underground gas Piping?

jim lockard

We use 3/4 inch or larger poly pipe that is purchased from Shenandoah Gas (the local untily) We bury it 18" to the top of the pipe, we place a foil marking tape and a insulated copper wire in the trench about 6" above the pipe. We have a conversion fitting that turns a 90 and converts the poly to steel. The pipe is leak tested with air pressure and the installation inspected before we can close the trench. We then pipe above ground from there. The key is I buy all the parts for the underground work from the gas company. As for the code NFPA 54 is the national fuel gas code and my installations do comply. Best Wishes J.Lockard

Underground Gas Line for Heater

Hi everyone, Hope you can help. I have an L.P. fired boiler for my swimming pool and I wanted to convert to Natural Gas. One plumber who gave me an estimate wants to place a 3/4 galvanized line in a 2" PVC Pipe under ground (About 20' long" and place a board on top of the pipes before backfilling. Sounds like a great Idea and I was ready to go with this company. Then, the 2nd estimate came in and this company said you are not allowed to place a galvanized pipe under ground in or out of pvs and that I had to use a poly something or the other type pipe. Neither compnay could provide me with "Code Requirements" for such a job and since my family's safety is a major concern, I was wondering if anyone could advise me or point to where I can obtina the code. I live in ling Island NY. East End.
Thanks!

Well, in PA

I am not sure of your locale, however here in PA for propane we can use either poly coated soft copper, or use specific poly piping, with special push to connect fittings. Must be buried minimum 18 inches underground. Must have a marking tape (foil tape with pipe content label that is laid a few inches higher than the pipe to prevent accident digging damage). Straight poly can be used for propane or natural gas. Copper is not allowed to be used with natural gas.

You can ask a local inspector to tell you what code is in your area. Be prepared to pay for a permit! That's okay, the permit is what helps protect you...

buried gas line in L.I.

I would contact Keyspan. They are or should be your gas supplier. They will have all the codes you need to know. I would also contact town hall (buildings dept.) for a list of licensed plumbers in your area. If they are on the list then they know your town and county codes. You can also try an engineer, but they may charge for the info.

pool heater

Hi: if you can swing it your best bet is to use a heat pump. Heat pumps are three hundred percent effient and will pay for themselfs in just a few years. I don't sell them but I have installed a few replacing oil, propane, and natural gas heaters.
