I recently moved into a new home. One of the things I was getting around to doing was installing a hair catch for the bathtub, since there is no catch or drain stop installed. I purchased a universal hair catch at the hardware store and was about to install it, when I noticed there is standing water inside the drain. I then purchased a Drain Weasel tool to see if I could fish anything up, but to no avail; absolutely nothing comes up.
The water drains completely fine when the shower is running. If the spout is running, it is a little slower to drain. Here are a couple pictures for reference.
I find it interesting that the water doesn't get insanely backed up when I'm in the shower, yet this standing water never seems to drain. Is there possibly a clog somewhere deeper in the drain? Probably a job for the plumber? For the record, I live in a planned unit development.
