I live in 3rd floor condominium in New Jersey, last week we found a gas leak somewhere in my pipeline.
Plumber from home owner association disconnected gas pipeline from the meter and installed meter to pressure test the line with air. He also disconnected all appliances and put an end-cap on pipelines. Then he gave me big estimate to find the leak and fix it. Association gave me option to choose my own plumber to find the leak and have it fixed.
My question is, As a home owner (I don't have any license), can I find that leak in now dead pipeline myself? If leak is in one of the joints inside my walls, it would be easy for me and cheaper to point the leak to plumber to save some money.
I can hook up compressor to the line, build up required pressure and check if the leak is within my walls by spraying soap water on joints and look out for bubbles.
Gas line is dead, disconnected from the utility company meter.
