Ali: it is possible to increase the pressure of your shower head to what ever you would like to have. I once plumbed in a Cat piston pump from a car wash for a man that that had psoriasis. At a setting of 150 psi, he was able to care for his condition so well that he later went into the business of manufacturing a retro fit kit for those who suffer from the same affliction. Akmed LCMDG
Well…there is a few facts missing. Is this your only shower and you expected greater pressure? Are you on a well? Hmmm…. My guess… The shower head is new and has a limited flow for water conservaion…..swap out with a known “good flow / good pressure” head.
