I've searched all the forums I can find to see if I can identify my problem and fix it but haven't had any luck so I thought I'd try posting to see if someone out there can help 
I live in a 2 story town house and the shower is upstairs. Whenever the hot water is turned on to a slow flow I get a constant shuddering sound behind the tap and the water spits out in a regular machine gun like flow. If I turn up the flow it runs smoothly. The cold water is not effected at all.
We have quite high water pressure and from what I've read that could be the problem. Here are a few things that I have tried/discovered.
When I start the shower vibrating then turn on the hot water at the sink next to it the vibrating stops. While I'm turning on the sink tap I can actually feel the vibrations coming though it :/
I've turned off the water flowing into the hot water system then run the shower until the water runs out but this hasn't helped.
I've also turned down the flow of water into the hot water system but I can't see a way to control the flow coming out.
I took the handle and flange of the tap to see if I could see anything but the spindle goes through the wall and is sealed with silicon so I couldn't see in behind it.
The house and plumbing is about 15-20 years old.
Can any one help me with this problem?
Thanks
