Propane questions

We are in the process of building a house. The house is on a site where a double wide sat which we sold. In the process we had to move the propane tank. I want to run a line from the tank to the house then continue on to the garage. I also want to run a line from the tank to the shop. I have had some experience with plastic lines and think they would be a significant savings over Copper.

I have been told I need a high pressure red regulator at the tank and lower pressure regulators at the three buildings. I was also told that the risers for the plastic lines require a special tool. Several years ago I helped lay some plastic propane lines and the risers just snapped on the plastic lines much like Sharkbite on PEX. Special fittings were also mentioned.

Any comments?
 
Yes, I would be talking to my propane company for information & advice, instead of a tractor forum/tool bunch of guys. :roll:
 
I have plastic from my propane tank to the house, the propane company put it in for me. They tested it also.
 
I might be a total moron......but....I would go with a tried and true metallic line, remember this will be a permanent thing.
I am not belittleing plastic but there is a place for plastic, and it isnt to be buried to hold Propane or nat. gas. Just my opinion here.
I have never heard of such a thing.
 
21 years ago, when we ran propane underground two different directions from the tank, the company used yellow plastic line with one-time-only-push-together steel risers. I had to provide the excavation. I found out the hard way that it should be run in conduit. I don't know if it was sliced with a knife, or a rock, but one of the lines leaked immediately.
I expect your local propane supplier will tell you what method they use/approve of today.
You are correct on the regulators. Tank reg. drops PSI to 5-10. Building regulators drop it to about .5 PSI.
 
You might ask the propane supplier what they want to see installed. After the initial fill during my home construction they would not bring any more until everything was inspected by them.
 
I suggest you dig your trenches, then just call your propane supplier and have them hook you up. The cost will be minimal and the job will be done right. Anymore, plastic is the standard for gas lines, but not all plastic pipe is approved for gas.

Gas companies have been using plastic gas lines for years....they work well and are easy to repair if needed. I definitely wouldn't use black pipe as the handle seems to suggest. Too many joints to leak and corrode with no way to access them...
 
Again,

There is a certain plastic pipe, and fittings used for Propane. PLEASE have someone put it in and inspect it that is certified. You can dig the trench if you want. Make sure and tape a wire to it so that it can be located.
 
My propane company ran the lines for free. All plastic, but they apparently know what they are doing, never had a problem.
 

Inlaws had a new line run by the propane company a few years ago. The line appeared to be plastic but was plastic covered copper.

If I ran plastic I would put it in a sleeve to protect it and also you could sniff the sleeve and tell if it was leaking and would make replacement easy.

You may also be required to put locator tape over the line for future locating. Required in many areas.
 
The type regulators depend on pipe size and distance. A single regulator at the tank can handle everything if it i pipes are large enough.
I would rather regulate the pressure at the tank even if it requires 2 regulators. In the unlikly event the line is punctured,the lower line pressure would be benifacial.
