Oh yeah, it really needs to go all the way to the ground. Water hitting the ground from 3 feet up will be noisy. The only other thing I can thing of is a heavy chain running from the bottom of the drain pipe but that seems like more work than just attaching a three foot extension with a couple of screws.
When are women going to face the fact that they donít know their own bodies as well as men who have heard things?
