A gas water heater needs the right gas pressure to fire properly, and low pressure makes the flame weak or the burner slow to light. The pressure is set by the gas supply, and it is a pro's job to check it.
The supply
The gas line to the heater is sized for the BTU load, and a line that is too small drops the pressure when the burner runs. mineral-rich water varies by region, and older neighborhoods still run on aging galvanized or copper lines In Danville, an added heater can starve the line.
The symptom
A burner that lights slowly, flames weakly, or goes out under load points to low gas pressure.
The measurement
A pro measures the manifold pressure at the gas valve with the heater running, and the reading tells the story.
The fix
The fix can be a larger line, a pressure adjustment, or a supply issue with the meter, and it is gas work, not a DIY job.
