    Default Internal filter piping hole

    I have a Hayward C3030 filter housing and on the pvc 90 fitting at the bottom there is about an 1/8 hole in the side of the fitting. If you are looking at the inside of the housing with the top off with the inlet and outlet directly in front of you it would be the 90 on the bottom and the hole is on the left side. At first I thought the pipe cracked or something, when I pulled the pipe out i saw this hole. It looks like maybe it is supposed to be there. Anyone know if it is?
    The fitting looks like it has a molding mark right where the hole is. So I though maybe the fitting may have blown a hole in that location from a molding defect.

    I already looked in the manual and it doesnít say anything about a hole. Also the pictures of unit do not show one.

    Any one know or have one laying around, that could look and see if has a hole.

    Any help would be appreciated.

    Filters often incorporate various venting schemes to vent air accumulation, and avoid dissolving gases, air-locking or a gas pressurized casing . . .

    [Gas pressurized filter cases have -- when opened without venting -- killed or injured pool owners and pool guys.]
