Customer called in about a leak coming from either the humidifier or water heater. Upon arrival, customer let me know, water leak has dried up, but it was present the day before. Upon further inspection discovered that the leak was coming from the T&P valve of the water heater. Checked water pressure to the house and water pressure was sitting at 90 psi. Expansion tank bladder bursted and it’s now full of water and not doing its job. Informed customer due to the high water pressure from the city and the expansion tank bladder bursting inside is causing the T&P valve from the water heater to leak due to high pressure build up when water heater is heating. Gave customer different options and customer decided to go with the first option which is replaced PRV, expansion tank and T&P valve. Started by drain down the house down repiping the main entrance area and install a new ball valve and PRV. Set pressure to 75 psi. Went ahead and also replace the expansion tank and T&P valve to the wate
