new liner. corners have about 1 to 4 inches gap between liner and walls

[waltb]

Had new liner installed couple weeks back. The pool liner all four corners from bottom of the wall to coping have a range of 1 to 4 inches air gap behind. Non are sitting flush and one deep corner pulling out of the coping. Pool installer did not use vacumn behind the liner when filling. said he could push wrinkles out but appears this has given problems at the corners. Pool is 36X18 inground with 8 ft deep end. is this normal and will streatch to corners in time..or is this a workmanship issue. (installation, manufactured wrong, measured wrong or ??)
Any professional advice will be appreciated

Might stretch 1". Won't stretch 4" (that's 16" all around).

If it has been cut in, you are probably stuck with where it is. If not, drain, and vac.

The liner was either measured wrong or cut wrong....either way its wrong! I would insist on a re-do.
