NG Gas
In most cities and communities the maximum pressure available depends on the codes for that area. Some will allow as much as 2 psi while others will have a limit that is under 1/2 psi.
Many torches like to see 5 psi, while others can operate with lower pressures (Cricket/Scorpion). Other torches require higher fuel pressures for best performance.
Overall, your installer is limited to local plumbing codes and what is allowed by the firm that supplies the natural gas.
Expect pressures in the range of 1/3 psi to perhaps 2 psi at the most. Pressures over this can be achieved by using a natural gas compressor.
