater, itself but is coming from a part of the vent system. John did amazing work to identify the problem and we are very pleased with his perseverance and we are very much appreciate his efforts.
