As well, if you have Sulphur in your water supply it smells bad and can permeate the decor of your bathroom. Neither of these two effects is pleasurable and should be avoided.

Removing the knob from the diverter is not an easy task. I recommend the use of a gear puller to do so. This helps avoid damaging the surrounding tiles. Once it’s off, bend the metal tube behind the knob. Next cut away the caulk around the metal plate, giving you access to the diverters.

If you have a rotating valve, it will be necessary to unscrew the nut at the stem allowing you to remove the whole assembly. It is important to take this piece with you when purchasing a replacement part. Doing so allows the salesman to easily match it up to the original for a proper fit.
