I own a 40 year old home in AZ that has an Orangeburg pipe teed off the mainline to a faucet. The pipe is leaking under the driveway but I've managed to dig it up and exposed about 3 feet. I'm trying to figure out the best way to cap the line, I'll worry about supply to the faucet later.
If it only feeds a faucet, you may be able to slide 1/2 or 3/8 pex inside the existing pipe.
Agreed. If it's a single line, you can cut each side of the leak and put a pex connection on it. Otherwise, three feet is also enough room to cut out the leak and solder a new pipe in place.
This is the first time I ever heard of orangeburg pipe being used for pressurized water delivery. If he has some pics of how they applied fittings to it to use with a typical water system, faucets, etc, I'm sure others here would be interested in seeing it too.
As to passing a PEX through it, I think you have an excellent idea there. Wonder what size this pipe is? I've never seen O pipe smaller than 4", which was used for sewer and similar. For a faucet supply it really sounds bizarre.
How does one put a PEX connection on orangeburg pipe? Soldering it must be even more interesting.

There are vague references to it as supply, but I've never been able to confirm ever really was...although guess somebody could do anything once, particularly if weren't subject to Code/inspection at the time or a homeowner/DIYer did something on their own.
I've no idea what would use for pressure fittings, Fernco?
I do know that industrial use during wartime, was used for saltwater disposal in oil production that was pressure, but that was far cry from residential potable water.
Smallest I've seen mentioned was 2" and only applications I know of were waste/drain, agreed.
Wonder if it really, truly is...altho guess it'd be hard to misdiagnose if dug it up...pictures/more info would be nice.
replying to dpb, Joe Kauffman wrote: It's 3/4" pipe, says Orangeburg SP 160psi Water on it. My Dad owned an underground construction company here for 30 years and said almost all the services they ran back then for water was this pipe and used brass compression fittings, but since new homes have changed, we can't find any fittings. Which seems strange because there's thousands upon thousands of homes in the Phoenix area that have this pipe installed. The leak is under a 24' wide slab of driveway and I have no interest in repairing so I found the pipe before it runs under that concrete and just want to cap it off. Hopefully this picture helps.

Orangeburg "SP" is a polyethylene pipe. It is not the Orangeburg pipe of the 19th through mid 20th century which was made from wood pulp and pitch pressed together.
If the concrete is only 24" wide, you could probably use a pressure washer to free the pipe and replace it with a new pipe of different material.

Better put your bifocals on and look again... :)
Oh? What did I miss?
h. Water Service Pipe: Polyethylene.
Found ASTM 3350 which gives table of dimension systems for given pressure ratings find
Standard Dimension Ratio Standard Pressure SDR (In the Case SIDR (In the Case Rating (psig) of Pipes Made to of Pipes Made to HDS = 800psi Standard OD?s) Standard ID?s) 11.0 9.0 160
which tells what the diameter ratios were for 160 psi pipe (culled the table down simply for the one of interest) and, one presumes, the CTS=OD spec means they used the OD spec's. Hence, a current manufacturer's polyethylene fittings for OD-sized pipe _should_ work.
Hadn't know this part on history--Orangeburg Mfg was bought out by Flintkote some time back in '50s (found ad for the CP pipe archived from a Life magazine in '59 where were listed as a Flintkote company). Flintkote was primarily an asbestos roofing and siding, etc., manufacturer from 1900 on until after WW II began buying up other building product companies such as OB. But, they fell prey to the asbestos hysteria and filed permanent bankruptcy in 2012...all there is no is the case lawyers fighting over the trust funds left from the disposal of assets.
' vis a vis "
Indeed, commented more fully above; thought I'd just mention the "orangeburg" word brings out recollections of essentially nothing but the old bituminized drain/waste pipe.
Hence the initial responses, that Orangeburg made other product is bascially known, just tends to not be referred to as such; the term having become so widely associated with the other, original, product.
Excellent explanation......... ;-)
Correct. I completely ignored the part he said Orangeburg. Forget what I said.

Irrigation pipe is sometimes connected with dresser couplings. It's a compression type fitting that can connect two pipes with without any additional fittings.
or
There must be a reason these won't work.
Orangeburg in name only. It is a plastic pipe that can us compression or sharkbite fittings.
Oragneburg pipe is fiber pipe.
