I have a 2021 4 person saluspa. It seems air is leaking from the liner behind the plate the filter screws into from tube c. When removing the screw holding The top of the assembly there is a little plastic valve set into the liner. The valve has three holes around the center of it that is leaking air from the liner and allowing water into the liner. Has anyone else ran into this issue or know of a fix? I'm uploading a picture of the part that is leaking the air
