Plumbing in the Home/my shower

Question
water just stopped coming out of my show head . it was working fine in the morning and that night it wasn't working at all. It is a 3 knob set up and when I turned the shower knob it stops the water coming out of the faucet but nothing comes out of the shower head. I removed the shower head and cleaned and also tried it with the shower head off with just the arm sticking out and still no water.

Answer
To repair the problem you will need to turn the house water supply off and bleed off the pressure at any faucet both hot and cold. You will need to remove the center stem and possibly you will be able to see what is causing the problem; there are several things that could have happened but most likely the washer and screw have backed off the end to the diverter stem and is plugging the outlet to the riser to the shower head. Possibly you can see the obstruction and using a pick or needle-nose pliers or even make a tool with wire to remove the restriction. BUT you may ultimately have to back pressure (or use a flexible wire) from the shower head arm (head removed) and possibly you may have to use air pressure to clear whatever foreign material has entered the shower riser.
If it has been several years since maintenance on the valve you certainly should consider replacing all the parts in all three stems---also inspecting the seats and replacing them if they are not really smooth.
If you have no clue to what I am suggesting or if you do not know how to remove the stems (usually requires shower valve socket AND neutral spacing of the stems) then I think it is time to call a plumber.

PLEASE read this entire introduction. I have been doing this for a long time and I have come to the conclusion that if you are not willing to take the time to write a detailed question then don't expect a detailed solution! I am getting far to many questions that do not give enough detail to warrant a good solution. I realize it is a little difficult to formulate a good question but if you want a good answer you have to give me good details....read this entire introduction please....remember this website is world wide I have no clue where you live if you don't tell me.....to give more detail on the fixture you are having problems with...a one piece eljer 3.5 gallon flush will be totally different than a one-gallon flush toto.....details are important. I can answer most questions related to residential and commercial plumbing for many buildings. I have sufficient knowledge of the UPC and UMC. I will speculate for you if necessary. In those cases I will try to give you some guidance and you should use that to refine the question further and we, together, can seek the answer via a follow up. Plumbing codes and practices vary around the world--If you don't tell me where you live the answer I give may not fit your locality. I am giving my time to you as a way of fulfilling my perceived obligation to share. I am here to try to help you find a solution to your problem. REMEMBER, If you want a good answer you need to ask a detailed question and include where you live, type of pipes, type of building, water pressure if it is a water problem, type of heater, age of appliance & building all these and many more are variables that have an effect on various situations. Detailed information will help produce a better answer.
