Do you have a slow draining tub? Do you stand in two inches of water while showering? Not only is this irritating you also end up having to clean the tub more frequently. Before you call a plumber try this.
Remove the overflow with a flat head screwdriver and pull the rod out (first picture). Most likely there will be a hair clog connected to the rod. (Second picture) clean the rod and replace it. If this doesn’t solve your slow draining tub for your Tahoe house call us and we will run a snake down the overflow.
