I had an issue where my water heater kept shutting off/pilot

I had an issue where my water heater kept shutting off/pilot went out. It's an AO Smith with a sealed combustion chamber. A technician came out and changed the thermocouple but it required the full assembly, due to the design. A week later, the problem recurred. I called another plumber out and he removed the seal and ignitor and we have to light it manually now but he says it should stay lit from now on. Is there any safety concern?JA: OK.

Pearl, I'm fairly sure I've got a bad thermocouple on an

Hi Pearl, I'm fairly sure I've got a bad thermocouple on an AO Smith water heater. The pilot lights just fine, but goes out as soon as I release the button. I bought a universal replacement thermocouple, but now that I've pulled the burner assembly out, I see that the original has a little resistor or diode built into it. The universal replacement does not have this. Do you know what the purpose of that diode is? Is it safe to install the new thermocouple that does not have one?JA: Sometimes plumbing issues that that you think will be really complicated end up being easy to fix.

I had an old set of gas logs in my fireplace. They burned

I had an old set of gas logs in my fireplace. They burned fine. But they were ugly. We purchased a new set and switched them out. Now the pilot light won't stay lit. And if the pilot light stays on, when you turn the burners on and turn it back off the pilot light goes out. I have found that if I only open the gas valve to the fireplace a little bit, the logs work fine. Everybody kept telling me the gas pressure was too low that's why it was shutting off. But it appears that the pressure is too high by the fact that when you open the valve just a little they work. Is this correct thinking? Is it ok just open the valve a little? Is there any danger involved in that? Is there another solution? Thanks. Rod.
