Greeted Laurel at the door, whom directed me to the Bilko doors on the side of the house. Performed a visual inspection and began change out the oil filter, pump strainer and nozzle. Checked and inspected the gun assembly. Bled the oil line and checked for leaks. Fired up the boiler and observed it cycle until it reached temperature. All is well. Unfortunately the expansion tank is full of water and in need of replacement along with the water feeder w/backflow preventer and nipple. The two boiler heat supply risers are also full of rust. Several pricing options were created for consideration. I sat down and explained all of the options and issues with the boiler. Laurel would like to have the work done, but will apply for a Synchrony account to facilitate the ability to have the work done. Called FraBar for direction on how to proceed.
