It never fails that when the cold weather sets in you find an issue with your heating system or even the battery in you car...today we'll talk about a high pressure reading in your home furnace (steam boiler is probably the correct terminology)....
Is the pressure gauge on your furnace (steam boiler) reading higher than normal (above 5 to 10 psi which is normal for most home furnaces)? Keep in mind that most steam boilers have a max rating of 15 psi and constantly running higher than that can result in boiler damage and costly replacement....
First check all air relief valves on each radiator to make sure none are clogged up due to hard water. Next you will be checking the pressure cutoff switch and the pigtail it's connected to which I explain in the video.
BTW the fix in this video worked for me and now the furnace (steam boiler) is operating at the correct pressure range....please note that if this fix doesn't work for you and the pressure cutoff switch is good you may have to replace the pigtail (the circular pipe hooked to the cutoff switch) as it may be blocked solid to the point that you can't get through it with the solder wire...
AS I SAID...IF I CAN DO IT...SO CAN YOU....Rob
Work done and video recorded by me (Robert Allen Mosley)

I'm commenting on my own video for this reason: Here we are two years since I did this simple fix and the boiler is still working correctly and pressure is right where it needs to be.
I’m not a pro and have basic knowledge. That said, I am curious if it would have been better to remove the pigtail and flush it out so sediment/gunk goes in the garbage instead of boiler. Maybe it doesn’t make a difference, IDK. Just a thought.
Boiler, boiler, boiler. Furnace uses air to heat. Boiler uses water or steam to heat. Not only does the boiler need to be flushed but the whole wet return needs to be flushed. You can also add a cleaning solution to help keep the return from building up sludge. You should have it professionally cleaned once in a while. Heat exchanger should be cleaned every so often. But it is good advice for home owners , keep it up.
I hear you...I guess my terminology isn't completely correct as I am not a professional. However I have been a mechanic/ maintenance person for most of my life and can use my knowledge to figure things out. I do appreciate the feedback my friend ...thank you.
Take the pig tail off and put a new one dont waste your time.
I was able to poke through it but I did tell people to replace it if they couldn't poke through the gunk...also keep in mind that I did this as a spare of the moment fix as no hardware stores were open at the time....
A furnace and a boiler are completely different items. Boilers have water and furnaces don’t.
Understood ...I'll admit my terminology was a bit off in my description of this . Thanks for the feedback. Also I admit I'm not an HVAC person but I do use my past skills to figure things out...
