I have poor pressure to my shower hose. I have found that opening my hot water supply valve (its the one leaving the hot water tank to go to the taps) increases the pressure which is a great quick fix!! but is it safe to alter this supply valve??
I am a complete ignoramous when it comes to plumbing!!
there is no reason to leave this valve semi closed. open it fully then turn it back a quarter of aturn .this ensures the next visitor to this valve knows if its on or off
