Can't find leak

[dsinth]

I am at a loss to find the leak. I am losing about 1" per day until the water level reaches 1" above the skimmer mouth. I have let the water level drop 3 times and every time it stops at the 1" above the skimmer mouth line. This would suggest to me that he leak is in the liner, stairs or skimmer. I have dye tested around steps and skimmer and corners but still cannot find a leak. Your suggestions would be most welcomed. The liner is only 5 years old. Thank you!

Yes sounds like a liner issue. Check around the waterline, or inside the mouth of the skimmer. If the pool has a light it could be the conduit. If you are unable to locate the leak yourself you may want to have a leak detection company locate and repair the leak before you close the pool.
