Any Gas Appliance Experts in Here?

    Had the plumber come back but this time the owner showed up. He listened to me lay out the entire sequence of events then started troubleshooting.


    When he opened the line to the stove it screeched like a banshee. It’s not supposed to do that. The plumber that moved it over SHOULD have put a regulator on it. All he did was cut the pipe and shift it 28”. The reason the stove didn’t work is because the built in safety valve cut the gas off. It does that when the incoming pressure exceeds 2 PSI. Had it not done that we would have had a 2 foot flame from the burners.


    So I’m out another $700 but it’s fixed now.


    He was nervous about cutting into my ceiling downstairs so I did it. I measured 3 times and cut once. I looked up into the hole and there was the pipe into the kitchen. He couldn't believe it. To be honest neither could I.

    Live and learn I guess.

    HMM. I've always understood that the regulator where it enters the house drops it to 10 psi or so? (LP, mind you) So, NG only wants TWO?

    I think that he needs to call the gas company and have them come out and check the regulator at the meter set before we see him in the news. Typically when they scream like he mentions, there is more than 10 psi on the line.

    I’ve learned a lot in the past few months, especially the last two weeks.


    The meter has either a red or white plate. Red face place means high pressure system. White face plate means low pressure system. High is better.


    Every appliance on a high pressure system needs a regulator to drop the pressure down from 2PSI. The gas line to my tankless heater is labeled 2PSI and has a regulator at the input to the heater. Same for our HVAC system. When we opened up the joist cavity and saw there was no regulator we knew what was wrong.


    I will be calling the plumber that moved the line about this. If he gets an attitude with me the county inspector will be contacted. If you have a business and claim to be a gas fitter you damn well better know what the fuck you are doing.


    The first plumber never cracked the line open so he never knew is was at line pressure. His boss is going to have a chat with him and discounted my bill to compensate me for my time and trouble.


    Stove will be delivered and connected tomorrow.


    I’d be very interested in an online class that covers this topic in more detail. Add me to it.

    Yeah well,


    Not one time over the last 40 years have I encountered a "high pressure" system in a residence.


    While by no means encyclopedic, my experience with natural gas is pretty comprehensive. Gotta be a reason for the non-conforming supply. Unless code's way different from the few states I've worked in. Wonder what else is custom.


    Happy Hunting!

    1/2” is more than enough as it turns out. With all 3 appliances operating I’m at 600,000 BTUs and I could easily add more.


    He said high pressure is 2PSI, low is about 1/2PSI and those systems are more problematic.


    This is gas, not air, so ‘high’ doesn’t mean what we think it means in this case.


    Been an informative week to say the least.
