Ok.. so after a rather rainy may.. I finally got my pool up and running(diy install) Let me give you a quick rundown of my install and situation...
The pool is a dished out for 16' of the 18'.. anyways when i did the digging for the dish the ground was very soft.(we had a very wet spring..and have always had bad drainage in the back yard) after rolling and tamping it it seemed to be solid and felt stable so we set up and filled the pool.. that was about a week and half ago..
Now we come to the situation.. So Thursday of this week we had a large storm come through.. like 1" in 20 minutes..I noticed that the pool looks like it lost about an inch of water when I was at work..So I top it off and yell at the Kids for jumping off the ladder figuring I will have to find a hole and patch it in the ladder area the next day.
When I woke yesterday I did notice the pool dropped about 1/4' overnight.. so I knew i had a problem..When I got home yesterday I got in the pool and spent the next hour and a half looking for a leak that just does not seem to be there.. when in the pool I walked the entire surface and found no soft spots at all.. the did a visual inspection of every seam in the liner.. If i have a bad spot I sure the **** cant find it..
My concern is that even though I can not find a leak I still have the entire peramiter of the pool that is noticably damper then the dirt around the rest of the pool.. I did the bucket test last night and the pool and the bucket are within 1/8" of eachother.. I assume I don't have a leak but may be wrong.. after all I do have a solar cover on 99% of the pool (it folds back by the ladder) so I cant imagine that would allow for that much evaporation? speaking of this .. our night have been real cool and dry over the past week.. and of course humid last night possibly skewing results anyways.
So after my ramble I just want to see if this is possible: a far stretch but hear me out
My back yard has drainage issues ( hence it took it a week to dry enough before I could dig and was still a little mushy when I did dig).. Is it possible that my liner has settled 1 inch in the dish area due to the ground being a little soft at install? and if so could the water around the pool be groundwater being forced out from underneath.. Mind you i have an extremely high water table..like when I was digging the pool and hit 8" it began to rise and puddle in the bottom of the dish causing me to wait another two days to dig.. Everything is still level on the outside of the pool so I know the pool itself has not settled( we used blocks under all supports)..
