I just had my liner replaced and now when the filter pump is turned on, the aqua genie is shooting the water up instead of down which is causing the water in front of the skimmer to "boil" which is affecting the circulation of the water. My pool guy came back to evaluate the problem but could not come up with a definite cause. His first theory is that the "front Plate" warped while sitting in the hot sun while the replacement process took place (3 days). His other theory is that the replacement gasket for the front plate is too thick. The front plate will not go flush. The pool is 20+ years old and there have not been any problems when the liner was previously replaced. Does anyone have any suggestions that I can give to my pool guy? Thanks
