WARNING THIS IS A POWER OFF AND WATER OFF REPAIR
your TAP WASHER on the shower needs (REPLACING ) this WILL END YOUR DRIP DRIP problem, the washer is located inside the shower on the bottom of the bit you OPEN to let the water flow, this is similar to a sink/bath problem IF THEY DRIP YOU CHANGE THE TAP WASHER (they do come in various sizes) I keep a combination of more than one size handy for repairs when shops ain't OPEN
