Tip 7: Don't blow a gasket — replace it. If you have water dripping from the shower spout, most of the time the cause is a defective washer or defective seat within the its body. As long as you have isolation valves to isolate water to that area, it should be a relatively easy fix. Isolate the water to that shower, disassemble the handles and take out the stem where the washer is; then replace, reinstall and observe it.
