I just completed a pool build. I have a Hayward vsp, de filter, heat pump and salt system. I installed a water temp sensor in the line and the next day had an air leak. One would assume it was due to the temp sensor which I placed between the pump and filter, however common sense says that would cause a water leak, not bubble from the jets. I dont have a ton of air in my filter pot and when I look in my jandy valves I don’t see bubbles. Ive tried reseating the temp sensor and putting lube around it. Ive checked all of my valves and made sure they are tight. I even took out my pump drain plugs and put teflon tape around them and reseated them. Still going on. Ive tried to figure it out with the water test, and haven’t been able to narrow it down. It’s got me stumped. Any suggestions.
