Sounds crazy, I know!

The project involves one maximum 150LnFt of gas line, total 950cfh. From the meter to the house is nearly 30', which will be 2" buried iron pipe.

However, at point of entrance for the line, is an area of traffic for the HO, and I'd like to have a 1" ball valve that will extend out of the soil, then go through the footing and into the house, where it will be split to the areas where needed.

The question is, for the areas exposed, I'd like to have a 1" or 1-1/4" line and ball valve that won't exceed 16" in reduced line, then back to 2".

How much will this affect the BTU requirement and total flow of the required gas?

Thanks, as always!!!

Not my field, but I'll bite. Reducing the cross section by that much would make a significant difference in available flow rate, even for a short distance. How critical that is would depend on how closely the pipe size was calculated to begin with.

I wouldn't do it. Can't the valve be mounted somewhere else?
