I'm getting conflicting information regarding my pool heater problem. It won't ignite. Warranty guys for the heater said a component blew out due to water in my gas line. They said this since when they turned on the heater, they heard a gurgling sound. The heater seemed to ignite, but they shut it off concerned about the gurgling sound. When they took off the cap below the vent on the regulator, water came out. My neighbor (just listening to my recount, not seeing the set up) first thought water may have been left in the line (said it would be rare) since the pool build construction (spring of 2015) when we had an exceptionally wet spring and first part of summer. A plumber came today and said he would be back Monday to blow out any water in the line, but he said water in the line would be rare. My neighbor came back this evening and looked at the set up. He said the vent for the regulator should not be facing up and thus catching water. He now thinks, the water was just in the regulator interfering with even flow of gas to the heater. I'm not sure what to think.
Here's a photo looking down on the regulator with the vent facing up (rusty looking). Can anyone tell me what may be going on? I trust ya'll! Thanks so much! Suz
