noise in line

William Sankey

we have a weil-mcclain 68 oil fired boiler and ever since the serviceman cleaned our furnace about two months ago we have had an excessive amount of noise during the circulation cycle. now I know that there will be some noise during circulation, like a rolling brook, but now it sounds like a RAPIDS. Is this to be a matter of concern? aU3LgzgB
