I have a bathroom shower that doesn't get used very often. I know at one time the water worked in the shower, now it doesn't. The faucet and toilet in the same bathroom work. I have taken off the shower head to see if it was clogged and no water comes through the pipe sticking out of the wall. Nothing... help.

What kind of faucet do you have in the shower. Are you sure that there are no cutoffs in the wall by the faucet, some states require a cut off at the site of the faucet. Tell me if you have two handles or one and give me some other info and I might be able to help.
