Haha, I can now understand why my plumber had a hard time figuring this out. You're right, I did say that. When my plumber turned the gas back on after he extended the run for the fireplace, he remarked that he was surprised how quickly that the gas reached the stovetop as he bled the...

Less than 2 psi. The most conservative inlet pressure chart in NFPA54 assumes a less than 2 psi pressure. That’s the chart I used to come up with a max length of 100ft

Thank you all. It looks like Massachusetts allowable pressure loss is up to 0.5 WC (CMR 248 Amendment 5). Someone commented that I overestimated my grille BTU, and they were right, even 40K BTU would be conservative. Referencing NFPA 54, conservatively (assuming <2 PSI inlet pressure, I bet...

Currently (without the extension for the grill) there are four 90 degree fittings (no 45s at all) including the first vertical to horizontal 90 off the 1" supply. There are also two 3/4 x 1/2 x 3/4 tees for the 1/2" reduced run to the fixtures (1/2" runs are less than 3 feet). If we extended...

My plumber has extended a 3/4" black iron gas line that originally supplied just my stove cooktop to a future for a fireplace. The total run is 45 ft of 3/4", reduced to 1/2" after a two separate tees that then feed up about 3 ft to the two fixtures. The stove is only gas for a cooktop (oven...

Solved. It ended up being a supply stop that failed. When I went to dig in deeper, shut off the water at the stop but water kept trickling thru. Then when I went to open the stop, flow was even less. I replaced the sweat stops with compression stops. Cleared out all gunk and calcium from the...

Hi- I'm a new DIY-er with average plumbing experience. I am having hot water flow/pressure issues at one fixture (kitchen sink). Some notes below: 1) All plumbing is either copper or pex. Home was built in 1997, so relatively new plumbing. All the plumbing is in the basement ceiling and...
