Hey,
Last year we had natural gas run to our home. The plumber used galvanized pipe from the meter with the 2 PSI regulator to the outside wall of the house. Inside he used ¾†CSST to a ball valve on 3/4†black iron pipe where there is a dirt trap pocket/drip leg. Next is the Maxitrol 325-5AL600 pressure regulator with an OPD, then ¾†black pipe to the manifold where ½†CSST goes to the boiler.
I just bought a natural gas grill that I need to run a gas line to and I need some advice. We will add a few more gas appliances to the system in the future. I am going to use ¾†black iron pipe and run a main across the basement past the location where future taps will come off of it. The gas grill will be at the end of the main and it will be reduced to 1/2†pipe. I plan on using galvanized pipe for the brick wall penetration and a brass isolation valve outside at the grill. From there I plan on more galvanized pipe to the grill. Everything will be above ground.
Here are my questions;
1.I have read the galvanizing flakes off of the inside of the pipes when exposed to natural gas. Do I need to put a dirt trap pocket/drip leg in the line at the grill?
2.I have read there is electrolysis between brass and galvanized pipe so the pipe will corrode away eventually. Is this true and if so how do I avoid it?
3.Will I have electrolysis between black iron and galvanized pipe?
4.I live in Baltimore County, Maryland. Can I use the black iron pipe outside and paint it to protect it?
5. If I can use the black pipe outside should I still use a drip leg at the grill?
Thanks for your help, Tom
