We have two Boilers heating house. One gauge shows 1 Psi the other 9 psi ?

Hi. We have two boilers heating this house. JStar installed them 12 years ago (Joe) from here. I notice one boiler shows on the gauge 1 Psi but the other is 9 psi.
Should this be like this ?
Thanks

Pics? @JStar , you still here?

One boiler probably has a bad gauge. The one reading 9 psi most likely.

Boiler gauges are on the system for a reason. If two gauges are on the same system they should read "the same" or within very close range of each other. Gauges DO fail i.e. get "stuck" or get plugged by debris.
They are easy to replace and not expensive. Their main purpose is to show that your system is not "over or under" pressurized and that your system is properly "filled."

or a pigtail is jelly

Oh thank you so much : ) So no chance of it exploding or something.
The Pigtails were cleaned at start of season to perfection (my wife got them from technician who was doing them in basement and took them to kitchen sink and cleaned them to perfection. : )
JStar no more here..we loved that guy through and through.

You say you have two boilers. Are they on completely separate systems? (For example if one boiler heats one part of the house, and the other another part.)

If so, there is no reason their measurements should agree. And if both pigtails are clear, you need to find out why one is reading so high.

New development. The one boiler gauge reading 1 psi I have kept running as it hasn't been cold..the one reading 9 psi I turned off. I expected if it is defective it would stay at 9 psi while off..but no, with boiler off it has dropped down to a little above 0.
Both boilers heat the same area..Steam one pipe cast iron radiators..Smith Series 8 Boilers.
Pigtails (Copper) were both cleaned before heating season in October...
Gauges flawed ? Or other reason ?

@Athana ...I might of tried swapping the gauges .. .. just make the boiler isn't  steaming when you do this . . ..

why not post a picture of the Ptrol and pigtail, the sightglass, and LWCO,

if you pull a wire from the Ptrol, can the boiler fire on a call for heat, it should not.

In your multitude of previous posts over the years since getting this dual Smith boiler arrangement installed you have repeatedly been asked for pictures so that the forum can properly help you out. You have also repeatedly been given local contacts in your area for expertise. Is there a reason you won't post pictures? If you do not know how then maybe we can help you with that.

Hi thanks Ive posted some pictures in the past but may have not known how in the earlier days. But for this one..the boiler was off and I wanted to be home when I turned this one back on to see gauge raise
and I haven't been home for doctor visits. I ran the boilers for a few hours and these are the gauges.
Picture #1 is at about 7 but was at 9 when I originally made this post..Ive had this boiler off since then.
The other boilers gauge sits as you see around 2..maybe that one is the flawed one ?
Im thinking to order two new gauges and have them replaced. When boiler was serviced Pigtails and these were taken off and well cleaned.I have attached other pictures of other gauges as well.
Low Water Cut offs are two Cyclegards.
Thank you

Are there zone valves in this system?

I was thinking of more of an all in one shot so we see a more general view,

well either the Ptrol is bad, or as well as the wife did cleaning the pigtail, something got missed at the boiler port, or under the trol,
hard to choose one from this side of the keyboard

like I said 14 posts ago your gauges are bad
