Help, no water pressure

When I turn on the bath water the pressure is fine. I adjust the water temperature then turn the handle to activate the shower but the water barely comes out?? We don't have water pressure problem anywhere else in the house.

I'm thinking there might be a leak in the pipe the water travles through to get to the shower head.

thoughts?
 
If you still have water coming out the tub spigot then you probably aren't getting the valve/diverter opened fully. You COULD have a leak in the pipe, but I would suspect the valve first. I'd think you'd notice water on the floor or in the room behind the shower.
 
Just last month, my wife and I lost all pressure in our kitchen sink.

The problem?? Some sand clogged the filter near the head of the faucet. It wasn't at the tip of sink head (the filter there was clean)

It was the screen at the BASE of the sink head that some sediment.

I'd try that first. Just a tiny bit of sand in the screen messed up everything.
 
I've had shower heads get clogged up both from sediment and from lime, but the lime was a very slow process that didn't fit your description. The one that would just suddenly clog up was in an ancient house and huge black chunks of pipe would lodge in the one shower head. I didn't think that was a likely candidate for you. It's hard to say without knowing what your plumbing set up is, but many shower systems do not have any types of screens in them to clean. Two knob systems do not as far as I am aware. I have never dissected the single knob systems. Maybe if you describe the set up a solution might be easier to describe. It't pretty easy to remove a shower head and, without even taking it apart to see if it's gunked up, turn on the shower to see if that is where the pressure is lost. If you still have no pressure, you can plug up the tub spigot (on those systems where you activate the shower from the tub spigot). If you then get pressure it would be because the diverter is not diverting.
 
The first and easiest test is to take off the shower head and see if the flow is good with it off. If so, clean or replace shower head.
 
Thanks for the replies. This website kicks ***...

My set up is three knobs, two that control hot and cold and a third that controls where the water comes out - main faucet (tub) or the shower head. When I turn the water on and activate the shower head, no more water is coming out of the main faucet, but pressure is significantly decreased.

It actually was a "slow" process, I started noticing decreased water pressure about 2 weeks ago, which leads me to believe y'alls prediction is correct - probably just clogged.

i'm renting the house, it was built in the 30's.

Thanks
 
The house I was referring to was built in the 30's and the galvanized pipes were just slowly sloughing off metal flakes. They ended up in the last plumbing fixture in the line. I don't know why. If you take the shower head off to clean it out, go ahead and run it wothout a head for a bit. There would be black flakes equivalent to your standard bowl of cornflakes in the tub when I did that. Both size and quantity.
