I needed to tap into an exisitng 1" natural gas line to feed

Customer Question

I needed to tap into an exisitng 1" natural gas line to feed a new dryer. After installing a 1" x 1" x 1/2" T in my black iron pipe line, within 10 feet of the meter, the new valve "rattles" when turned fully on. At half-way or three-quarter open it does not make a sound.
JA: Thanks. Can you give me any more details about your issue?
Customer: After the T then1" line reduced to 1/2" tobfeed my HWH.
JA: OK got it. Last thing — HVAC Technicians generally expect a deposit of about $18 to help with your type of question (you only pay if satisfied). Now I'm going to take you to a page to place a secure deposit with JustAnswer. Don't worry, this chat is saved. After that, we will finish helping you.

Hello and thanks for using this service, if you have been waiting do not worry or get upset. I am Appliance Guru an extremely experienced tech on here and I try to get to as many customers as I can. I just picked up your question now. ANSWER: Are you sure you do not have a high pressure gas line run to your house? Basically do you see a round regulator on all other devices that run on gas from the gas line going to each unit?
Customer: replied 8 months ago.
The outside meter has a round regulator. Furnace, oven/stove and HWH do not have any external regulator.
