| Boiler flow problem
I have an old system in the house (1938) single pipe system with diverter tee's the old cast iron type main line is 1" reduces to 1/2" on the risers to the rads. when I purchased the house in 91 I replaced the boiler w/a raypack copper boiler I also replaced the rads with copper baseboard. everything worked fine. last year the boiler started leaking, I replaced with the same unit, I also replaced the spirovent. now I cant seem to get hot water into the baseboards I,ve bled and bled, and only been able to get 1 to flow, thought the problem might be the pump so I replaced the little taco it came with with a B&G 100, but still no go. the main line heats fine, but I cant get hot water to flow up into the baseboards any ideas out there? |
