Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. First I’ll need some more info so I have a more complete picture of your situation.

What is the pressure on the gauge?

Customer: replied 11 months ago.
Hi Rick, Pressure is 0
Expert:  Rick replied 11 months ago.

Ok then that's why you have a PRO. I need pics of the piping around the boiler to tell you how to bump the pressure back up to 15 psi.

Customer: replied 11 months ago.
Ok, I'll take pics
Expert:  Rick replied 11 months ago.

Need pics of all the piping not the gauge

Customer: replied 11 months ago.
I just sent several pics.
Expert:  Rick replied 11 months ago.

I only see one and it doesn't show me what I need. I'm looking for the feed valve (see attached pic for typical) on the water line into the boiler. It's usually 1/2 pipe.

Customer: replied 11 months ago.
Is this the one you need?
Expert:  Rick replied 11 months ago.

Not at all like my pic. All feed valves no matter the manufacturer have the same basic shape with a sort of bell shaped top. They are also in a water line not directly conected to the boiler like this pressure relief valve. There is one other possibility if you can't find it show me a picture of the expansion tank (see attached, could be different color)

Customer: replied 11 months ago.
Did you get the pics of the expansion tank and relief valve?
Expert:  Rick replied 11 months ago.

Sorry no
