Last Saturday we had a new 24' Round Above Ground Pool Professionally installed. Sunday morning I noticed at just one section the sand/dirt was wet right against the pool wall. I immediately sent an email to the pool installer who said that this is normal because of the cold water and the warm ground;the liner was sweating. During the last 3 days we had lots of Rain here in NJ so it has been impossible to see if that area is still wet. It has also been hard to check the water level because of all the heavy rain; but I didn't notice a water level drop; just a gain because of the rain.
Is this normal for a new pool/liner to sweat? I am just a bit concerned and won't really know for a couple of days since the sun is finally out today.
