Hey /diy/, so I had my boiler shut off for a little bit because the return pipe for the boiler blew a hole in a rotted out portion of it, and had that portion replaced as well had the low water cutoff circuit board replaced (which was faulty and may have increased the pressure in the return pipe causing it to burst).A boiler guy replaced the circuit board and turned the boiler back on, and told me to periodically open up a drain spigot behind the boiler (which I have hooked up a garden hose leading to the basement drain) and drain excess water from the boiler if I see the site tube completely full (pictured).So far there's been a slow current of dirty water flowing from it, and the site tube will dip occasionally below the safety line until a supply water pipe turns on and raises the site tube level past the safety line.Should I just leave the spigot on? Could that lead to a dangerous dry boil situation? Sorry if all my terminology isn't correct, I'm trying to learn a little bit and I don't want to sit in front of the boiler all night turning on and off the spigot

>>2891178This would be something to ask the guy who did the job, we don't know how shit's piped and what safety systems are running and how. >>2891180If you have any large buffers then it can take longer, if not, you should see some heating within an hour or so. Gas boilers are usually massively oversized.
