Re: Question about gas valve placement on the main inside a house, allowed or not?
i never understood the main gas shutoff requiring a tool to shut off, but there is a gas cock on the line just inside the foundation and another after the regulator.

Re: Question about gas valve placement on the main inside a house, allowed or not?
With the recent Task 87 gas rules, it's a game changer for even touching gas cocks before and around a gas meter. No more just shutting the first gas cock & changing an appliance or gas branch or riser cock. Mad Dog

In the recent past, a simple Master Plumber license allowed you to work on everything after the HP regulator. Mad Dog

this is typically what you see upstream of a meter, with a lock tab. It is a full port NG rated valve
Oddly enough the G in WOG was non flammable gas

Re: Boiler feed pumps options
The quick and cheap fix would be to install a square head plug cock in each pumps discharge line to throttle the pumps flow to what is necessary for each boiler. If these were large boilers there are a few better but more expensive ways to control the pumps flow. This will get you "out of the woods" as we say in my area.
Re: Packing Heat
The next step would be to look at your gas bills and find the month with the highest therm usage. Then look up insolation for your location for that month, and average high temperature for your location for your month. Figure out what kind of thermal collector you would like to use, and calculate its efficiency at that outdoor temperature, and figure out how many panels you'll need to produce the heat equivalent of that number of therms, at that insolation and efficiency.
That gives a lower limit on the size of a thermal system, you'd still need some sort of storage. But you can compare that to the PV size estimated above to get a ballpark of how competitive it will be.
Re: Burner technicians -what’s going on in this industry?
went to my gas code update this morning
2024 average age of journeyman plumber 49.9
master plumber 55.1
journeyman gas fitter 56.5
master gas fitter 60.00
employment for plumbers pipefitters etc is projected to grow 2% from 2022 to 2032
the project 5% to retire each year then the increase to keep pace would be 7%

Hi, I'd feel better putting a full port ball valve rated WOG downstream of the meter, if simply as a safety measure.

Re: Question about gas valve placement on the main inside a house, allowed or not?
Why would you need a valve on the main after the meter? If I want to work on the gas line, I shut the valve before the meter. It seems unnecessary.
