Thanks for a great place to learn!
I am hiring a professional to install a NG pool heater. The installation instructions require an inch and one-half pipe for the 150 ft. run over a mostly flat grade. I am looking for information and advice on the pros/cons on the types of materials available/recommended/required by code for this job. Black Pipe, Stainless Steel Corrugated, Galvanized Pipe all come to mind.
Anything new on the market?
What should I steer clear of?
Any comments and opinions, as well as experience when using these material. I would like to have a basic knowledge of material choices when getting the bids.
1-1/2" gas line? Are you sure??? That's a heck of a lot of gas. That sounds like the diameter of the water lines running to the heater, but not a gas line. The gas line shouldn't be more than 1", more likely 3/4". You can't use galvanized for NG, and around here you can't use black pipe either. You have to use the plastic stuff that looks like pex. It used to be if you used black pipe, you had to coat it in this tar crap, then wrap it in tape, then tar it...it's real messy and a pain. The plastic stuff is nice and easy, but has to be run by a pro. I know around here you can call the gas company and tell them how long of a run you need and they will make it up with the fittings for you, then you can bury it and install it yourself.
