Welcome! Here are some tips for using this forum.
We have 2 concurrent problems. In 2008 we had our old steam boiler replaced with a Burnham model PIN75NI-ME2. We've had a cold winter in NJ and we have heard the water filling often which we were told we should rarely hear. On 2 occasions since January, we have found sandy water on the floor in the basement. We are having a room added on the back of the house and when I showed the contractor the water on the floor (thinking the foundation was disturbed) he suggested I call the boiler people. Sure enough when they arrived (the same people that installed the boiler), they found the cast iron block inside the boiler was corroded and now has holes in it. We are shocked this could have happened so quickly when our old boiler was ancient! The concern now is why and how to avoid it moving forward??
Secondly, one of our guest rooms on the second floor has always been a bit chilly. We are careful to replace the valve air vents as needed (Varivalve) but the original pipe was downsized in a renovation prior to our ownership. It went from 2" (throughout the house) to 1-1/4". During this recent work, that same pipe had to be relocated so I mentioned it to the heating contractor. They assured me the 1-1/4" should be ok. We closed the door to the room last night to "test" and although the radiator was hot this morning, the room was at least 10 degrees colder that the others and the hallway outside the room. I'd appreciate any feedback, suggestions, comments you have.
