“I've read an alternative to replacing the pipe is to have the gas company replace their meter/regulator to increase my current gas pressure of 7"wc to 2psi. Then place a regulator at each appliance (Maxitrol 325) to reduce the pressure back to 7"wc. “ Other than the galvanized pipe, I don’t...

For small stuff, the Met-Fit line of mechanical fittings are great and easily installed. Like them much better for anything less than 2”

Hard to stray from Central - as long as you have someone for calibration and support.

Be sure to sleeve the riser in the concrete - just some pvc will do, and fill in void with some sand. The trench separation issue could be dictated by local code, just need to confirm that, if indeed there is any local authority where you are at. Otherwise, most utilities would like 1’...

If you do choose to have delivery pressure from utility increased to 2psi , you will need a regulator for each appliance. Otherwise, as Reach4 mentioned, by only placing one regulator just downstream of the meter you’re back in same situation with 6” WC. On already inadequate pipe size. The...

Glad your bathroom inspections went well - but I would urge you to have a certified gas fitter perform the work you described. Most municipalities or inspection authorities will require a Master Gas Fitter certification to pull the permit before inspection takes place.

Did the pressure stabilize or is it still dropping slowly? It should stabilize unless there is a big difference in temps. May want to check the schrader valve for possible leakage and another thought would be the key valves - make sure they are open and then cap or plug the terminations...

You are reading correct - but the inlet pressure to the regulator is most likely a good bit more than 5psi. Wouldn't want to speculate for sizing but guessing they are delivering at least 15#-17# to the inlet side of your regulator - that's considering it's an old system with cast iron...

If you are indeed on 2psi system through the meter, that meter is definately not undersized. My thoughts are the small pipe size entering the house in conjunction with the csst causing the noise. We have seen the csst tubing whistle before, although not as pronounced as in your video. Like H...
