In fairness to all, we don't discuss pricing on the Wall. Thanks for your cooperation.
I've got a Smith G-8 steamer- only about two years old. Last year I was fretting that I was losing water- I had to top up the boiler about once a month because it would shut off on low water. Eventually decided that this wasn't enough to worry about- evaporation and a few iffy vents could account for the water loss.
Well, this year the problem is cropping up more frequently. Last night I got home to find the boiler shut off due to low water. I tried filling the boiler to the header to check for a leak- nothing (at least nothing conspicuous). I topped up the boiler to the normal water level- around 8:00 last night. As of about a half hour ago the boiler is off again due to low water. I've got two "suspicious" radiator vents, but no other obvious signs of water loss. All new returns (above ground) etc.
Any advice? Steam pros around here are slim pickings ("Have I ever heard of Hollo-who?").
