It was brought to my attention that there may be issues with the liner stretch and not fitting to the pool until it does. I know that the liner should be allowed to "relax" on a warm day in the pool when filling, but if in fact the only available water source is well water (54 deg F) then won't the effect be the same in that the liner will become rigid, not relaxing to fit until the water warms up? Are we going to experience wall bending/buckle? How much? Being new to this, I wouldn't want to be freaking out thinking we got the wrong sized liner or that we did something wrong in constructing the sides or coving, etc. which caused this. Or is this completely rumor that this will happen??

Is there any benefit to trying to run that fill water through the solar panel sets somehow to warm it up some while filling? We have a J-Hook liner on an 18x33 buttress free.
