Master plumber, i am looking for help with a heating problem with seem to have begin when i decided to move my boiler 20 feet closer to my hot water heater in my basement. The plumbing work was done by my father, the electrical work was done with co-workers and the circuit breaker was mis-labeled and the electrican tripped the breaker while wiring the boiler at its new location. The transformer was thought to be burnt and the second electrican jumped out all the safety control and direct wired the gas valve at this point i only let the boiler run one night and had to manually feed water into the boiler. i must of over feed water to the boiler because water was pouring out of the air valves at the 1st and second floor. the third electrican who is used to control wiring, re-wired the boiler with the old transformer and everything worked, except that i don’t get heat out the the rear radiators i decided to take all the air vents off the rear radiators and now get heat off and on at the top floor ( 3rd floor ) rear radiator but nothing at the 1st, and second flooor. i was told to check the radiator for correct pitch and to disconnect and drain the radiators. after completing this still no change. i was also told to increase the pressuretrol from 1-2 lbs to 4-5lbs and still no change. i was next told to replace the air valve at the bottom of the riser ( below the ceiling of the basement ) still no change. the riser gets hot but the radiators are cold and there is very little steam coming out of the valves when the radiators are disconnected and the valves opened. my father wants to add in another air vent to the bottom of the riser, and call keyspan to complain about gas pressure but last winter the heat system work fine. My father is a plumber with 45 years experience, specialize in boiler installaton and heating, has his own company his partner has the license but this problem seems to be stumping him. I would appreciate any sugguestion or recommendation to another plumber / heating specialist
