Steam boiler losing water
I have a single pipe steam system.
Everything had been working fine, no water loss.
Then a horizontal pipe about 6" x 1-1/4" adjacent to the boiler developed a pin hole leak.
I couldn't get my regular guy to replace, he was too busy.
I taped it with electrical tape. That worked. Boiler was not loosing any water.
Since I was going away for 2 weeks, I didn't want to risk it.
So I had another guy who I didn't know replace it.
He just drained the boiler from the low water shutoff.
He replaced the small piece of pipe. It took him about 15 minutes, he charged me $ ( his explanation travel time).
He was only alone for 2 minutes, while I ran upstairs to raise the thermostsat.
The pipe does NOT leak, but the boiler water level now mysteriously goes down.
This was NOT happening before even with the pipe taped.
Now I need to add water every 3 days or so.
I have checked everywhere and do NOT see any leaking water.
It just seems like an incredible coincidence that this problem developed immediately after the repair.
