Thanks so much. I will call a tech no problem. I called a technician previously and he showed me how to bleed the pipes (He didn't want to stay because he said it will take a long time and didn't want to stay so he showed me instead). I guess he was just a bad technician. Just curious, do you have ideas on what caused the boiler to steam. I'm thinking there is just too much air in the pipes perhaps?
I won't call any tech anything without knowing the details, but I can tell you that I would NEVER leave a boiler in a customer's hands simply so I wouldn't have to hang around. as far as the steam it could be that the system was very low on water and there was steam in the lines, it could be that while bleeding it, it drained faster than it should have without getting fill water back in fast enough due to the proper valves not being opened/closed, and an "air pocket" formed in the water jacket, which caused water to flash to steam. it could be any of a list of things, just one of those situations where you want a tech there in person with an eye on it s they can assess the danger level of what is happening
Yeah, I noticed that the system was low on water while I was bleeding it I think. Anyway, I will call another technician to check it out. Thanks for the explanations. This helped me greatly.
You're more than welcome. Good luck with your boiler, hopefully it will be as simple as a quick fill and bleed.
