I have an in ground liner pool that is 3 years old. On Saturday I performed a backwash and rise sequence with my sand filter. On Sunday I noticed the water was low, added more water (didn't think anything of it at the time). Monday after work I noticed water loss again - so I added more water and marked the level. Tuesday afternoon I had 3/4" of water loss in 24 hours and Wednesday afternoon I had 1/2" of water loss in 24 hours (with the pool NOT running) yesterday afternoon I attempted to perform a die test to find a potential leak, no luck.

Has anyone else experienced a similar issue?

Well... it does not appear that the water is leaking back through the sand filter via backwash. I disassembled the piping coming out of the sand filter from the backwash, no water has been leaking out of there.

I performed a Dye test in the pool myself, it did not come up with anything leaking that I found.

Could it be that I am just experiencing that much of evaporation? The last few days the water loss has not been consistent, anywhere between 1/4 inch and 3/4 of an inch within a 24-hour. I do live in a very hot and humid climate in south Louisiana common this past week has been extremely humid.

I did...I did not have the bucket in the pool, I had the bucket adjacent to the pool right next to the lip in the shallow end. The results were inconclusive

We typically believe 1/4" daily is attributable to evaporation.......anything more than that should be considered a leak.

Do the bucket test precisely. It's a little trouble but the results are very conclusive.

To keep the effects of evaporation out of this test, fill a bucket with water, mark the level of the water in the bucket, set it on the stairs and compare the water loss between the pool level and the bucket level.

Thanks for the tip, I'll give it a shot. Unfortunately we have 80% chance of rain in my area for the next few days
