Hey guys, really appreciate this forum as someone doing most of their home build themselves. I have a question regarding gas line pressure test. I will have two gas appliances, a tankless heater and a gas stove. I have run the CSST line and installed the rough stub outs. Pressure testing at 15 psi easily stands for 30 minutes, and will remain unchanged for about a day. After 1-2 days you see about a 1/4lb drop in pressure. This is with temperature and reading time remaining consistent. It will very slowly continue to drop. After a coupla-few weeks down to 7-8 lbs of pressure. I have pumped it up to 15psi and repeatedly checked for any leaks with standard oatey leak detector and see zero signs of leaks. Have done this 2-3 times. Have even pumped it up to 20-30psi and still see no leaks with leak detector.
Should I worry myself over this? Thank you all.
