 Faucet doesn't immediately turn on or off
Author: broox (IA)

I have a Delta wall mounted bathroom faucet (Model: 3559LF) that is behaving in a way that's not nearly as elegant as the unit looks.

When you turn on the faucet, it either starts with a blast of air and then fast flowing water or slow flowing water followed by the blast of fast flowing water. When you turn off the faucet, it's almost as if the spout drains out before turning off.

Installation of the valve was pretty straight forward with the single shower-like rough-in valve.

The spout itself contains an o-ring and slides over a piece of copper pipe that comes from the main valve and protrudes from the wall. The valve is (unfortunately) sitting behind a finished, tiled wall.

Any ideas what may be causing this?

For reference, here's the product and installation doc:

Thanks!

The spout IS draining out after you turn the faucet off, which is why water continues to come out. The aerator creates a restriction to rapid draining, so it probably drips for a considerable time afterwards. When you turn the faucet on, the spout has to fill with water, which creates a rush of air first.

Hmm, is this something that's unique to wall mount faucets? None of my other faucets do this...
