Beware of St marys plumbing they installed a heater in my home with the wrong flue pipe and now the heater is venting Combustion gases into my home causing potential carbon monoxide poisoning. St marys plumbing was paid through national fuel to do this job and now refuses to correct the problem they created. I contacted Ed McNeal the owner to make the repairs and he refused to pay for fixing his mistake and then attacked me personally. I have contacted the bbb and attorney general and will be filing a small claims case against them to get the heater fixed properly. One phone call to them could jeopardize you family's life so call someone that knows what they are doing. Beware!!! Also check this company's bbb profile as you can see the complaints are piling up due to their shoddy work.
