Hello all,
I am in Northern California. Bought a house with a pool spring of 2021. I noticed a 1/2 inch a day pool leak during the summer and got a Leak Detection company locate the leak in my light fixture. It took the Leak Detection 3 visits to find the leak, which cost me about $1k. My pool has an attached spa. No waterfalls or any other features.
I have had my pool covered with a solar cover (not sealed) for about a 9 days and I am seeing a 14/32 inch water loss. temps are around 50-60 during the day and 40 in the evenings. I have tried doing a bucket test and Im losing a bit more on the pool side. I have called the company that performed the leak test, but they told me its not enough of a leak for them to be able to find the source. They also told me that it may not be a leak. I have called a few other leak detection companies and they told me the same thing. I do have a tiny drip of water coming from the pool filter where the gasket is. I tried fixing this a few times and have tightened it. But even this is not very much. It is just a drip or so.
If it is a leak, it is miniscule, that detecting where could be difficult. It is too cold for me to dive into the pool to even try.
Question is, do you folks think this is a leak? If so, I do have a company that is willing to check, but they are scheduled over month out. Any suggestions for me?
Thanks in advance.

So I have a question(s). How exactly did they attempt to find the leaks previously? Was it with dye coloring, did they physically go in the water? Did they use listening scopes, deck plates, or other sensitive listening devices? Did they pressurize the system for these tests?
We know that water loss is common in the winter simply due to the drier air. Wind maybe not so much for you with the cover on. Since pressure testing ruled-out the plumbing, it would see(common) and patching at the rear of the niche can sometimes be frustrating. In warmer water, I would check the drain again though. I suspect you have a hydrostatic valve and sometimes their seal gets compromised with a bit of grit or debris. Tough to do a DIY dye test down there unless you have portable air to go slow and take your time.
