Sound of running water after shower faucet is turned off?

[jiggleLow]

This is a mysterious new development; after taking a shower, you can still hear water running somewhere in the pipes, but there are no leaks detected in the basement. (It would be easy to see any leaks as the plumbing runs through the exposed subfloor.)

However, the sound stops when the diverter valve is adjusted. Here's a short clip demonstrating:

Is there water dripping from the tub spout? Maybe its just a hiss caused by air entering the showerhead as the riser pipe drains.

As Jim said, this is normal for these two-handle deco valves.

The diverter is a very simple valve, and usually has a leather washer in it that soaks up when water is passed thru it.

Make a habit of emptying the showerhead by having the diverter partially turned, so that water drains from the shower down out the spout.
