Changing a tub spout diverter is a relatively simple plumbing repair that can be completed in a few minutes. A tub spout diverter is a small, cylindrical device that fits inside the tub spout and directs water flow from the spout to the showerhead. Over time, diverter can become clogged with mineral deposits or debris, which can restrict water flow or cause the diverter to malfunction.
There are a few different types of tub spout diverters, but the most common type is a push-pull diverter. This type of diverter is operated by pushing or pulling on a small knob or lever on the spout. When the knob or lever is pushed in, water flows from the spout. When the knob or lever is pulled out, water flows from the showerhead.
