<br/>Merry Christmas everyone<br/><br/>Just discovered a PVC fitting in the cabinet under my fridge. It's against the outside wall. Looks like a Tee or Wye fitting with a 1 1/2 inch plug. Just curious as to what it might be used for. I thought maybe it was for central vacuum or ice maker??? A quick look in the outside compartments under the fridge and I can't find anything. <br/><br/>Thanks<br/>Ed
