I have some 1" OD plastic natural gas pipe I need to replace. I would like to splice it in to the existing pipe under the house as I really don't want to have to dig all that up. Since I really don't want to go to the Home Depot I'd like to order it on line and have it delivered but I'm not sure exactly what I should buy. Any and all help would be appreciated. I have a few pics of the existing pipe so you can get an idea of what I'm dealing with.
