I have a 1" black gas main. It has several spare T's along it capped for
growth @ 1/2"
Can I run one 1/2" line upstairs, put a T in it with one line about 10" long
with a valve for a gas stove and the other line through a wall for a 10K BTU
heater with it's own valve as well? How about larger or smaller heater size?
Can I run one 1/2" line up and across the unfinished utility room ceiling
from it and back down again to a T with two shut offs for two side by side
Thanks as usual.
We need to know more information, such as BTU rating on the gas stove and
dryers and the total length of run of the gas pipe. Also meter size, and how
long of run the 1" pipe is at the various take offs.
The 1" run may be too long to do much, plus adding more runs may require
added meter capacity.
You may need to have the meter changed to 2 PSI, and add regulators to each
Don't know as I don't own any of them yet... won't be fancy or expensive,
From the main to the stove T will be about 10' then 10" to the stove and a
foot or two through the wall to the heater.
Don't have a meter... but I'm going from 20# down to a 1/2# regulator where
I enter the house
22' overall on the main. 11' to the stove/heater takeoff, the dryer takeoffs
are at the 17' mark, at the end of the 22' main a 1/2 line goes another 3'
to a new 70K furnace and past that another 2' or so is a flex line to a 30K
space heater (runs at min setting unless the electric is off for the
The line to the dryers would go a total length up/over/down of 20' where
they would supply side by side dryers of the garden variety.
I ran 1" main 40 feet to an 100k btu forced air heater with 3' of 1/2" as
From there it was 3/4" another 25 feet to a the stove, with 8 feet of 1/2"
drop. Then 3/4 to the dryer.
With out a schematic of your COMPLETE gas system there is little exact
information that can be given.
Time for some calls to the local pros
My gas company will not increase pressure to residences. no matter what.
Ever notice that at Burger Dude, the gas line is usually 1" coming in and
3-4" after the meter and regulator?
Burger Dude may have a 2 PSI supply pressure too!
I piped one job that had a three million BTU load, 2 PSI gas pressure. We
had to really get out the calculators and tape measures to pipe it all with
If this is the Service pipe from the Gas Main in the road then NO, yo
cannot touch it. No CORGI engineer has permission to touch as ga
service pipe without consultation from the relevant Gas Transporte
If, and I stress IF, as your description sounds, this is the Servic
pipe, a Govenor will be required, I assume that the current 1" suppl
you speak of is connected to a meter and regulator.
These other services require metering also. If you require a large
load capacity from your service you will need to contact your ga
If you tie into one of these other capped service pipes, you will b
committing Theft of Gas.
Please correct me if I'm wrong about the assumptions I make from you
