Hi,
I am planning on installing a portable shower and the overhead water
tank is just one foot above the shower head. I need to know how can I
increase the water pressure at the shower end without the use of any
pump.
Could this be acheived by increasing the shower line piping dia ?
Please see my diagram for referrance: http://rayhaun75.googlepages.com/SHOWER.jpg
Please advise...............shall be very grateful to you.

Regards
Rehan
