    Anyone who have a problem with too much noise in their overflow- here is a solution for you guys!!

    [FONT=Arial,Helvetica]Above are the approximately $3 worth of PVC Parts Required (air tubing not shown) [/FONT]
    [FONT=Arial,Helvetica]Notes: The coupler is 1.5" (female slip) x 1.5" (female slip), and the[/FONT] [FONT=Arial,Helvetica]bushing
    is 1" (female slip) x 1.5" (male slip). Also, some overflows may require [/FONT]
    [FONT=Arial,Helvetica]another 1" x 1" coupler to attach to the overflow's standing pipe.[/FONT]
    [FONT=Arial,Helvetica]STEP 1 : Sand 1" inside of the 1.5" (male) x1" (female) slip bushing such that it can[/FONT]
    [FONT=Arial,Helvetica]slide over the 1"-in-diameter pipe with considerable resistance. [/FONT]
    [FONT=Arial,Helvetica]A dremel is recommended (but not required) for this step.[/FONT]
    [​IMG]

    [FONT=Arial,Helvetica]STEP 2: Press the coupler and bushing together to form bell (aka flow bell).[/FONT]

    [FONT=Arial,Helvetica]STEP 3: Drill 1/4" hole in top-center of 1" end cap and push the air tubing through. [/FONT]
    [FONT=Arial,Helvetica]The air tubing should slide with considerable resistance through the hole.[/FONT]
    [FONT=Arial,Helvetica]Drill 5, 1/2" holes or any assortment of large holes in 1" pipe. [/FONT]
    [FONT=Arial,Helvetica]Holes need to be roughly positioned as shown below.[/FONT]
    [​IMG]

    [FONT=Arial,Helvetica]STEP 4: In picture above, take end cap and push it on 1" pipe on the side that is about 2" [/FONT]
    [FONT=Arial,Helvetica]from top of holes). The end of the air tubing should rest a little bit below the drilled holes.[/FONT]
    [​IMG]

    [FONT=Arial,Helvetica]STEP 5: Push together all parts seen in step 3 (and in that orientation) together.[/FONT]
