If you are a pool technician you may be interested to know what the sound of water in a gas line sounds like.
I don’t see this very often but I came across this job yesterday and it was so significant I wanted to share it to help others.
As I state in the video, the gas heater will struggle to fire with water in the gas line and if it does it decreases the gas pressure to the heater which will lead to sooting of the heater and will decrease the life of the pool heater. The solution is to locate the leak and repair it. Many times the damage is so significant a new gas line must be run 🙁
