Are you annoyed by the loud overflow noise? The annoying gurgling sound of you drain? Then adding a Durso standpipe is your solution. If your overflow can not fit a Durso then a Hoffman Gurgle Buster is your next best alternative.
Everything that you need to make the Durso can be found at your local Home Depot or Lowes.
If you have a 1 inch drain you want to make sure all of the PVC plumbing that you buy is 1.5 inch and at the bottom their will be a reducer to reduce it to fit into the 1 inch drain.
What's needed:
PVC pipe
Reducer that reduces pvc to your drain size
90 degree pvc elbow
pvc cap (This is where you will drill the hole for the air line tubing to be inserted)
Instead of an adjustable air valve as shown in the 3rd picture, I prefer using about 6 inches of air line tubing. You can adjust the level of water in the overflow box by pushing the air line tubing further inwards or pulling it outwards.
