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.
Tricky Air leak

Here are some photos of the equipment pad in case that helps. The water you see there is from the hose. No water leaks that I have noticed.
Welcome to the forum
Just in front of the pump intake, is that a check valve or maybe a Flow-vis?

It’s a check valve.Welcome to the forum

Do you see any air (pump running) passing through that check valve? Even tiny bubbles?
I’ve looked in that one and in the one between my heater and the chlorinator and don’t see anything. I guess it doesn’t mean they aren’t there
I see bubbles coming out of my return jets. When my pump is on low to medium they only come out of one jet. When it’s on at 75% or higher they come out of several but they aren’t as concentrated so it’s harder to notice.
OK, if you have an air leak (pump running) those bubbles have to be from somewhere between your skimmer and the pump.....nowhere else. I don't understand why you can't see them as they pass through the system......UNLESS, you are seeing the small bubbles a salt water generator produces. Got a pic of the bubbles?
I don’t think it’s underground because I can isolate a line with the Jandy valve when on low and the bubbles come out of a different return.
I don’t have a pic of the bubbles but I could get one tomorrow. I would think I would see a considerable amount passing through the pump or in the check valves. When on low I do see a few bubbles in the pump but they are just moving around on top. I guess that’s why it’s difficult because it doesn’t make logical sense to me.
I could try turning of the salt generator and see if they stop. Didn’t know they produce bubbles.
Nope. Some are small and some are quarter size. When pump is on high they mostly all come out small.
