LWCO and feeder maintenance
I have a 10 year old steam boiler, with 24v McDonnell & Miller LWCO and automatic feeder. The only routine maintenance I had been doing is weekly draining the sludge, the installer did not tell me about the recommended annual cleaning of the water feeder filter. This winter the boiler overflowed, I presume due to a speck of dirt or similar in the water feeder valve and the water trickled into the boiler and eventually the mains and through the air vents. I will be replacing the feeder. I am now aware of additional manufacturer recommended maintenance: Inspect the LWCO probe annually and replace every five years, replace the complete LWCO unit at fifteen years, and replace the complete water feeder unit at ten years. My questions are: 1) when someone in the trade comes across these, does anyone actually routinely replace these parts at these intervals, or do they only get replaced when they fail? 2) Does anyone really routinely inspect the probe? 3) I tried removing the probe with a monkey wrench and a pipe as an extension, but couldn’t. Any reason I shouldn’t use an impact wrench to remove it?
