Our shower just shuts off by itself after 1 minute. When using the shower, the water runs for about 60 seconds and then just stops. The water is still on and will run in the bath if we turn the knob, but when we turn it back to the shower it's still stopped. When left alone for a while and the water is turned on again, it runs through the shower ahead, but again, lasts only about 60 seconds and shuts off. We tried draining all the water thinking the air vent had filled with water. This helped a little for the first time and then the problem started up again. Any ideas?

Have you tried removing the shower head to see if the result is different? Sometimes water restrictors break and can caus that problem. Then after the pressure gets relived there is a path for the water to pass through.

Start there if you haven't and see what happens.

We tried that and without the shower head we had the same problem, there is a lot of calcium build up in this area, but we are not having problems with any other faucets. Thanks, any other suggestions?

Please tell us the brand and the model number of your faucet, it sounds like you have calcium build up inside the faucet and it needs to be cleared it you respond to my question and we will tell you how to clean it, Thanks.
