Reasons why the condensate- or boiler-feed pump is

Jun 25, 2014· The boiler pressure is too high. The condensate pump's job is to put the returning condensate back into the boiler. To do this, the pump has to produce a pressure that's higher than the boiler's operating pressure. As a rule of thumb, if the boiler operates at 50 psi or less, the pump should discharge at the boiler's operating pressure, plus
