You would think one could work out where the gas was leaking from. The actual source of ignition is less important.

Re: Carlin pro x 70200 message
Agree with @BDR529 your ohms should be like 700. Tech doesn't know that get a new tech or call the service manager. You're going to get lockouts with the ohms that high and the burner need cleaning and adjustment and a combustion test.
Re: What say you ? She’s steaming
Its time to replace that boiler. To buy yourself some time, use this.
Jb weld? Could work. This stuff will work. Read and follow the directions. This stuff was invented for this reason.

Check valve can't stop forward flow at all only reverse flow. Forward flow from the pump is same as forward flow coming from the return and thru the mix valve and the thru the pump.

Re: Marbles and Ghosts
nice article! I’m always looking for better visuals to help explain plumbing and Hydronics to my clients.
I was on a job recently with one of those giant tanks in the ceiling of the basement and puzzles over it because, yes indeed the pressure relief was popping. The client didn’t have a budget for getting rid of that dinosaur of a tank so I added a 5 gallon expansion tank that solved the issue.
