Water Feeder Overfilling and Shut Down
I have an oil fired boiler for hot water and steam heat. The auto filler frequently overfills the boiler causing it to shut down. It calls for water even when the water is almost to the top of the sight glass. It does this both during the heating and non-heating season, so doesn't appear to be from water returning slowly. I'm pretty good at draining the sediment on a regular basis trying to keep what I assume is a float valve unobstructed. I've had my oil company service people look at it several times (I think Dan would refer to these people as knuckleheads). They messed with settings on the filler, but nothing changed. Is there any harm in simply shutting off the water supply valve to the auto feeder and monitoring and manually filling as needed? Or should I find someone who knows what they're doing and get the feeder fixed or replaced?
